In an extremely short period of time, the shallow river IJ turned into a wide estuary, which from then on offered the Amstel an open connection to the Zuiderzee, IJssel and waterways further afield. This made the water flow of the Amstel more active, so excess water could be drained better. With drier banks, the downstream Amstel mouth became attractive for permanent habitation. Moreover, the river had grown from an insignificant peat stream into a junction of international waterways. A settlement was built here immediately after the landscape change of 1170, and right from the start of its foundation it focused on traffic, production and trade; not on farming, as opposed to how communities had lived further upstream for the past 200 years and northward for thousands of years. The construction of a dam at the mouth of the Amstel, eponymously named Dam, is historically estimated to have occurred between 1264 and 1275. The settlement first appeared in a document concerning a road toll granted by the count of Holland Floris V to the residents apud Amestelledamme 'at the dam in the Amstel' or 'at the dam of Amstelland'. This allowed the inhabitants of the village to travel freely through the County of Holland, paying no tolls at bridges, locks and dams. By 1327, the name had developed into Aemsterdam. Middle Ages Amsterdam was granted city rights in either 1300 or 1306. From the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League. In 1345, an alleged Eucharistic miracle in Kalverstraat rendered the city an important place of pilgrimage until the adoption of the Protestant faith. The Miracle devotion went underground but was kept alive. In the 19th century, especially after the jubilee of 1845, the devotion was revitalised and became an important national point of reference for Dutch Catholics. The Stille Omgang—a silent walk or procession in civil attire—is the expression of the pilgrimage within the Protestant Netherlands since the late 19th century. In the heyday of the Silent Walk, up to 90,000 pilgrims came to Amsterdam. In the 21st century, this has reduced to about 5,000. Conflict with Spain In the 16th century, the Dutch rebelled against Philip II of Spain and his successors. The main reasons for the uprising were the imposition of new taxes, the tenth penny, and the religious persecution of Protestants by the newly introduced Inquisition. The revolt escalated into the Eighty Years' War, which ultimately led to Dutch independence. Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Huguenots from France, prosperous merchants and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city's intellectual tolerance made Amsterdam a centre for the European free press.

Centre of the Dutch Golden Age The 17th century is considered Amsterdam's Golden Age, during which it became the wealthiest city in the western world. Ships sailed from Amsterdam to the Baltic Sea, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network. Amsterdam's merchants had the largest share in both the Dutch East India Company and the Dutch West India Company. These companies acquired overseas possessions that later became Dutch colonies. Amsterdam was Europe's most important point for the shipment of goods and was the leading financial centre of the western world. In 1602, the Amsterdam office of the international trading Dutch East India Company became the world's first stock exchange by trading in its own shares. The Bank of Amsterdam started operations in 1609, acting as a full-service bank for Dutch merchant bankers and as a reserve bank. Decline and modernisation Amsterdam's prosperity declined during the 18th and early 19th centuries. The wars of the Dutch Republic with England and France took their toll on Amsterdam. During the Napoleonic Wars, Amsterdam's significance reached its lowest point, with Holland being absorbed into the French Empire. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. The end of the 19th century is sometimes called Amsterdam's second Golden Age. New museums, a railway station, and the Concertgebouw were built; in this same time, the Industrial Revolution reached the city. The Amsterdam–Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. 20th century–present Shortly before the First World War, the city started to expand again, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato rebellion). People started looting stores and warehouses in order to get supplies, mainly food. On 1 January 1921, after a flood in 1916, the depleted municipalities of Durgerdam, Holysloot, Zunderdorp and Schellingwoude, all lying north of Amsterdam, were, at their own request, annexed to the city. Between the wars, the city continued to expand, most notably to the west of the Jordaan district in the Frederik Hendrikbuurt and surrounding neighbourhoods. Nazi Germany invaded the Netherlands on 10 May 1940 and took control of the country. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to a high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported to Nazi concentration camps, of whom some 60,000 lived in Amsterdam.

More than 100,000 Dutch Jews were deported to Nazi concentration camps, of whom some 60,000 lived in Amsterdam.

In response, the Dutch Communist Party organized the February strike attended by 300,000 people to protest against the raids. Perhaps the most famous deportee was the young Jewish girl Anne Frank, who died in the Bergen-Belsen concentration camp. At the end of the Second World War, communication with the rest of the country broke down, and food and fuel became scarce. Many citizens traveled to the countryside to forage. Dogs, cats, raw sugar beets, and tulip bulbs—cooked to a pulp—were consumed to stay alive. Many trees in Amsterdam were cut down for fuel, and wood was taken from the houses, apartments and other buildings of deported Jews. Many new suburbs, such as Osdorp, Slotervaart, Slotermeer and Geuzenveld, were built in the years after the Second World War. These suburbs contained many public parks and wide-open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other events of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing, politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings, and also for new roads, as the automobile became available to most people. A metro started operating in 1977 between the new suburb of Bijlmermeer in the city's Zuidoost (southeast) exclave and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect Amsterdam Centraal and the city centre with other parts of the city. The required large-scale demolitions began in Amsterdam's former Jewish neighborhood. Smaller streets, such as the Jodenbreestraat and Weesperstraat, were widened and almost all houses and buildings were demolished. At the peak of the demolition, the Nieuwmarktrellen (Nieuwmarkt Riots) broke out; the rioters expressed their fury about the demolition caused by the restructuring of the city. As a result, the demolition was stopped and the highway into the city's centre was never fully built; only the metro was completed. Only a few streets remained widened. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organizations, such as Stadsherstel Amsterdam, were founded to restore the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing. The entire city centre has reattained its former splendour and, as a whole, is now a protected area. Many of its buildings have become monuments, and in July 2010 the Grachtengordel (the three concentric canals: Herengracht, Keizersgracht, and Prinsengracht) was added to the UNESCO World Heritage List. In the 21st century, the Amsterdam city centre has attracted large numbers of tourists: between 2012 and 2015, the annual number of visitors rose from 10 to 17 million. Real estate prices have surged, and local shops are making way for tourist-oriented ones, making the centre unaffordable for the city's inhabitants.

These developments have evoked comparisons with Venice, a city thought to be overwhelmed by the tourist influx. Construction of a new metro line connecting the part of the city north of the IJ to its southern part was started in 2003. The project was controversial because its cost had exceeded its budget by a factor three by 2008, because of fears of damage to buildings in the centre, and because construction had to be halted and restarted multiple times. The new metro line was completed in 2018. Since 2014, renewed focus has been given to urban regeneration and renewal, especially in areas directly bordering the city centre, such as Frederik Hendrikbuurt. This urban renewal and expansion of the traditional centre of the city—with the construction on artificial islands of the new eastern IJburg neighbourhood—is part of the Structural Vision Amsterdam 2040 initiative. Geography Amsterdam is located in the Western Netherlands, in the province of North Holland, the capital of which is not Amsterdam, but rather Haarlem. The river Amstel ends in the city centre and connects to a large number of canals that eventually terminate in the IJ. Amsterdam is about below sea level.

The city's three main canals are the Prinsengracht, Herengracht and Keizersgracht. In the Middle Ages, Amsterdam was surrounded by a moat, called the Singel, which now forms the innermost ring in the city, and gives the city centre a horseshoe shape. The city is also served by a seaport. It has been compared with Venice, due to its division into about 90 islands, which are linked by more than 1,200 bridges. Climate Amsterdam has an oceanic climate (Köppen Cfb) strongly influenced by its proximity to the North Sea to the west, with prevailing westerly winds. Amsterdam, as well as most of the North Holland province, lies in USDA Hardiness zone 8b. Frosts mainly occur during spells of easterly or northeasterly winds from the inner European continent.

While many towns in Holland experienced population decline during the 15th and 16th centuries, Amsterdam's population grew, mainly due to the rise of the profitable Baltic maritime trade after the Burgundian victory in the Dutch–Hanseatic War. Still, the population of Amsterdam was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanised area of the Low Countries. This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. Jewish people from Spain, Portugal and Eastern Europe similarly settled in Amsterdam, as did Germans and Scandinavians. In thirty years, Amsterdam's population more than doubled between 1585 and 1610. By 1600, its population was around 50,000. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilised around 240,000 for most of the 18th century. In 1750, Amsterdam was the fourth largest city in Western Europe, behind London (676,000), Paris (560,000) and Naples (324,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than England, France or the Ottoman Empire. In contrast to those other metropolises, Amsterdam was also surrounded by large towns such as Leiden (about 67,000), Rotterdam (45,000), Haarlem (38,000) and Utrecht (30,000). The city's population declined in the early 19th century, dipping under 200,000 in 1820. By the second half of the 19th century, industrialisation spurred renewed growth. Amsterdam's population hit an all-time high of 872,000 in 1959, before declining in the following decades due to government-sponsored suburbanisation to so-called groeikernen (growth centres) such as Purmerend and Almere. Between 1970 and 1980, Amsterdam experienced its sharp population decline, peaking at a net loss of 25,000 people in 1973. By 1985 the city had only 675,570 residents. This was soon followed by reurbanisation and gentrification, leading to renewed population growth in the 2010s. Also in the 2010s, much of Amsterdam's population growth was due to immigration to the city. Amsterdam's population failed to beat the expectations of 873,000 in 2019. Immigration In the 16th and 17th century, non-Dutch immigrants to Amsterdam were mostly Huguenots, Flemings, Sephardi Jews and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War. The Westphalians came to Amsterdam mostly for economic reasons – their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty percent of them survived the Shoah.

Days with more than of precipitation are common, on average 133 days per year. Amsterdam's average annual precipitation is . A large part of this precipitation falls as light rain or brief showers. Cloudy and damp days are common during the cooler months of October through March. Demographics Historical population In 1300, Amsterdam's population was around 1,000 people. While many towns in Holland experienced population decline during the 15th and 16th centuries, Amsterdam's population grew, mainly due to the rise of the profitable Baltic maritime trade after the Burgundian victory in the Dutch–Hanseatic War. Still, the population of Amsterdam was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanised area of the Low Countries. This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. Jewish people from Spain, Portugal and Eastern Europe similarly settled in Amsterdam, as did Germans and Scandinavians. In thirty years, Amsterdam's population more than doubled between 1585 and 1610. By 1600, its population was around 50,000. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilised around 240,000 for most of the 18th century. In 1750, Amsterdam was the fourth largest city in Western Europe, behind London (676,000), Paris (560,000) and Naples (324,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than England, France or the Ottoman Empire.

The first mass immigration in the 20th century was by people from Indonesia, who came to Amsterdam after the independence of the Dutch East Indies in the 1940s and 1950s. In the 1960s guest workers from Turkey, Morocco, Italy, and Spain emigrated to Amsterdam. After the independence of Suriname in 1975, a large wave of Surinamese settled in Amsterdam, mostly in the Bijlmer area. Other immigrants, including refugees asylum seekers and illegal immigrants, came from Europe, America, Asia and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third planological bill of the Dutch Government. This bill promoted suburbanisation and arranged for new developments in so-called "groeikernen", literally cores of growth. Young professionals and artists moved into neighborhoods De Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. Today, people of non-Western origin make up approximately one-fifth of the population of Amsterdam, and more than 30% of the city's children. Ethnic Dutch (as defined by the Dutch census) now make up a minority of the total population, although by far the largest one. Only one in three inhabitants under 15 is an autochthon, or a person who has two parents of Dutch origin. Segregation along ethnic lines is clearly visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighbourhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord. In 2000, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (8%), most of whose followers were Sunni. In 2015, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (7.1%), most of whose followers were Sunni. Religion In 1578, the largely Catholic city of Amsterdam joined the revolt against Spanish rule, late in comparison to other major northern Dutch cities. Catholic priests were driven out of the city. Following the Dutch takeover, all churches were converted to Protestant worship. Calvinism was declared the main religion; although Catholicism was not forbidden and priests allowed to serve, the Catholic hierarchy was prohibited. This led to the establishment of schuilkerken, covert religious buildings that were hidden in pre-existing buildings. Catholics, some Jewish and dissenting Protestants worshiped in such buildings. A large influx of foreigners of many religions came to 17th-century Amsterdam, in particular Sefardic Jews from Spain and Portugal, Huguenots from France, Lutherans, Mennonites, as well as Protestants from across the Netherlands. This led to the establishment of many non-Dutch-speaking churches. In 1603, the Jewish received permission to practice their religion in the city. In 1639, the first synagogue was consecrated. The Jews came to call the town 'Jerusalem of the West'. As they became established in the city, other Christian denominations used converted Catholic chapels to conduct their own services.

The oldest English-language church congregation in the world outside the United Kingdom is found at the Begijnhof. Regular services there are still offered in English under the auspices of the Church of Scotland. Being Calvinists, the Huguenots soon integrated into the Dutch Reformed Church, though often retaining their own congregations. Some, commonly referred by the moniker 'Walloon', are recognizable today as they offer occasional services in French. In the second half of the 17th century, Amsterdam experienced an influx of Ashkenazim, Jews from Central and Eastern Europe. Jews often fled the pogroms in those areas. The first Ashkenazis who arrived in Amsterdam were refugees from the Khmelnytsky Uprising occurring in Ukraine and the Thirty Years' War, which devastated much of Central Europe. They not only founded their own synagogues, but had a strong influence on the 'Amsterdam dialect' adding a large Yiddish local vocabulary. Despite an absence of an official Jewish ghetto, most Jews preferred to live in the eastern part, which used to be the center of medieval Amsterdam. The main street of this Jewish neighbourhood was Jodenbreestraat. The neighbourhood comprised the Waterlooplein and the Nieuwmarkt. Buildings in this neighbourhood fell into disrepair after the Second World War a large section of the neighbourhood was demolished during the construction of the metro system. This led to riots, and as a result the original plans for large-scale reconstruction were abandoned by the government. The neighbourhood was rebuilt with smaller-scale residence buildings on the basis of its original layout. Catholic churches in Amsterdam have been constructed since the restoration of the episcopal hierarchy in 1853. One of the principal architects behind the city's Catholic churches, Cuypers, was also responsible for the Amsterdam Centraal station and the Rijksmuseum. In 1924, the Catholic Church hosted the International Eucharistic Congress in Amsterdam; numerous Catholic prelates visited the city, where festivities were held in churches and stadiums. Catholic processions on the public streets, however, were still forbidden under law at the time. Only in the 20th century was Amsterdam's relation to Catholicism normalised, but despite its far larger population size, the episcopal see of the city was placed in the provincial town of Haarlem. Historically, Amsterdam has been predominantly Christian, in 1900 Christians formed the largest religious group in the city (70% of the population), Dutch Reformed Church formed 45% of the city population, while the Catholic Church formed 25% of the city population. In recent times, religious demographics in Amsterdam have been changed by immigration from former colonies. Hinduism has been introduced from the Hindu diaspora from Suriname and several distinct branches of Islam have been brought from various parts of the world. Islam is now the largest non-Christian religion in Amsterdam. The large community of Ghanaian immigrants have established African churches, often in parking garages in the Bijlmer area. Diversity and immigration Amsterdam experienced an influx of religions and cultures after the Second World War.

With 180 different nationalities, Amsterdam is home to one of the widest varieties of nationalities of any city in the world. The proportion of the population of immigrant origin in the city proper is about 50% and 88% of the population are Dutch citizens. Amsterdam has been one of the municipalities in the Netherlands which provided immigrants with extensive and free Dutch-language courses, which have benefited many immigrants. Cityscape and architecture Amsterdam fans out south from the Amsterdam Centraal station and Damrak, the main street off the station. The oldest area of the town is known as De Wallen (English: "The Quays"). It lies to the east of Damrak and contains the city's famous red-light district. To the south of De Wallen is the old Jewish quarter of Waterlooplein. The medieval and colonial age canals of Amsterdam, known as grachten, embraces the heart of the city where homes have interesting gables. Beyond the Grachtengordel are the former working-class areas of Jordaan and de Pijp. The Museumplein with the city's major museums, the Vondelpark, a 19th-century park named after the Dutch writer Joost van den Vondel, as well as the Plantage neighbourhood, with the zoo, are also located outside the Grachtengordel. Several parts of the city and the surrounding urban area are polders. This can be recognised by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer and Watergraafsmeer. Canals The Amsterdam canal system is the result of conscious city planning. In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam, ruling lords of Amsterdam, whilst gracht means canal, so that the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal) and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and innermost canal, the Singel. The canals served for defense, water management and transport. The defenses took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental. Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly.

In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam, ruling lords of Amsterdam, whilst gracht means canal, so that the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal) and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and innermost canal, the Singel. The canals served for defense, water management and transport. The defenses took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental. Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly.

The eastern part of the concentric canal plan, covering the area between the Amstel river and the IJ bay, has never been implemented. In the following centuries, the land was used for parks, senior citizens' homes, theatres, other public facilities, and waterways without much planning. Over the years, several canals have been filled in, becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui. Expansion After the development of Amsterdam's canals in the 17th century, the city did not grow beyond its borders for two centuries. During the 19th century, Samuel Sarphati devised a plan based on the grandeur of Paris and London at that time. The plan envisaged the construction of new houses, public buildings and streets just outside the Grachtengordel. The main aim of the plan, however, was to improve public health. Although the plan did not expand the city, it did produce some of the largest public buildings to date, like the Paleis voor Volksvlijt. Following Sarphati, civil engineers Jacobus van Niftrik and Jan Kalff designed an entire ring of 19th-century neighbourhoods surrounding the city's centre, with the city preserving the ownership of all land outside the 17th-century limit, thus firmly controlling development. Most of these neighbourhoods became home to the working class. In response to overcrowding, two plans were designed at the beginning of the 20th century which were very different from anything Amsterdam had ever seen before: Plan Zuid (designed by the architect Berlage) and West. These plans involved the development of new neighbourhoods consisting of housing blocks for all social classes. After the Second World War, large new neighbourhoods were built in the western, southeastern, and northern parts of the city. These new neighbourhoods were built to relieve the city's shortage of living space and give people affordable houses with modern conveniences. The neighbourhoods consisted mainly of large housing blocks located among green spaces, connected to wide roads, making the neighbourhoods easily accessible by motor car. The western suburbs which were built in that period are collectively called the Westelijke Tuinsteden. The area to the southeast of the city built during the same period is known as the Bijlmer. Architecture Amsterdam has a rich architectural history. The oldest building in Amsterdam is the Oude Kerk (English: Old Church), at the heart of the Wallen, consecrated in 1306. The oldest wooden building is Het Houten Huys at the Begijnhof. It was constructed around 1425 and is one of only two existing wooden buildings. It is also one of the few examples of Gothic architecture in Amsterdam. The oldest stone building of the Netherlands, The Moriaan is built in 's-Hertogenbosch. In the 16th century, wooden buildings were razed and replaced with brick ones. During this period, many buildings were constructed in the architectural style of the Renaissance. Buildings of this period are very recognisable with their stepped gable façades, which is the common Dutch Renaissance style. Amsterdam quickly developed its own Renaissance architecture.

These buildings were built according to the principles of the architect Hendrick de Keyser. One of the most striking buildings designed by Hendrick de Keyser is the Westerkerk. In the 17th century baroque architecture became very popular, as it was elsewhere in Europe. This roughly coincided with Amsterdam's Golden Age. The leading architects of this style in Amsterdam were Jacob van Campen, Philips Vingboons and Daniel Stalpaert. Philip Vingboons designed splendid merchants' houses throughout the city. A famous building in baroque style in Amsterdam is the Royal Palace on Dam Square. Throughout the 18th century, Amsterdam was heavily influenced by French culture. This is reflected in the architecture of that period. Around 1815, architects broke with the baroque style and started building in different neo-styles. Most Gothic style buildings date from that era and are therefore said to be built in a neo-gothic style. At the end of the 19th century, the Jugendstil or Art Nouveau style became popular and many new buildings were constructed in this architectural style. Since Amsterdam expanded rapidly during this period, new buildings adjacent to the city centre were also built in this style. The houses in the vicinity of the Museum Square in Amsterdam Oud-Zuid are an example of Jugendstil. The last style that was popular in Amsterdam before the modern era was Art Deco. Amsterdam had its own version of the style, which was called the Amsterdamse School. Whole districts were built this style, such as the Rivierenbuurt. A notable feature of the façades of buildings designed in Amsterdamse School is that they are highly decorated and ornate, with oddly shaped windows and doors. The old city centre is the focal point of all the architectural styles before the end of the 19th century. Jugendstil and Georgian are mostly found outside the city's centre in the neighbourhoods built in the early 20th century, although there are also some striking examples of these styles in the city centre. Most historic buildings in the city centre and nearby are houses, such as the famous merchants' houses lining the canals. Parks and recreational areas Amsterdam has many parks, open spaces, and squares throughout the city. The Vondelpark, the largest park in the city, is located in the Oud-Zuid neighbourhood and is named after the 17th-century Amsterdam author Joost van den Vondel. Yearly, the park has around 10 million visitors. In the park is an open-air theatre, a playground and several horeca facilities. In the Zuid borough, is the Beatrixpark, named after Queen Beatrix. Between Amsterdam and Amstelveen is the Amsterdamse Bos ("Amsterdam Forest"), the largest recreational area in Amsterdam. Annually, almost 4.5 million people visit the park, which has a size of 1.000 hectares and is approximately three times the size of Central Park. The Amstelpark in the Zuid borough houses the Rieker windmill, which dates to 1636. Other parks include the Sarphatipark in the De Pijp neighbourhood, the Oosterpark in the Oost borough and the Westerpark in the Westerpark neighbourhood.

The city has three beaches: Nemo Beach, Citybeach "Het stenen hoofd" (Silodam) and Blijburg, all located in the Centrum borough. The city has many open squares (plein in Dutch). The namesake of the city as the site of the original dam, Dam Square, is the main city square and has the Royal Palace and National Monument. Museumplein hosts various museums, including the Rijksmuseum, Van Gogh Museum, and Stedelijk Museum. Other squares include Rembrandtplein, Muntplein, Nieuwmarkt, Leidseplein, Spui and Waterlooplein. Also, near to Amsterdam is the Nekkeveld estate conservation project. Economy Amsterdam is the financial and business capital of the Netherlands. According to the 2007 European Cities Monitor (ECM) – an annual location survey of Europe's leading companies carried out by global real estate consultant Cushman & Wakefield – Amsterdam is one of the top European cities in which to locate an international business, ranking fifth in the survey. with the survey determining London, Paris, Frankfurt and Barcelona as the four European cities surpassing Amsterdam in this regard. A substantial number of large corporations and banks' headquarters are located in the Amsterdam area, including: AkzoNobel, Heineken International, ING Group, ABN AMRO, TomTom, Delta Lloyd Group, Booking.com and Philips. Although many small offices remain along the historic canals, centrally based companies have increasingly relocated outside Amsterdam's city centre. Consequently, the Zuidas (English: South Axis) has become the new financial and legal hub of Amsterdam, with the country's five largest law firms and several subsidiaries of large consulting firms, such as Boston Consulting Group and Accenture, as well as the World Trade Centre (Amsterdam) located in the Zuidas district. In addition to the Zuidas, there are three smaller financial districts in Amsterdam: around Amsterdam Sloterdijk railway station. Where one can find the offices of several newspapers, such as De Telegraaf. as well as those of Deloitte, the Gemeentelijk Vervoerbedrijf (municipal public transport company), and the Dutch tax offices (Belastingdienst); around the Johan Cruyff Arena in Amsterdam Zuidoost, with the headquarters of ING Group; around the Amstel railway station in the Amsterdam-Oost district to the east of the historical city. Amsterdam's tallest building, the Rembrandt Tower, is located here. As are the headquarters of Philips, the Dutch multinational conglomerate. Amsterdam has been a leading city to reduce the use of raw materials and has created a plan to become a circular city by 2050. The adjoining municipality of Amstelveen is the location of KPMG International's global headquarters. Other non-Dutch companies have chosen to settle in communities surrounding Amsterdam since they allow freehold property ownership, whereas Amsterdam retains ground rent.

In 2014, the Port of Amsterdam had a cargo throughput of 97,4 million tons of cargo, which was mostly bulk cargo. Amsterdam has the biggest cruise port in the Netherlands with more than 150 cruise ships every year. In 2019, the new lock in IJmuiden opened; since then, the port has been able to grow to 125 million tonnes in capacity. Tourism Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 5.34 million international visitors annually, this is excluding the 16 million day-trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with 4 or 5 stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 85% in 2017, up from 78% in 2006. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city range from 12,000 to 65,000. De Wallen (red-light district) De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and best-known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of canals, streets, and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. In recent years, the city government has been closing and repurposing the famous red-light district windows in an effort to clean up the area and reduce the amount of party and sex tourism. Retail Shops in Amsterdam range from large high-end department stores such as De Bijenkorf founded in 1870 to small speciality shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops.

Tourism Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 5.34 million international visitors annually, this is excluding the 16 million day-trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with 4 or 5 stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 85% in 2017, up from 78% in 2006. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city range from 12,000 to 65,000. De Wallen (red-light district) De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and best-known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of canals, streets, and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. In recent years, the city government has been closing and repurposing the famous red-light district windows in an effort to clean up the area and reduce the amount of party and sex tourism. Retail Shops in Amsterdam range from large high-end department stores such as De Bijenkorf founded in 1870 to small speciality shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops.

However, as the Negen Straatjes are dominated by fashion stores, the Haarlemmerstraat and Haarlemmerdijk offer a wide variety of stores, just to name some specialities: candy and other food-related stores, lingerie, sneakers, wedding clothing, interior shops, books, Italian deli's, racing and mountain bikes, skatewear, etc. The city also features a large number of open-air markets such as the Albert Cuyp Market, Westerstraat-markt, Ten Katemarkt, and Dappermarkt. Some of these markets are held daily, like the Albert Cuypmarkt and the Dappermarkt. Others, like the Westerstraatmarkt, are held every week. Fashion Several fashion brands and designers are based in Amsterdam. Fashion designers include Iris van Herpen, Mart Visser, Viktor & Rolf, Marlies Dekkers and Frans Molenaar. Fashion models like Yfke Sturm, Doutzen Kroes and Kim Noorda started their careers in Amsterdam. Amsterdam has its garment centre in the World Fashion Center. Fashion photographers Inez van Lamsweerde and Vinoodh Matadin were born in Amsterdam. Culture During the later part of the 16th-century, Amsterdam's Rederijkerskamer (Chamber of rhetoric) organised contests between different Chambers in the reading of poetry and drama. In 1637, Schouwburg, the first theatre in Amsterdam was built, opening on 3 January 1638. The first ballet performances in the Netherlands were given in Schouwburg in 1642 with the Ballet of the Five Senses. In the 18th century, French theatre became popular. While Amsterdam was under the influence of German music in the 19th century there were few national opera productions; the Hollandse Opera of Amsterdam was built in 1888 for the specific purpose of promoting Dutch opera. In the 19th century, popular culture was centred on the Nes area in Amsterdam (mainly vaudeville and music-hall). An improved metronome was invented in 1812 by Dietrich Nikolaus Winkel. The Rijksmuseum (1885) and Stedelijk Museum (1895) were built and opened. In 1888, the Concertgebouworkest orchestra was established. With the 20th century came cinema, radio and television. Though most studios are located in Hilversum and Aalsmeer, Amsterdam's influence on programming is very strong. Many people who work in the television industry live in Amsterdam. Also, the headquarters of the Dutch SBS Broadcasting Group is located in Amsterdam. Museums The most important museums of Amsterdam are located on the Museumplein (Museum Square), located at the southwestern side of the Rijksmuseum. It was created in the last quarter of the 19th century on the grounds of the former World's fair. The northeastern part of the square is bordered by the large Rijksmuseum. In front of the Rijksmuseum on the square itself is a long, rectangular pond. This is transformed into an ice rink in winter. The northwestern part of the square is bordered by the Van Gogh Museum, House of Bols Cocktail & Genever Experience and Coster Diamonds. The southwestern border of the Museum Square is the Van Baerlestraat, which is a major thoroughfare in this part of Amsterdam. The Concertgebouw is located across this street from the square. To the southeast of the square are several large houses, one of which contains the American consulate.

A parking garage can be found underneath the square, as well as a supermarket. The Museumplein is covered almost entirely with a lawn, except for the northeastern part of the square which is covered with gravel. The current appearance of the square was realised in 1999, when the square was remodelled. The square itself is the most prominent site in Amsterdam for festivals and outdoor concerts, especially in the summer. Plans were made in 2008 to remodel the square again because many inhabitants of Amsterdam are not happy with its current appearance. The Rijksmuseum possesses the largest and most important collection of classical Dutch art. It opened in 1885. Its collection consists of nearly one million objects. The artist most associated with Amsterdam is Rembrandt, whose work, and the work of his pupils, is displayed in the Rijksmuseum.

The Stopera is the home base of Dutch National Opera, Dutch National Ballet and the Holland Symfonia. Muziekgebouw aan 't IJ is a concert hall, which is located in the IJ near the central station. Its concerts perform mostly modern classical music. Located adjacent to it, is the Bimhuis, a concert hall for improvised and Jazz music. Performing arts Amsterdam has three main theatre buildings. The Stadsschouwburg at the Leidseplein is the home base of Toneelgroep Amsterdam. The current building dates from 1894. Most plays are performed in the Grote Zaal (Great Hall). The normal program of events encompasses all sorts of theatrical forms. The Stadsschouwburg is currently being renovated and expanded. The third theatre space, to be operated jointly with next door Melkweg, will open in late 2009 or early 2010. The Dutch National Opera and Ballet (formerly known as Het Muziektheater), dating from 1986, is the principal opera house and home to Dutch National Opera and Dutch National Ballet. Royal Theatre Carré was built as a permanent circus theatre in 1887 and is currently mainly used for musicals, cabaret performances, and pop concerts. The recently re-opened DeLaMar Theater houses more commercial plays and musicals. A new theatre has also moved into the Amsterdam scene in 2014, joining other established venues: Theater Amsterdam is located in the west part of Amsterdam, on the Danzigerkade. It is housed in a modern building with a panoramic view over the harbour. The theatre is the first-ever purpose-built venue to showcase a single play entitled ANNE, the play based on Anne Frank's life. On the east side of town, there is a small theatre in a converted bathhouse, the Badhuistheater. The theatre often has English programming. The Netherlands has a tradition of cabaret or kleinkunst, which combines music, storytelling, commentary, theatre and comedy. Cabaret dates back to the 1930s and artists like Wim Kan, Wim Sonneveld and Toon Hermans were pioneers of this form of art in the Netherlands. In Amsterdam is the Kleinkunstacademie (English: Cabaret Academy) and Nederlied Kleinkunstkoor (English: Cabaret Choir). Contemporary popular artists are Youp van 't Hek, Freek de Jonge, Herman Finkers, Hans Teeuwen, Theo Maassen, Herman van Veen, Najib Amhali, Raoul Heertje, Jörgen Raymann, Brigitte Kaandorp and Comedytrain. The English spoken comedy scene was established with the founding of Boom Chicago in 1993. They have their own theatre at Leidseplein. Nightlife Amsterdam is famous for its vibrant and diverse nightlife.

The building contains three halls, Grote Zaal, Kleine Zaal, and Spiegelzaal. Some nine hundred concerts and other events per year take place in the Concertgebouw, for a public of over 700,000, making it one of the most-visited concert halls in the world. The opera house of Amsterdam is located adjacent to the city hall.

Nightlife Amsterdam is famous for its vibrant and diverse nightlife.

Amsterdam has many cafés (bars). They range from large and modern to small and cosy. The typical Bruine Kroeg (brown café) breathe a more old fashioned atmosphere with dimmed lights, candles, and somewhat older clientele. These brown cafés mostly offer a wide range of local and international artisanal beers. Most cafés have terraces in summertime. A common sight on the Leidseplein during summer is a square full of terraces packed with people drinking beer or wine. Many restaurants can be found in Amsterdam as well. Since Amsterdam is a multicultural city, a lot of different ethnic restaurants can be found. Restaurants range from being rather luxurious and expensive to being ordinary and affordable. Amsterdam also possesses many discothèques. The two main nightlife areas for tourists are the Leidseplein and the Rembrandtplein. The Paradiso, Melkweg and Sugar Factory are cultural centres, which turn into discothèques on some nights. Examples of discothèques near the Rembrandtplein are the Escape, Air, John Doe and Club Abe. Also noteworthy are Panama, Hotel Arena (East), TrouwAmsterdam and Studio 80. In recent years '24-hour' clubs opened their doors, most notably Radion De School, Shelter and Marktkantine. Bimhuis located near the Central Station, with its rich programming hosting the best in the field is considered one of the best jazz clubs in the world. The Reguliersdwarsstraat is the main street for the LGBT community and nightlife. Festivals In 2008, there were 140 festivals and events in Amsterdam. Famous festivals and events in Amsterdam include: Koningsdag (which was named Koninginnedag until the crowning of King Willem-Alexander in 2013) (King's Day – Queen's Day); the Holland Festival for the performing arts; the yearly Prinsengrachtconcert (classical concerto on the Prinsen canal) in August; the 'Stille Omgang' (a silent Roman Catholic evening procession held every March); Amsterdam Gay Pride; The Cannabis Cup; and the Uitmarkt. On Koningsdag—that is held each year on 27 April—hundreds of thousands of people travel to Amsterdam to celebrate with the city's residents. The entire city becomes overcrowded with people buying products from the freemarket, or visiting one of the many music concerts. The yearly Holland Festival attracts international artists and visitors from all over Europe. Amsterdam Gay Pride is a yearly local LGBT parade of boats in Amsterdam's canals, held on the first Saturday in August. The annual Uitmarkt is a three-day cultural event at the start of the cultural season in late August. It offers previews of many different artists, such as musicians and poets, who perform on podia. Sports Amsterdam is home of the Eredivisie football club AFC Ajax. The stadium Johan Cruyff Arena is the home of Ajax. It is located in the south-east of the city next to the new Amsterdam Bijlmer ArenA railway station. Before moving to their current location in 1996, Ajax played their regular matches in the now demolished De Meer Stadion in the eastern part of the city or in the Olympic Stadium.

The Olympic Stadium built for the occasion has been completely restored and is now used for cultural and sporting events, such as the Amsterdam Marathon. In 1920, Amsterdam assisted in hosting some of the sailing events for the Summer Olympics held in neighbouring Antwerp, Belgium by hosting events at Buiten IJ. The city holds the Dam to Dam Run, a race from Amsterdam to Zaandam, as well as the Amsterdam Marathon. The ice hockey team Amstel Tijgers play in the Jaap Eden ice rink. The team competes in the Dutch ice hockey premier league. Speed skating championships have been held on the 400-meter lane of this ice rink. Amsterdam holds two American football franchises: the Amsterdam Crusaders and the Amsterdam Panthers. The Amsterdam Pirates baseball team competes in the Dutch Major League. There are three field hockey teams: Amsterdam, Pinoké and Hurley, who play their matches around the Wagener Stadium in the nearby city of Amstelveen. The basketball team MyGuide Amsterdam competes in the Dutch premier division and play their games in the Sporthallen Zuid. There is one rugby club in Amsterdam, which also hosts sports training classes such as RTC (Rugby Talenten Centrum or Rugby Talent Centre) and the National Rugby stadium. Since 1999, the city of Amsterdam honours the best sportsmen and women at the Amsterdam Sports Awards. Boxer Raymond Joval and field hockey midfielder Carole Thate were the first to receive the awards, in 1999. Amsterdam hosted the World Gymnaestrada in 1991 and will do so again in 2023. Politics The city of Amsterdam is a municipality under the Dutch Municipalities Act. It is governed by a directly elected municipal council, a municipal executive board and a mayor. Since 1981, the municipality of Amsterdam has gradually been divided into semi-autonomous boroughs, called stadsdelen or 'districts'. Over time, a total of 15 boroughs were created. In May 2010, under a major reform, the number of Amsterdam boroughs was reduced to eight: Amsterdam-Centrum covering the city centre including the canal belt, Amsterdam-Noord consisting of the neighbourhoods north of the IJ lake, Amsterdam-Oost in the east, Amsterdam-Zuid in the south, Amsterdam-West in the west, Amsterdam Nieuw-West in the far west, Amsterdam Zuidoost in the southeast, and Westpoort covering the Port of Amsterdam area. City government As with all Dutch municipalities, Amsterdam is governed by a directly elected municipal council, a municipal executive board and a government appointed mayor (burgemeester). The mayor is a member of the municipal executive board, but also has individual responsibilities in maintaining public order. On 27 June 2018, Femke Halsema (former member of House of Representatives for GroenLinks from 1998 to 2011) was appointed as the first woman to be Mayor of Amsterdam by the King's Commissioner of North Holland for a six-year term after being nominated by the Amsterdam municipal council and began serving a six-year term on 12 July 2018. She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017.

She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017.

After the 2014 municipal council elections, a governing majority of D66, VVD and SP was formed – the first coalition without the Labour Party since World War II. Next to the Mayor, the municipal executive board consists of eight wethouders ('alderpersons') appointed by the municipal council: four D66 alderpersons, two VVD alderpersons and two SP alderpersons. On 18 September 2017, it was announced by Eberhard van der Laan in an open letter to Amsterdam citizens that Kajsa Ollongren would take up his office as acting Mayor of Amsterdam with immediate effect due to ill health. Ollongren was succeeded as acting Mayor by Eric van der Burg on 26 October 2017 and by Jozias van Aartsen on 4 December 2017. Unlike most other Dutch municipalities, Amsterdam is subdivided into eight boroughs, called stadsdelen or 'districts', a system that was implemented gradually in the 1980s to improve local governance. The boroughs are responsible for many activities that had previously been run by the central city. In 2010, the number of Amsterdam boroughs reached fifteen. Fourteen of those had their own district council (deelraad), elected by a popular vote. The fifteenth, Westpoort, covers the harbour of Amsterdam and had very few residents. Therefore, it was governed by the central municipal council. Under the borough system, municipal decisions are made at borough level, except for those affairs pertaining to the whole city such as major infrastructure projects, which are the jurisdiction of the central municipal authorities. In 2010, the borough system was restructured, in which many smaller boroughs merged into larger boroughs. In 2014, under a reform of the Dutch Municipalities Act, the Amsterdam boroughs lost much of their autonomous status, as their district councils were abolished. The municipal council of Amsterdam voted to maintain the borough system by replacing the district councils with smaller, but still directly elected district committees (bestuurscommissies). Under a municipal ordinance, the new district committees were granted responsibilities through delegation of regulatory and executive powers by the central municipal council. Metropolitan area "Amsterdam" is usually understood to refer to the municipality of Amsterdam. Colloquially, some areas within the municipality, such as the town of Durgerdam, may not be considered part of Amsterdam. Statistics Netherlands uses three other definitions of Amsterdam: metropolitan agglomeration Amsterdam (Grootstedelijke Agglomeratie Amsterdam, not to be confused with Grootstedelijk Gebied Amsterdam, a synonym of Groot Amsterdam), Greater Amsterdam (Groot Amsterdam, a COROP region) and the urban region Amsterdam (Stadsgewest Amsterdam). The Amsterdam Department for Research and Statistics uses a fourth conurbation, namely the Stadsregio Amsterdam ('City Region of Amsterdam'). The city region is similar to Greater Amsterdam but includes the municipalities of Zaanstad and Wormerland. It excludes Graft-De Rijp. The smallest of these areas is the municipality of Amsterdam with a population of 802,938 in 2013. The conurbation had a population of 1,096,042 in 2013. It includes the municipalities of Zaanstad, Wormerland, Oostzaan, Diemen and Amstelveen only, as well as the municipality of Amsterdam.

Greater Amsterdam includes 15 municipalities, and had a population of 1,293,208 in 2013. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Amsterdam Metropolitan Area (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerland, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants. Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibilities include regional spatial planning and the metropolitan public transport concessions. National capital Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam"). Previous versions of the constitution only mentioned "the city of Amsterdam" ("de stad Amsterdam"). For a royal investiture, therefore, the States General of the Netherlands (the Dutch Parliament) meets for a ceremonial joint session in Amsterdam. The ceremony traditionally takes place at the Nieuwe Kerk on Dam Square, immediately after the former monarch has signed the act of abdication at the nearby Royal Palace of Amsterdam. Normally, however, the Parliament sits in The Hague, the city which has historically been the seat of the Dutch government, the Dutch monarchy, and the Dutch supreme court. Foreign embassies are also located in The Hague. Symbols The coat of arms of Amsterdam is composed of several historical elements. First and centre are three St Andrew's crosses, aligned in a vertical band on the city's shield (although Amsterdam's patron saint was Saint Nicholas). These St Andrew's crosses can also be found on the city shields of neighbours Amstelveen and Ouder-Amstel. This part of the coat of arms is the basis of the flag of Amsterdam, flown by the city government, but also as civil ensign for ships registered in Amsterdam. Second is the Imperial Crown of Austria. In 1489, out of gratitude for services and loans, Maximilian I awarded Amsterdam the right to adorn its coat of arms with the king's crown. Then, in 1508, this was replaced with Maximilian's imperial crown when he was crowned Holy Roman Emperor. In the early years of the 17th century, Maximilian's crown in Amsterdam's coat of arms was again replaced, this time with the crown of Emperor Rudolph II, a crown that became the Imperial Crown of Austria. The lions date from the late 16th century, when city and province became part of the Republic of the Seven United Netherlands. Last came the city's official motto: Heldhaftig, Vastberaden, Barmhartig ("Heroic, Determined, Merciful"), bestowed on the city in 1947 by Queen Wilhelmina, in recognition of the city's bravery during the Second World War.

Greater Amsterdam includes 15 municipalities, and had a population of 1,293,208 in 2013. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Amsterdam Metropolitan Area (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerland, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants. Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibilities include regional spatial planning and the metropolitan public transport concessions. National capital Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam").

Transport Metro, tram and bus Currently, there are sixteen tram routes and five metro routes. All are operated by municipal public transport operator Gemeentelijk Vervoerbedrijf (GVB), which also runs the city bus network. Four fare-free GVB ferries carry pedestrians and cyclists across the IJ lake to the borough of Amsterdam-Noord, and two fare-charging ferries run east and west along the harbour. There are also privately operated water taxis, a water bus, a boat sharing operation, electric rental boats and canal cruises, that transport people along Amsterdam's waterways. Regional buses, and some suburban buses, are operated by Connexxion and EBS. International coach services are provided by Eurolines from Amsterdam Amstel railway station, IDBUS from Amsterdam Sloterdijk railway station, and Megabus from the Zuiderzeeweg in the east of the city. In order to facilitate easier transport to the centre of Amsterdam, the city has various P+R Locations where people can park their car at an affordable price and transfer to one of the numerous public transport lines. Car Amsterdam was intended in 1932 to be the hub, a kind of Kilometre Zero, of the highway system of the Netherlands, with freeways numbered One to Eight planned to originate from the city. The outbreak of the Second World War and shifting priorities led to the current situation, where only roads A1, A2, and A4 originate from Amsterdam according to the original plan. The A3 to Rotterdam was cancelled in 1970 in order to conserve the Groene Hart. Road A8, leading north to Zaandam and the A10 Ringroad were opened between 1968 and 1974. Besides the A1, A2, A4 and A8, several freeways, such as the A7 and A6, carry traffic mainly bound for Amsterdam. The A10 ringroad surrounding the city connects Amsterdam with the Dutch national network of freeways. Interchanges on the A10 allow cars to enter the city by transferring to one of the 18 city roads, numbered S101 through to S118. These city roads are regional roads without grade separation, and sometimes without a central reservation. Most are accessible by cyclists. The S100 Centrumring is a smaller ringroad circumnavigating the city's centre. In the city centre, driving a car is discouraged. Parking fees are expensive, and many streets are closed to cars or are one-way. The local government sponsors carsharing and carpooling initiatives such as Autodelen and Meerijden.nu. The local government has also started removing parking spaces in the city, with the goal of removing 10,000 spaces (roughly 1,500 per year) by 2025 National rail Amsterdam is served by ten stations of the Nederlandse Spoorwegen (Dutch Railways). Five are intercity stops: Sloterdijk, Zuid, Amstel, Bijlmer ArenA and Amsterdam Centraal. The stations for local services are: Lelylaan, RAI, Holendrecht, Muiderpoort and Science Park. Amsterdam Centraal is also an international railway station. From the station there are regular services to destinations such as Austria, Belarus, Belgium, Czechia, Denmark, France, Germany, Hungary, Poland, Russia, Switzerland and the United Kingdom.

Among these trains are international trains of the Nederlandse Spoorwegen (Amsterdam-Berlin), the Eurostar (Amsterdam-Brussels-London), Thalys (Amsterdam-Brussels-Paris/Lille), and Intercity-Express (Amsterdam–Cologne–Frankfurt). Airport Amsterdam Airport Schiphol is less than 20 minutes by train from Amsterdam Centraal station and is served by domestic and international intercity trains, such as Thalys, Eurostar and Intercity Brussel. Schiphol is the largest airport in the Netherlands, the third-largest in Europe, and the 14th-largest in the world in terms of passengers. It handles over 68 million passengers per year and is the home base of four airlines, KLM, Transavia, Martinair and Arkefly. , Schiphol was the fifth busiest airport in the world measured by international passenger numbers. This airport is 4 meters below sea level. Although Schiphol is internationally known as Amsterdam Schiphol Airport it actually lies in the neighbouring municipality of Haarlemmermeer, southwest of the city. Cycling Amsterdam is one of the most bicycle-friendly large cities in the world and is a centre of bicycle culture with good facilities for cyclists such as bike paths and bike racks, and several guarded bike storage garages (fietsenstalling) which can be used. According to the most recent figures published by Central Bureau of Statistics (CBS), in 2015 the 442.693 households (850.000 residents) in Amsterdam together owned 847.000 bicycles – 1.91 bicycle per household. Previously, wildly different figures were arrived at using a Wisdom of the crowd approach. Theft is widespreadin 2011, about 83,000 bicycles were stolen in Amsterdam. Bicycles are used by all socio-economic groups because of their convenience, Amsterdam's small size, the of bike paths, the flat terrain, and the inconvenience of driving an automobile. Education Amsterdam has two universities: the University of Amsterdam (Universiteit van Amsterdam, UvA), and the Vrije Universiteit Amsterdam (VU). Other institutions for higher education include an art school – Gerrit Rietveld Academie, a university of applied sciences – the Hogeschool van Amsterdam, and the Amsterdamse Hogeschool voor de Kunsten. Amsterdam's International Institute of Social History is one of the world's largest documentary and research institutions concerning social history, and especially the history of the labour movement. Amsterdam's Hortus Botanicus, founded in the early 17th century, is one of the oldest botanical gardens in the world, with many old and rare specimens, among them the coffee plant that served as the parent for the entire coffee culture in Central and South America. There are over 200 primary schools in Amsterdam. Some of these primary schools base their teachings on particular pedagogic theories like the various Montessori schools. The biggest Montessori high school in Amsterdam is the Montessori Lyceum Amsterdam. Many schools, however, are based on religion. This used to be primarily Roman Catholicism and various Protestant denominations, but with the influx of Muslim immigrants, there has been a rise in the number of Islamic schools. Jewish schools can be found in the southern suburbs of Amsterdam.

Amsterdam is noted for having five independent grammar schools (Dutch: gymnasia), the Vossius Gymnasium, Barlaeus Gymnasium, St. Ignatius Gymnasium, Het 4e Gymnasium and the Cygnus Gymnasium where a classical curriculum including Latin and classical Greek is taught. Though believed until recently by many to be an anachronistic and elitist concept that would soon die out, the gymnasia have recently experienced a revival, leading to the formation of a fourth and fifth grammar school in which the three aforementioned schools participate. Most secondary schools in Amsterdam offer a variety of different levels of education in the same school. The city also has various colleges ranging from art and design to politics and economics which are mostly also available for students coming from other countries. Schools for foreign nationals in Amsterdam include the Amsterdam International Community School, British School of Amsterdam, Albert Einstein International School Amsterdam, Lycée Vincent van Gogh La Haye-Amsterdam primary campus (French school), International School of Amsterdam, and the Japanese School of Amsterdam. Notable people Media Amsterdam is a prominent centre for national and international media. Some locally based newspapers include Het Parool, a national daily paper; De Telegraaf, the largest Dutch daily newspaper; the daily newspapers Trouw, de Volkskrant and NRC Handelsblad; De Groene Amsterdammer, a weekly newspaper; the free newspapers Metro and The Holland Times (printed in English). Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV-stations SBS 6, Net 5 and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum, south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies. In 2012, the music video of Far East Movement, 'Live My Life', was filmed in various parts of Amsterdam. Also, several movies were filmed in Amsterdam, such as James Bond's Diamonds Are Forever, Ocean's Twelve, Girl with a Pearl Earring and The Hitman's Bodyguard. Amsterdam is also featured in John Green's book The Fault in Our Stars, which has been made into a film as well that partly takes place in Amsterdam. Housing From the late 1960s onwards many buildings in Amsterdam have been squatted both for housing and for using as social centres. A number of these squats have legalised and become well known, such as OCCII, OT301, Paradiso and Vrankrijk.

Museum of Work The Museum of Work (Arbetets museum) is a museum located in Norrköping, Sweden. The museum is located in the Strykjärn (Clothes iron), a former weaving mill in the old industrial area on the Motala ström river in the city centre of Norrköping. The former textile factory Holmens Bruk (sv) operated in the building from 1917 to 1962. The museum documents work and everyday life by collecting personal stories about people's professional lives from both the past and the present. The museum's archive contain material from memory collections and documentation projects. Since 2009, the museum also houses the EWK — Center for Political Illustration Art, which is based on work of the satirist Ewert Karlsson (1918 — 2004). For decades he was frequently published in the Swedish tabloid, Aftonbladet. Overview The museum is a national central museum with the task of preserving and telling about work and everyday life. It has, among other things, exhibitions on the terms and conditions of the work and the history of the industrial society. The museum is also known to highlight gender perspective in their exhibitions. The work museum documents work and everyday life by collecting personal stories, including people's professional life from both the past and present. In the museum's archive, there is a rich material of memory collections and documentation projects — over 2600 interviews, stories and photodocumentations have been collected since the museum opened. The museum is also a support for the country's approximately 1,500 working life museums that are old workplaces preserved to convey their history. Exhibitions The Museum of Work shows exhibitions going on over several years, but also shorter exhibitions — including several photo exhibitions on themes that can be linked to work and everyday life. The history of Alva The history of Alva Karlsson is the only exhibition in the museum that is permanent. The exhibition connects to the museum's building and its history as part of the textile industry in Norrköping. Alva worked as a rollers between the years 1927 — 1962. Industriland One of the museum long-term exhibitions is Industriland — when Sweden became modern, the exhibition was in 2007 — 2013 and consisted of an ongoing bond with various objects that were somehow significant both for working life and everyday during the period 1930 — 1980. The exhibition also consisted of presentations of the working life museums in Sweden and a number of rooms with themes such as: leisure, world, living and consumption. Framtidsland (Future country) In 2014, the exhibition was inaugurated that takes by where Industriland ends: Future country. It is an exhibition that investigates what a sustainable society is will be part of the museum's exhibitions until 2019. The exhibition consists of materials that are designed based on conversations between young people and researchers around Sweden. The exhibition addresses themes such as work, environment and everyday life. A tour version of the exhibition is given in the locations Falun, Kristianstad and Örebro.

Audi Audi AG () (commonly referred to as Audi) is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. As a subsidiary of its parent company, the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, going back to the early 20th century and the initial enterprises (Horch and the Audiwerke) founded by engineer August Horch; and two other manufacturers (DKW and Wanderer), leading to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. The company name is based on the Latin translation of the surname of the founder, August Horch. , meaning "listen" in German, becomes in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is , meaning "Being Ahead through Technology". Audi, along with fellow German marques BMW and Mercedes-Benz, is among the best-selling luxury automobile brands in the world. History Birth of the company and its name Automobile company Wanderer was originally established in 1885, later becoming a branch of Audi AG. Another company, NSU, which also later merged into Audi, was founded during this time, and later supplied the chassis for Gottlieb Daimler's four-wheeler. On 14 November 1899, August Horch (1868–1951) established the company A. Horch & Cie. in the Ehrenfeld district of Cologne. In 1902, he moved with his company to Reichenbach im Vogtland. On 10 May 1904, he founded the August Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony). After troubles with Horch chief financial officer, August Horch left Motorwagenwerke and founded in Zwickau on 16 July 1909, his second company, the August Horch Automobilwerke GmbH. His former partners sued him for trademark infringement. The German Reichsgericht (Supreme Court) in Leipzig, eventually determined that the Horch brand belonged to his former company. Since August Horch was prohibited from using "Horch" as a trade name in his new car business, he called a meeting with close business friends, Paul and Franz Fikentscher from Zwickau. At the apartment of Franz Fikentscher, they discussed how to come up with a new name for the company. During this meeting, Franz's son was quietly studying Latin in a corner of the room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars... wouldn't it be a good idea to call it audi instead of horch?" "Horch!" in German means "Hark!" or "hear", which is "Audi" in the singular imperative form of "audire" – "to listen" – in Latin.

"Horch!" in German means "Hark!" or "hear", which is "Audi" in the singular imperative form of "audire" – "to listen" – in Latin.

The idea was enthusiastically accepted by everyone attending the meeting. On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau) was entered in the company's register of Zwickau registration court. The first Audi automobile, the Audi Type A 10/ Sport-Phaeton, was produced in the same year, followed by the successor Type B 10/28PS in the same year. Audi started with a 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924. August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive. Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer when driving on the right. The merger of the four companies under the logo of four rings In August 1928, Jørgen Rasmussen, the owner of Dampf-Kraft-Wagen (DKW), acquired the majority of shares in Audiwerke AG. In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker, including the manufacturing equipment for 8-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, 6-cylinder and 4-cylinder (the "four" with a Peugeot engine) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork. In 1932, Audi merged with Horch, DKW, and Wanderer, to form Auto Union AG, Chemnitz. It was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a power train shared with the Wanderer, but turned 180 degrees, so that the drive shaft faced the front. Before World War II, Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. However, this badge was used only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch- or Wanderer-built engines. Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of the German car market, while Audi held only 0.1%. After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades.

After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades.

Post-World War II Like most German manufacturing, at the onset of World War II the Auto Union plants were retooled for military production, and were a target for allied bombing during the war which left them damaged. Overrun by the Soviet Army in 1945, on the orders of the Soviet Union military administration the factories were dismantled as part of war reparations. Following this, the company's entire assets were expropriated without compensation. On 17 August 1948, Auto Union AG of Chemnitz was deleted from the commercial register. These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") or AWZ (in English: Automobile Works Zwickau). With no prospect of continuing production in Soviet-controlled East Germany, Auto Union executives began the process of relocating what was left of the company to West Germany. A site was chosen in Ingolstadt, Bavaria, to start a spare parts operation in late 1945, which would eventually serve as the headquarters of the reformed Auto Union in 1949. The former Audi factory in Zwickau restarted assembly of the pre-war models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to the West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines. The Zwickau plant manufactured the infamous Trabant until 1991, when it came under Volkswagen control—effectively bringing it under the same umbrella as Audi since 1945. New Auto Union unit A new West German headquartered Auto Union was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid. The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines. This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, consisting of an extensive complex of formerly military buildings which was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig. It was only ten years later, after the company had attracted an investor, when funds became available for construction of major car plant at the Ingolstadt head office site. In 1958, in response to pressure from Friedrich Flick, then the company's largest single shareholder, Daimler-Benz took an 87% holding in the Auto Union company, and this was increased to a 100% holding in 1959.

However, small two-stroke cars were not the focus of Daimler-Benz's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap. In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 was fitted with a four-stroke engine and a facelift for the car's front and rear. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi". Later developments of the model were named after their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972. Initially, Volkswagen was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant – to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that Volkswagen had no long-term ambition for the Audi brand, Auto Union engineers under the leadership of Ludwig Kraus developed the first Audi 100 in secret, without Nordhoff's knowledge. When presented with a finished prototype, Nordhoff was so impressed he authorised the car for production, which when launched in 1968, went on to be a huge success. With this, the resurrection of the Audi brand was now complete, this being followed by the first generation Audi 80 in 1972, which would in turn provide a template for VW's new front-wheel-drive water-cooled range which debuted from the mid-1970s onward.

However, small two-stroke cars were not the focus of Daimler-Benz's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap. In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 was fitted with a four-stroke engine and a facelift for the car's front and rear. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi".

In 1969, Auto Union merged with NSU, based in Neckarsulm, near Stuttgart. In the 1950s, NSU had been the world's largest manufacturer of motorcycles, but had moved on to produce small cars like the NSU Prinz, the TT and TTS versions of which are still popular as vintage race cars. NSU then focused on new rotary engines based on the ideas of Felix Wankel. In 1967, the new NSU Ro 80 was a car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the "quattro GmbH" (from November 2016 "Audi Sport GmbH"), a subsidiary responsible for development and production of Audi high-performance models: the R8 and the RS model range. Modern era The new merged company was incorporated on 1 January 1969 and was known as Audi NSU Auto Union AG, with its headquarters at NSU's Neckarsulm plant, and saw the emergence of Audi as a separate brand for the first time since the pre-war era. Volkswagen introduced the Audi brand to the United States for the 1970 model year. That same year, the mid-sized car that NSU had been working on, the K70, originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80, was instead launched as a Volkswagen. After the launch of the Audi 100 of 1968, the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) followed in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car. Ultimately, the Audi 80 and 100 (progenitors of the A4 and A6, respectively) became the company's biggest sellers, whilst little investment was made in the fading NSU range; the Prinz models were dropped in 1973 whilst the fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, and by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher-end models. The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger was accepted to develop the four-wheel drive technology in Volkswagen's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the "Audi Quattro", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through a centre differential.

Commonly referred to as the "Ur-Quattro" (the "Ur-" prefix is a German augmentative used, in this case, to mean "original" and is also applied to the first generation of Audi's S4 and S6 Sport Saloons, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved the viability of all-wheel-drive racecars, and the Audi name became associated with advances in automotive technology. In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG. At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH, were formed to own and manage the historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations. In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied the low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option.) In 1987, Audi put forward a new and very elegant Audi 90, which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface. In the early part of the 21st century, Audi set forth on a German racetrack to claim and maintain several world records, such as top speed endurance. This effort was in-line with the company's heritage from the 1930s racing era Silver Arrows. Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW. This began with the release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet. By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100, the turbocharged Audi 200 and the Audi V8. There was also a coupé version of the 80/90 with both four- and five-cylinder engines. Although the five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine. This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in saloon, coupé and convertible body styles. The five-cylinder was soon dropped as a major engine choice; however, a turbocharged version remained.

The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro. It was fitted to the Audi Coupé, named the S2, and also to the Audi 100 body, and named the S4. These two models were the beginning of the mass-produced S series of performance cars. Audi 5000 unintended acceleration allegations Sales in the United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power. A 60 Minutes report aired 23 November 1986, featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering a problem when the brake pedal was pushed. Subsequent investigation revealed that 60 Minutes had engineered the failure – fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission. Audi contended, prior to findings by outside investigators, that the problems were caused by driver error, specifically pedal misapplication. Subsequently, the National Highway Traffic Safety Administration (NHTSA) concluded that the majority of unintended acceleration cases, including all the ones that prompted the 60 Minutes report, were caused by driver error such as confusion of pedals. CBS did not acknowledge the test results of involved government agencies, but did acknowledge the similar results of another study. In a review study published in 2012, NHTSA summarized its past findings about the Audi unintended acceleration problems: "Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident." This summary is consistent with the conclusions of NHTSA's most technical analysis at the time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver. The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada." With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park.

The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada." With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park.

A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed. Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years, – with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed the affected models – with the 5000 becoming the 100 and 200 in 1989 – and reached the same sales levels again only by model year 2000. A 2010 BusinessWeek article – outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls – noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and remains contested in Chicago's Cook County after appeals at the Illinois state and U.S. federal levels. Model introductions In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminium construction. Produced from 1999 to 2005, the Audi A2 was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium space frame, which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement. The next major model change came in 1995 when the Audi A4 replaced the Audi 80. The new nomenclature scheme was applied to the Audi 100 to become the Audi A6 (with a minor facelift). This also meant the S4 became the S6 and a new S4 was introduced in the A4 body. The S2 was discontinued. The Audi Cabriolet continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new A3 hatchback model (sharing the Volkswagen Golf Mk4's platform) was introduced to the range in 1996, and the radical Audi TT coupé and roadster were debuted in 1998 based on the same underpinnings. The engines available throughout the range were now a 1.4 L, 1.6 L and 1.8 L four-cylinder, 1.8 L four-cylinder turbo, 2.6 L and 2.8 L V6, 2.2 L turbo-charged five-cylinder and the 4.2 L V8 engine. The V6s were replaced by new 2.4 L and 2.8 L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7 L V8 and 6.0 L W12 engine for the A8.

Audi AG today Audi's sales grew strongly in the 2000s, with deliveries to customers increasing from 653,000 in 2000 to 1,003,000 in 2008. The largest sales increases came from Eastern Europe (+19.3%), Africa (+17.2%) and the Middle East (+58.5%). China in particular has become a key market, representing 108,000 out of 705,000 cars delivered in the first three quarters of 2009. One factor for its popularity in China is that Audis have become the car of choice for purchase by the Chinese government for officials, and purchases by the government are responsible for 20% of its sales in China. As of late 2009, Audi's operating profit of €1.17 billion ($1.85 billion) made it the biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5 billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses. May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel. In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone. Audi manufactures vehicles in seven plants around the world, some of which are shared with other VW Group marques although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants. Audi's two principal assembly plants are: Ingolstadt, opened by Auto Union in 1964 (A3, A4, A5, Q5) Neckarsulm, acquired from NSU in 1969 (A4, A6, A7, A8, R8, and all RS variants) Outside of Germany, Audi produces vehicles at: Aurangabad, India, since 2006 Bratislava, Slovakia, shared with Volkswagen, SEAT, Škoda and Porsche (Q7 and Q8) Brussels, Belgium, acquired from Volkswagen in 2007 (e-tron) Changchun, China, since 1995 Győr, Hungary (TT and some A3 variants) Jakarta, Indonesia, since 2011 Martorell, Spain, shared with SEAT and Volkswagen (A1) San José Chiapa, Mexico (2nd gen Q5) In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla, Mexico. This plant became operative in 2016 and produces the second generation Q5. From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, which was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand. In January 2014, Audi, along with the Wireless Power Consortium, operated a booth which demonstrated a phone compartment using the Qi open interface standard at the Consumer Electronics Show (CES). In May, most of the Audi dealers in the UK falsely claimed that the Audi A7, A8, and R8 were Euro NCAP safety tested, all achieving five out of five stars. In fact none were tested. In 2015, Audi admitted that at least 2.1 million Audi cars had been involved in the Volkswagen emissions testing scandal in which software installed in the cars manipulated emissions data to fool regulators and allow the cars to pollute at higher than government-mandated levels.

The A1, A3, A4, A5, A6, TT, Q3 and Q5 models were implicated in the scandal. Audi promised to quickly find a technical solution and upgrade the cars so they can function within emissions regulations. Ulrich Hackenberg, the head of research and development at Audi, was suspended in relation to the scandal. Despite widespread media coverage about the scandal through the month of September, Audi reported that U.S. sales for the month had increased by 16.2%. Audi's parent company Volkswagen announced on 18 June 2018 that Audi chief executive Rupert Stadler had been arrested. In November 2015, the U.S. Environmental Protection Agency implicated the 3-liter diesel engine versions of the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and the Q5 as further models that had emissions regulation defeat-device software installed. Thus, these models emitted nitrogen oxide at up to nine times the legal limit when the car detected that it was not hooked up to emissions testing equipment. In November 2016, Audi expressed an intention to establish an assembly factory in Pakistan, with the company's local partner acquiring land for a plant in Korangi Creek Industrial Park in Karachi. Approval of the plan would lead to an investment of $30 million in the new plant. Audi planned to cut 9,500 jobs in Germany starting from 2020 till 2025 to fund electric vehicles and digital working. In February 2020, Volkswagen AG announced that it plans to take over all Audi shares it does not own (totalling 0.36%) via a squeeze-out according to German stock corporation law, thus making Audi a fully owned subsidiary of the Volkswagen Group. This change took effect from 16 November 2020, when Audi became a wholly owned subsidiary of the Volkswagen Group. In January 2021, Audi announced that it is planning to sell 1 million vehicles in China in 2023, comparing to 726,000 vehicles in 2020. Technology Audi AI Audi AI is a driver assist feature offered by Audi. The company's stated intent is to offer fully autonomous driving at a future time, acknowledging that legal, regulatory and technical hurdles must be overcome to achieve this goal. On 4 June 2017, Audi stated that its new A8 will be fully self-driving for speeds up to 60 km/h using its Audi AI. Contrary to other cars, the driver will not have to do safety checks such as touching the steering wheel every 15 seconds to use this feature. The Audi A8 will therefore be the first production car to reach level 3 autonomous driving, meaning that the driver can safely turn their attention away from driving tasks, e.g. the driver can text or watch a movie. Audi will also be the first manufacturer to use a 3D Lidar system in addition to cameras and ultrasonic sensors for their AI. Bodyshells Audi produces 100% galvanised cars to prevent corrosion, and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975.

Bodyshells Audi produces 100% galvanised cars to prevent corrosion, and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975.

Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust). Space frame Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop. The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs. Drivetrains Layout For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution. In all its post Volkswagen-era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive).

The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs. Drivetrains Layout For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution. In all its post Volkswagen-era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive).

Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust). Space frame Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop. The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs.

To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s.

Audi has recently applied the quattro badge to models such as the A3 and TT which do not use the Torsen-based system as in prior years with a mechanical center differential, but with the Haldex Traction electro-mechanical clutch AWD system. Engines Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day. In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power. For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a "WR12") is created by forming two imaginary narrow-angle 15° VR6 engines at an angle of 72°, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants. The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with . Fuel Stratified Injection New models of the A3, A4, A6 and A8 have been introduced, with the ageing 1.8-litre engine now having been replaced by new Fuel Stratified Injection (FSI) engines. Nearly every petroleum burning model in the range now incorporates this fuel-saving technology. Direct-Shift Gearbox In 2003, Volkswagen introduced the Direct-Shift Gearbox (DSG), a type of dual-clutch transmission. It is a type of automatic transmission, drivable like a conventional torque converter automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electro-hydraulically controlled clutches instead of a torque converter.

This is implemented in some VW Golfs, Audi A3, Audi A4 and TT models where DSG is called S-Tronic. LED daytime running lights Beginning in 2005, Audi has implemented white LED technology as daytime running lights (DRL) in their products. The distinctive shape of the DRLs has become a trademark of sorts. LEDs were first introduced on the Audi A8 W12, the world's first production car to have LED DRLs, and have since spread throughout the entire model range. The LEDs are present on some Audi billboards. Since 2010, Audi has also offered the LED technology in low- and high-beam headlights. Multi Media Interface Starting with the 2003 Audi A8, Audi has used a centralised control interface for its on-board infotainment systems, called Multi Media Interface (MMI). It is essentially a rotating control knob and 'segment' buttons – designed to control all in-car entertainment devices (radio, CD changer, iPod, TV tuner), satellite navigation, heating and ventilation, and other car controls with a screen. The availability of MMI has gradually filtered down the Audi lineup, and following its introduction on the third generation A3 in 2011, MMI is now available across the entire range. It has been generally well received, as it requires less menu-surfing with its segment buttons around a central knob, along with 'main function' direct access buttons – with shortcuts to the radio or phone functions. The colour screen is mounted on the upright dashboard, and on the A4 (new), A5, A6, A8, and Q7, the controls are mounted horizontally. Synthetic fuels Audi has assisted with technology to produce synthetic diesel from water and carbon dioxide. Audi calls the synthetic diesel E-diesel. It is also working on synthetic gasoline (which it calls E-gasoline). Logistics Audi uses scanning gloves for parts registration during assembly, and automatic robots to transfer cars from factory to rail cars. Models Current model range The following tables list Audi production vehicles that are sold as of 2018: S and RS models Electric vehicles Audi is planning an alliance with the Japanese electronics giant Sanyo to develop a pilot hybrid electric project for the Volkswagen Group. The alliance could result in Sanyo batteries and other electronic components being used in future models of the Volkswagen Group. Concept electric vehicles unveiled to date include the Audi A1 Sportback Concept, Audi A4 TDI Concept E, and the fully electric Audi e-tron Concept Supercar. Self-driving cars In December 2018, Audi announced to invest 14 billion Euro ($15.9 billion) in e-mobility, self-driving cars. Production figures Data from 1998 to 2010. Figures for different body types/versions of models have been merged to create overall figures for each model. Motorsport Audi has competed in various forms of motorsports. Audi's tradition in motorsport began with their former company Auto Union in the 1930s. In the 1990s, Audi found success in the Touring and Super Touring categories of motor racing after success in circuit racing in North America.

Rallying In 1980, Audi released the Quattro, a four-wheel drive (4WD) turbocharged car that went on to win rallies and races worldwide. It is considered one of the most significant rally cars of all time, because it was one of the first to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. Many critics doubted the viability of four-wheel drive racers, thinking them to be too heavy and complex, yet the Quattro was to become a successful car. It led its first rally before going off the road, however, the rally world had been served notice 4WD was the future. The Quattro went on to achieve much success in the World Rally Championship. It won the 1983 (Hannu Mikkola) and the 1984 (Stig Blomqvist) drivers' titles, and brought Audi the manufacturers' title in 1982 and 1984. In 1984, Audi launched the short-wheelbase Sport Quattro which dominated rally races in Monte Carlo and Sweden, with Audi taking all podium places, but succumbed to problems further into WRC contention. In 1985, after another season mired in mediocre finishes, Walter Röhrl finished the season in his Sport Quattro S1, and helped place Audi second in the manufacturers' points. Audi also received rally honours in the Hong Kong to Beijing rally in that same year. Michèle Mouton, the only female driver to win a round of the World Rally Championship and a driver for Audi, took the Sport Quattro S1, now simply called the "S1", and raced in the Pikes Peak International Hill Climb. The climb race pits a driver and car to drive to the summit of the Pikes Peak mountain in Colorado, and in 1985, Michèle Mouton set a new record of 11:25.39, and being the first woman to set a Pikes Peak record. In 1986, Audi formally left international rally racing following an accident in Portugal involving driver Joaquim Santos in his Ford RS200. Santos swerved to avoid hitting spectators in the road, and left the track into the crowd of spectators on the side, killing three and injuring 30. Bobby Unser used an Audi in that same year to claim a new record for the Pikes Peak Hill Climb at 11:09.22. In 1987, Walter Röhrl claimed the title for Audi setting a new Pikes Peak International Hill Climb record of 10:47.85 in his Audi S1, which he had retired from the WRC two years earlier. The Audi S1 employed Audi's time-tested inline-five-cylinder turbocharged engine, with the final version generating . The engine was mated to a six-speed gearbox and ran on Audi's famous four-wheel drive system. All of Audi's top drivers drove this car; Hannu Mikkola, Stig Blomqvist, Walter Röhrl and Michèle Mouton. This Audi S1 started the range of Audi 'S' cars, which now represents an increased level of sports-performance equipment within the mainstream Audi model range.

In the United States As Audi moved away from rallying and into circuit racing, they chose to move first into America with the Trans-Am in 1988. In 1989, Audi moved to International Motor Sports Association (IMSA) GTO with the Audi 90, however as they avoided the two major endurance events (Daytona and Sebring) despite winning on a regular basis, they would lose out on the title. Touring cars In 1990, having completed their objective to market cars in North America, Audi returned to Europe, turning first to the Deutsche Tourenwagen Meisterschaft (DTM) series with the Audi V8, and then in 1993, being unwilling to build cars for the new formula, they turned their attention to the fast-growing Super Touring series, which are a series of national championships. Audi first entered in the French Supertourisme and Italian Superturismo. In the following year, Audi would switch to the German Super Tourenwagen Cup (known as STW), and then to British Touring Car Championship (BTCC) the year after that. The Fédération Internationale de l'Automobile (FIA), having difficulty regulating the quattro four-wheel drive system, and the impact it had on the competitors, would eventually ban all four-wheel drive cars from competing in the series in 1998, but by then, Audi switched all their works efforts to sports car racing. By 2000, Audi would still compete in the US with their RS4 for the SCCA Speed World GT Challenge, through dealer/team Champion Racing competing against Corvettes, Vipers, and smaller BMWs (where it is one of the few series to permit 4WD cars). In 2003, Champion Racing entered an RS6. Once again, the quattro four-wheel drive was superior, and Champion Audi won the championship. They returned in 2004 to defend their title, but a newcomer, Cadillac with the new Omega Chassis CTS-V, gave them a run for their money. After four victories in a row, the Audis were sanctioned with several negative changes that deeply affected the car's performance. Namely, added ballast weights, and Champion Audi deciding to go with different tyres, and reducing the boost pressure of the turbocharger. In 2004, after years of competing with the TT-R in the revitalised DTM series, with privateer team Abt Racing/Christian Abt taking the 2002 title with Laurent Aïello, Audi returned as a full factory effort to touring car racing by entering two factory-supported Joest Racing A4 DTM cars. 24 Hours of Le Mans Audi began racing prototype sportscars in 1999, debuting at the Le Mans 24 hour. Two car concepts were developed and raced in their first season - the Audi R8R (open-cockpit 'roadster' prototype) and the Audi R8C (closed-cockpit 'coupé' GT-prototype). The R8R scored a credible podium on its racing debut at Le Mans and was the concept which Audi continued to develop into the 2000 season due to favourable rules for open-cockpit prototypes. However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999.

In the United States As Audi moved away from rallying and into circuit racing, they chose to move first into America with the Trans-Am in 1988. In 1989, Audi moved to International Motor Sports Association (IMSA) GTO with the Audi 90, however as they avoided the two major endurance events (Daytona and Sebring) despite winning on a regular basis, they would lose out on the title. Touring cars In 1990, having completed their objective to market cars in North America, Audi returned to Europe, turning first to the Deutsche Tourenwagen Meisterschaft (DTM) series with the Audi V8, and then in 1993, being unwilling to build cars for the new formula, they turned their attention to the fast-growing Super Touring series, which are a series of national championships. Audi first entered in the French Supertourisme and Italian Superturismo. In the following year, Audi would switch to the German Super Tourenwagen Cup (known as STW), and then to British Touring Car Championship (BTCC) the year after that. The Fédération Internationale de l'Automobile (FIA), having difficulty regulating the quattro four-wheel drive system, and the impact it had on the competitors, would eventually ban all four-wheel drive cars from competing in the series in 1998, but by then, Audi switched all their works efforts to sports car racing. By 2000, Audi would still compete in the US with their RS4 for the SCCA Speed World GT Challenge, through dealer/team Champion Racing competing against Corvettes, Vipers, and smaller BMWs (where it is one of the few series to permit 4WD cars). In 2003, Champion Racing entered an RS6. Once again, the quattro four-wheel drive was superior, and Champion Audi won the championship. They returned in 2004 to defend their title, but a newcomer, Cadillac with the new Omega Chassis CTS-V, gave them a run for their money.

However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999.

The factory-supported Joest Racing team won at Le Mans three times in a row with the Audi R8 (2000–2002), as well as winning every race in the American Le Mans Series in its first year. Audi also sold the car to customer teams such as Champion Racing. In 2003, two Bentley Speed 8s, with engines designed by Audi, and driven by Joest drivers loaned to the fellow Volkswagen Group company, competed in the GTP class, and finished the race in the top two positions, while the Champion Racing R8 finished third overall, and first in the LMP900 class. Audi returned to the winner's podium at the 2004 race, with the top three finishers all driving R8s: Audi Sport Japan Team Goh finished first, Audi Sport UK Veloqx second, and Champion Racing third. At the 2005 24 Hours of Le Mans, Champion Racing entered two R8s, along with an R8 from the Audi PlayStation Team Oreca. The R8s (which were built to old LMP900 regulations) received a narrower air inlet restrictor, reducing power, and an additional of weight compared to the newer LMP1 chassis. On average, the R8s were about 2–3 seconds off pace compared to the Pescarolo–Judd. But with a team of excellent drivers and experience, both Champion R8s were able to take first and third, while the Oreca team took fourth. The Champion team was also the first American team to win Le Mans since the Gulf Ford GTs in 1967. This also ends the long era of the R8; however, its replacement for 2006, called the Audi R10 TDI, was unveiled on 13 December 2005. The R10 TDI employed many new and innovative features, the most notable being the twin-turbocharged direct injection diesel engine. It was first raced in the 2006 12 Hours of Sebring as a race-test in preparation for the 2006 24 Hours of Le Mans, which it later went on to win. Audi had a win in the first diesel sports car at 12 Hours of Sebring (the car was developed with a Diesel engine due to ACO regulations that favor diesel engines). As well as winning the 24 Hours of Le Mans in 2006, the R10 TDI beat the Peugeot 908 HDi FAP in , and in , (however Peugeot won the 24h in 2009) with a podium clean-sweep (all four 908 entries retired) while breaking a distance record (set by the Porsche 917K of Martini Racing in ), in with the R15 TDI Plus. Audi's sports car racing success would continue with the Audi R18's victory at the 2011 24 Hours of Le Mans. Audi Sport Team Joest's Benoît Tréluyer earned Audi their first pole position in five years while the team's sister car locked out the front row. Early accidents eliminated two of Audi's three entries, but the sole remaining Audi R18 TDI of Tréluyer, Marcel Fässler, and André Lotterer held off the trio of Peugeot 908s to claim victory by a margin of 13.8 seconds.

Results American Le Mans Series Audi entered a factory racing team run by Joest Racing into the American Le Mans Series under the Audi Sport North America name in 2000. This was a successful operation with the team winning on its debut in the series at the 2000 12 Hours of Sebring. Factory-backed Audi R8s were the dominant car in ALMS taking 25 victories between 2000 and the end of the 2002 season. In 2003, Audi sold customer cars to Champion Racing as well as continuing to race the factory Audi Sport North America team. Champion Racing won many races as a private team running Audi R8s and eventually replaced Team Joest as the Audi Sport North America between 2006 and 2008.

The factory team Audi Sport UK won races and the championship in the 2004 season but Audi was unable to match their sweeping success of Audi Sport North America in the American Le Mans Series, partly due to the arrival of a factory competitor in LMP1, Peugeot. The French manufacturer's 908 HDi FAP became the car to beat in the series from 2008 onwards with 20 LMP wins. However, Audi were able to secure the championship in 2008 even though Peugeot scored more race victories in the season.

Results Formula E Audi provide factory support to Abt Sportsline in the FIA Formula E Championship, The team competed under the title of Audi Sport Abt Formula E Team in the inaugural 2014-15 Formula E season. On 13 February 2014 the team announced its driver line up as Daniel Abt and World Endurance Championship driver Lucas di Grassi. Formula One Audi has been linked to Formula One in recent years but has always resisted due to the company's opinion that it is not relevant to road cars, but hybrid power unit technology has been adopted into the sport, swaying the company's view and encouraging research into the program by former Ferrari team principal Stefano Domenicali. Marketing Branding The Audi emblem is four overlapping rings that represent the four marques of Auto Union. The Audi emblem symbolises the amalgamation of Audi with DKW, Horch and Wanderer: the first ring from the left represents Audi, the second represents DKW, third is Horch, and the fourth and last ring Wanderer. The design is popularly believed to have been the idea of Klaus von Oertzen, the director of sales at Wanderer – when Berlin was chosen as the host city for the 1936 Summer Olympics and that a form of the Olympic logo symbolized the newly established Auto Union's desire to succeed. Somewhat ironically, the International Olympic Committee later sued Audi in the International Trademark Court in 1995, where they lost. The original "Audi" script, with the distinctive slanted tails on the "A" and "d" was created for the historic Audi company in 1920 by the famous graphic designer Lucian Bernhard, and was resurrected when Volkswagen revived the brand in 1965. Following the demise of NSU in 1977, less prominence was given to the four rings, in preference to the "Audi" script encased within a black (later red) ellipse, and was commonly displayed next to the Volkswagen roundel when the two brands shared a dealer network under the V.A.G banner. The ellipse (known as the Audi Oval) was phased out after 1994, when Audi formed its own independent dealer network, and prominence was given back to the four rings – at the same time Audi Sans (a derivative of Univers) was adopted as the font for all marketing materials, corporate communications and was also used in the vehicles themselves. As part of Audi's centennial celebration in 2009, the company updated the logo, changing the font to left-aligned Audi Type, and altering the shading for the overlapping rings. The revised logo was designed by Rayan Abdullah. Audi developed a Corporate Sound concept, with Audi Sound Studio designed for producing the Corporate Sound.

Audi also developed Sound Branding Toolkit including certain instruments, sound themes, rhythm and car sounds which all are supposed to reflect the AUDI sound character. Audi started using a beating heart sound trademark beginning in 1996. An updated heartbeat sound logo, developed by agencies KLANGERFINDER GmbH & Co KG of Stuttgart and S12 GmbH of Munich, was first used in 2010 in an Audi A8 commercial with the slogan The Art of Progress. Slogans Audi's corporate tagline is , meaning "Progress through Technology". The German-language tagline is used in many European countries, including the United Kingdom (but not in Italy, where is used), and in other markets, such as Latin America, Oceania, Africa and parts of Asia including Japan. Originally, the American tagline was Innovation through technology, but in Canada Vorsprung durch Technik was used. Since 2007, Audi has used the slogan Truth in Engineering in the U.S. However, since the Audi emissions testing scandal came to light in September 2015, this slogan was lambasted for being discordant with reality. In fact, just hours after disgraced Volkswagen CEO Martin Winterkorn admitted to cheating on emissions data, an advertisement during the 2015 Primetime Emmy Awards promoted Audi's latest advances in low emissions technology with Kermit the Frog stating, "It's not that easy being green." Vorsprung durch Technik was first used in English-language advertising after Sir John Hegarty of the Bartle Bogle Hegarty advertising agency visited the Audi factory in 1982. In the original British television commercials, the phrase was voiced by Geoffrey Palmer. After its repeated use in advertising campaigns, the phrase found its way into popular culture, including the British comedy Only Fools and Horses, the U2 song "Zooropa" and the Blur song "Parklife". Similar-sounding phrases have also been used, including as the punchline for a joke in the movie Lock, Stock, and Two Smoking Barrels and in the British TV series Peep Show. Typography Audi Sans (based on Univers Extended) was originally created in 1997 by Ole Schäfer for MetaDesign. MetaDesign was later commissioned for a new corporate typeface called Audi Type, designed by Paul van der Laan and Pieter van Rosmalen of Bold Monday. The font began to appear in Audi's 2009 products and marketing materials. Sponsorships Audi is a strong partner of different kinds of sports. In football, long partnerships exist between Audi and domestic clubs including Bayern Munich, Hamburger SV, 1.

Audi e-tron The next phase of technology Audi is developing is the e-tron electric drive powertrain system. They have shown several concept cars , each with different levels of size and performance.

The original e-tron concept shown at the 2009 Frankfurt motor show is based on the platform of the R8 and has been scheduled for limited production. Power is provided by electric motors at all four wheels. The second concept was shown at the 2010 Detroit Motor Show. Power is provided by two electric motors at the rear axle. This concept is also considered to be the direction for a future mid-engined gas-powered 2-seat performance coupe. The Audi A1 e-tron concept, based on the Audi A1 production model, is a hybrid vehicle with a range extending Wankel rotary engine to provide power after the initial charge of the battery is depleted. It is the only concept of the three to have range-extending capability. The car is powered through the front wheels, always using electric power. It is all set to be displayed at the Auto Expo 2012 in New Delhi, India, from 5 January. Powered by a 1.4 litre engine, and can cover a distance up to 54 km s on a single charge. The e-tron was also shown in the 2013 blockbuster film Iron Man 3 and was driven by Tony Stark (Iron Man). In video games Audi has supported the European version of PlayStation Home, the PlayStation 3's online community-based service, by releasing a dedicated Home space. Audi is the first carmaker to develop such a space for Home. On 17 December 2009, Audi released two spaces; the Audi Home Terminal and the Audi Vertical Run. The Audi Home Terminal features an Audi TV channel delivering video content, an Internet Browser feature, and a view of a city. The Audi Vertical Run is where users can access the mini-game Vertical Run, a futuristic mini-game featuring Audi's e-tron concept. Players collect energy and race for the highest possible speeds and the fastest players earn a place in the Audi apartments located in a large tower in the centre of the Audi Space. In both the Home Terminal and Vertical Run spaces, there are teleports where users can teleport back and forth between the two spaces. Audi had stated that additional content would be added in 2010. On 31 March 2015 Sony shutdown the PlayStation Home service rendering all content for it inaccessible.

Aircraft An aircraft is a vehicle or machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air balloons developed in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras: Pioneers of flight, from the earliest experiments to 1914. First World War, 1914 to 1918. Aviation between the World Wars, 1918 to 1939. Second World War, 1939 to 1945. Postwar era, also called the Jet Age, 1945 to the present day. Methods of lift Lighter than air – aerostats Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large cells or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, it adds up to the same weight as the air that the craft displaces. Small hot-air balloons, called sky lanterns, were first invented in ancient China prior to the 3rd century BC and used primarily in cultural celebrations, and were only the second type of aircraft to fly, the first being kites, which were first invented in ancient China over two thousand years ago. (See Han Dynasty) A balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs — usually fixed-wing. In 1919, Frederick Handley Page was reported as referring to "ships of the air," with smaller passenger types as "Air yachts." In the 1930s, large intercontinental flying boats were also sometimes referred to as "ships of the air" or "flying-ships". — though none had yet been built. The advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by a rigid outer framework and separate aerodynamic skin surrounding the gas bags, were produced, the Zeppelins being the largest and most famous.

Huge powered aerostats, characterized by a rigid outer framework and separate aerodynamic skin surrounding the gas bags, were produced, the Zeppelins being the largest and most famous.

There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, so "airship" came to be synonymous with these aircraft. Then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a "balloon" is an unpowered aerostat and an "airship" is a powered one. A powered, steerable aerostat is called a dirigible. Sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps. During World War II, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon. The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered. Heavier-than-air – aerodynes Heavier-than-air aircraft, such as airplanes, must find some way to push air or gas downwards so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term. There are two ways to produce dynamic upthrust — aerodynamic lift, and powered lift in the form of engine thrust. Aerodynamic lift involving wings is the most common, with fixed-wing aircraft being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called rotary wings. A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, air must flow over the wing and generate lift. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed, or rotary. With powered lift, the aircraft directs its engine thrust vertically downward. V/STOL aircraft, such as the Harrier Jump Jet and Lockheed Martin F-35B take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. A pure rocket is not usually regarded as an aerodyne because it does not depend on the air for its lift (and can even fly into space); however, many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles that obtain aerodynamic lift at very high speed due to airflow over their bodies are a marginal case. Fixed-wing The forerunner of the fixed-wing aircraft is the kite. Whereas a fixed-wing aircraft relies on its forward speed to create airflow over the wings, a kite is tethered to the ground and relies on the wind blowing over its wings to provide lift. Kites were the first kind of aircraft to fly and were invented in China around 500 BC.

The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered. Heavier-than-air – aerodynes Heavier-than-air aircraft, such as airplanes, must find some way to push air or gas downwards so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term. There are two ways to produce dynamic upthrust — aerodynamic lift, and powered lift in the form of engine thrust. Aerodynamic lift involving wings is the most common, with fixed-wing aircraft being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called rotary wings. A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, air must flow over the wing and generate lift. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed, or rotary. With powered lift, the aircraft directs its engine thrust vertically downward. V/STOL aircraft, such as the Harrier Jump Jet and Lockheed Martin F-35B take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. A pure rocket is not usually regarded as an aerodyne because it does not depend on the air for its lift (and can even fly into space); however, many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles that obtain aerodynamic lift at very high speed due to airflow over their bodies are a marginal case. Fixed-wing The forerunner of the fixed-wing aircraft is the kite. Whereas a fixed-wing aircraft relies on its forward speed to create airflow over the wings, a kite is tethered to the ground and relies on the wind blowing over its wings to provide lift. Kites were the first kind of aircraft to fly and were invented in China around 500 BC.

There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, so "airship" came to be synonymous with these aircraft. Then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a "balloon" is an unpowered aerostat and an "airship" is a powered one. A powered, steerable aerostat is called a dirigible. Sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps. During World War II, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon.

Kites were the first kind of aircraft to fly and were invented in China around 500 BC.

Much aerodynamic research was done with kites before test aircraft, wind tunnels, and computer modelling programs became available. The first heavier-than-air craft capable of controlled free-flight were gliders. A glider designed by George Cayley carried out the first true manned, controlled flight in 1853. The practical, powered, fixed-wing aircraft (the airplane or aeroplane) was invented by Wilbur and Orville Wright. Besides the method of propulsion, fixed-wing aircraft are in general characterized by their wing configuration. The most important wing characteristics are: Number of wings — monoplane, biplane, etc. Wing support — Braced or cantilever, rigid, or flexible. Wing planform — including aspect ratio, angle of sweep, and any variations along the span (including the important class of delta wings). Location of the horizontal stabilizer, if any. Dihedral angle — positive, zero, or negative (anhedral). A variable geometry aircraft can change its wing configuration during flight. A flying wing has no fuselage, though it may have small blisters or pods. The opposite of this is a lifting body, which has no wings, though it may have small stabilizing and control surfaces. Wing-in-ground-effect vehicles are generally not considered aircraft. They "fly" efficiently close to the surface of the ground or water, like conventional aircraft during takeoff. An example is the Russian ekranoplan nicknamed the "Caspian Sea Monster". Man-powered aircraft also rely on ground effect to remain airborne with minimal pilot power, but this is only because they are so underpowered—in fact, the airframe is capable of flying higher. Rotorcraft Rotorcraft, or rotary-wing aircraft, use a spinning rotor with aerofoil section blades (a rotary wing) to provide lift. Types include helicopters, autogyros, and various hybrids such as gyrodynes and compound rotorcraft. Helicopters have a rotor turned by an engine-driven shaft. The rotor pushes air downward to create lift. By tilting the rotor forward, the downward flow is tilted backward, producing thrust for forward flight. Some helicopters have more than one rotor and a few have rotors turned by gas jets at the tips. Autogyros have unpowered rotors, with a separate power plant to provide thrust. The rotor is tilted backward. As the autogyro moves forward, air blows upward across the rotor, making it spin. This spinning increases the speed of airflow over the rotor, to provide lift. Rotor kites are unpowered autogyros, which are towed to give them forward speed or tethered to a static anchor in high-wind for kited flight. Cyclogyros rotate their wings about a horizontal axis. Compound rotorcraft have wings that provide some or all of the lift in forward flight. They are nowadays classified as powered lift types and not as rotorcraft. Tiltrotor aircraft (such as the Bell Boeing V-22 Osprey), tiltwing, tail-sitter, and coleopter aircraft have their rotors/propellers horizontal for vertical flight and vertical for forward flight. Other methods of lift A lifting body is an aircraft body shaped to produce lift. If there are any wings, they are too small to provide significant lift and are used only for stability and control.

Other methods of lift A lifting body is an aircraft body shaped to produce lift. If there are any wings, they are too small to provide significant lift and are used only for stability and control.

Lifting bodies are not efficient: they suffer from high drag, and must also travel at high speed to generate enough lift to fly. Many of the research prototypes, such as the Martin Marietta X-24, which led up to the Space Shuttle, were lifting bodies, though the Space Shuttle is not, and some supersonic missiles obtain lift from the airflow over a tubular body. Powered lift types rely on engine-derived lift for vertical takeoff and landing (VTOL). Most types transition to fixed-wing lift for horizontal flight. Classes of powered lift types include VTOL jet aircraft (such as the Harrier Jump Jet) and tiltrotors, such as the Bell Boeing V-22 Osprey, among others. A few experimental designs rely entirely on engine thrust to provide lift throughout the whole flight, including personal fan-lift hover platforms and jetpacks. VTOL research designs include the Rolls-Royce Thrust Measuring Rig. The Flettner airplane uses a rotating cylinder in place of a fixed wing, obtaining lift from the Magnus effect. The ornithopter obtains thrust by flapping its wings. Size and speed extremes Size The smallest aircraft are toys/recreational items, and nano aircraft.

Take-off may be by launching forward and downward from a high location, or by pulling into the air on a tow-line, either by a ground-based winch or vehicle, or by a powered "tug" aircraft. For a glider to maintain its forward air speed and lift, it must descend in relation to the air (but not necessarily in relation to the ground). Many gliders can "soar", i.e., gain height from updrafts such as thermal currents. The first practical, controllable example was designed and built by the British scientist and pioneer George Cayley, whom many recognise as the first aeronautical engineer. Common examples of gliders are sailplanes, hang gliders and paragliders. Balloons drift with the wind, though normally the pilot can control the altitude, either by heating the air or by releasing ballast, giving some directional control (since the wind direction changes with altitude). A wing-shaped hybrid balloon can glide directionally when rising or falling; but a spherically shaped balloon does not have such directional control. Kites are aircraft that are tethered to the ground or other object (fixed or mobile) that maintains tension in the tether or kite line; they rely on virtual or real wind blowing over and under them to generate lift and drag. Kytoons are balloon-kite hybrids that are shaped and tethered to obtain kiting deflections, and can be lighter-than-air, neutrally buoyant, or heavier-than-air. Powered aircraft Powered aircraft have one or more onboard sources of mechanical power, typically aircraft engines although rubber and manpower have also been used. Most aircraft engines are either lightweight reciprocating engines or gas turbines. Engine fuel is stored in tanks, usually in the wings but larger aircraft also have additional fuel tanks in the fuselage. Propeller aircraft Propeller aircraft use one or more propellers (airscrews) to create thrust in a forward direction. The propeller is usually mounted in front of the power source in tractor configuration but can be mounted behind in pusher configuration. Variations of propeller layout include contra-rotating propellers and ducted fans. Many kinds of power plant have been used to drive propellers. Early airships used man power or steam engines. The more practical internal combustion piston engine was used for virtually all fixed-wing aircraft until World War II and is still used in many smaller aircraft. Some types use turbine engines to drive a propeller in the form of a turboprop or propfan. Human-powered flight has been achieved, but has not become a practical means of transport. Unmanned aircraft and models have also used power sources such as electric motors and rubber bands. Jet aircraft Jet aircraft use airbreathing jet engines, which take in air, burn fuel with it in a combustion chamber, and accelerate the exhaust rearwards to provide thrust. Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner.

Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner.

Those with no rotating turbomachinery include the pulsejet and ramjet. These mechanically simple engines produce no thrust when stationary, so the aircraft must be launched to flying speed using a catapult, like the V-1 flying bomb, or a rocket, for example. Other engine types include the motorjet and the dual-cycle Pratt & Whitney J58. Compared to engines using propellers, jet engines can provide much higher thrust, higher speeds and, above about , greater efficiency. They are also much more fuel-efficient than rockets. As a consequence nearly all large, high-speed or high-altitude aircraft use jet engines. Rotorcraft Some rotorcraft, such as helicopters, have a powered rotary wing or rotor, where the rotor disc can be angled slightly forward so that a proportion of its lift is directed forwards. The rotor may, like a propeller, be powered by a variety of methods such as a piston engine or turbine. Experiments have also used jet nozzles at the rotor blade tips. Other types of powered aircraft Rocket-powered aircraft have occasionally been experimented with, and the Messerschmitt Me 163 Komet fighter even saw action in the Second World War. Since then, they have been restricted to research aircraft, such as the North American X-15, which traveled up into space where air-breathing engines cannot work (rockets carry their own oxidant). Rockets have more often been used as a supplement to the main power plant, typically for the rocket-assisted take off of heavily loaded aircraft, but also to provide high-speed dash capability in some hybrid designs such as the Saunders-Roe SR.53. The ornithopter obtains thrust by flapping its wings. It has found practical use in a model hawk used to freeze prey animals into stillness so that they can be captured, and in toy birds. Design and construction Aircraft are designed according to many factors such as customer and manufacturer demand, safety protocols and physical and economic constraints. For many types of aircraft the design process is regulated by national airworthiness authorities. The key parts of an aircraft are generally divided into three categories: The structure comprises the main load-bearing elements and associated equipment. The propulsion system (if it is powered) comprises the power source and associated equipment, as described above. The avionics comprise the control, navigation and communication systems, usually electrical in nature. Structure The approach to structural design varies widely between different types of aircraft. Some, such as paragliders, comprise only flexible materials that act in tension and rely on aerodynamic pressure to hold their shape. A balloon similarly relies on internal gas pressure, but may have a rigid basket or gondola slung below it to carry its payload. Early aircraft, including airships, often employed flexible doped aircraft fabric covering to give a reasonably smooth aeroshell stretched over a rigid frame. Later aircraft employed semi-monocoque techniques, where the skin of the aircraft is stiff enough to share much of the flight loads. In a true monocoque design there is no internal structure left.

With the recent emphasis on sustainability hemp has picked up some attention, having a way smaller carbon foot print and 10 times stronger than steel, hemp could become the standard of manufacturing in the future. The key structural parts of an aircraft depend on what type it is. Aerostats Lighter-than-air types are characterised by one or more gasbags, typically with a supporting structure of flexible cables or a rigid framework called its hull. Other elements such as engines or a gondola may also be attached to the supporting structure. Aerodynes Heavier-than-air types are characterised by one or more wings and a central fuselage. The fuselage typically also carries a tail or empennage for stability and control, and an undercarriage for takeoff and landing. Engines may be located on the fuselage or wings. On a fixed-wing aircraft the wings are rigidly attached to the fuselage, while on a rotorcraft the wings are attached to a rotating vertical shaft. Smaller designs sometimes use flexible materials for part or all of the structure, held in place either by a rigid frame or by air pressure. The fixed parts of the structure comprise the airframe. Avionics The avionics comprise the aircraft flight control systems and related equipment, including the cockpit instrumentation, navigation, radar, monitoring, and communications systems. Flight characteristics Flight envelope The flight envelope of an aircraft refers to its approved design capabilities in terms of airspeed, load factor and altitude. The term can also refer to other assessments of aircraft performance such as maneuverability. When an aircraft is abused, for instance by diving it at too-high a speed, it is said to be flown outside the envelope, something considered foolhardy since it has been taken beyond the design limits which have been established by the manufacturer. Going beyond the envelope may have a known outcome such as flutter or entry to a non-recoverable spin (possible reasons for the boundary). Range The range is the distance an aircraft can fly between takeoff and landing, as limited by the time it can remain airborne. For a powered aircraft the time limit is determined by the fuel load and rate of consumption. For an unpowered aircraft, the maximum flight time is limited by factors such as weather conditions and pilot endurance. Many aircraft types are restricted to daylight hours, while balloons are limited by their supply of lifting gas. The range can be seen as the average ground speed multiplied by the maximum time in the air. The Airbus A350-900ULR is now the longest range airliner. Flight dynamics Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation around three axes which pass through the vehicle's center of gravity, known as pitch, roll, and yaw. Roll is a rotation about the longitudinal axis (equivalent to the rolling or heeling of a ship) giving an up-down movement of the wing tips measured by the roll or bank angle.

Roll is a rotation about the longitudinal axis (equivalent to the rolling or heeling of a ship) giving an up-down movement of the wing tips measured by the roll or bank angle.

Pitch is a rotation about the sideways horizontal axis giving an up-down movement of the aircraft nose measured by the angle of attack. Yaw is a rotation about the vertical axis giving a side-to-side movement of the nose known as sideslip. Flight dynamics is concerned with the stability and control of an aircraft's rotation about each of these axes. Stability An aircraft that is unstable tends to diverge from its intended flight path and so is difficult to fly. A very stable aircraft tends to stay on its flight path and is difficult to maneuver. Therefore, it is important for any design to achieve the desired degree of stability. Since the widespread use of digital computers, it is increasingly common for designs to be inherently unstable and rely on computerised control systems to provide artificial stability. A fixed wing is typically unstable in pitch, roll, and yaw. Pitch and yaw stabilities of conventional fixed wing designs require horizontal and vertical stabilisers, which act similarly to the feathers on an arrow. These stabilizing surfaces allow equilibrium of aerodynamic forces and to stabilise the flight dynamics of pitch and yaw. They are usually mounted on the tail section (empennage), although in the canard layout, the main aft wing replaces the canard foreplane as pitch stabilizer. Tandem wing and tailless aircraft rely on the same general rule to achieve stability, the aft surface being the stabilising one. A rotary wing is typically unstable in yaw, requiring a vertical stabiliser. A balloon is typically very stable in pitch and roll due to the way the payload is slung underneath the center of lift. Control Flight control surfaces enable the pilot to control an aircraft's flight attitude and are usually part of the wing or mounted on, or integral with, the associated stabilizing surface. Their development was a critical advance in the history of aircraft, which had until that point been uncontrollable in flight. Aerospace engineers develop control systems for a vehicle's orientation (attitude) about its center of mass. The control systems include actuators, which exert forces in various directions, and generate rotational forces or moments about the aerodynamic center of the aircraft, and thus rotate the aircraft in pitch, roll, or yaw. For example, a pitching moment is a vertical force applied at a distance forward or aft from the aerodynamic center of the aircraft, causing the aircraft to pitch up or down. Control systems are also sometimes used to increase or decrease drag, for example to slow the aircraft to a safe speed for landing. The two main aerodynamic forces acting on any aircraft are lift supporting it in the air and drag opposing its motion. Control surfaces or other techniques may also be used to affect these forces directly, without inducing any rotation. Impacts of aircraft use Aircraft permit long distance, high speed travel and may be a more fuel efficient mode of transportation in some circumstances. Aircraft have environmental and climate impacts beyond fuel efficiency considerations, however.

They are also relatively noisy compared to other forms of travel and high altitude aircraft generate contrails, which experimental evidence suggests may alter weather patterns. Uses for aircraft Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model. Military A military aircraft is any aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: Combat aircraft are aircraft designed to destroy enemy equipment using its own armament. Combat aircraft divide broadly into fighters and bombers, with several in-between types, such as fighter-bombers and attack aircraft, including attack helicopters. Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. Non-combat roles include search and rescue, reconnaissance, observation, transport, training, and aerial refueling. These aircraft are often variants of civil aircraft. Most military aircraft are powered heavier-than-air types. Other types, such as gliders and balloons, have also been used as military aircraft; for example, balloons were used for observation during the American Civil War and World War I, and military gliders were used during World War II to land troops. Civil Civil aircraft divide into commercial and general types, however there are some overlaps. Commercial aircraft include types designed for scheduled and charter airline flights, carrying passengers, mail and other cargo. The larger passenger-carrying types are the airliners, the largest of which are wide-body aircraft. Some of the smaller types are also used in general aviation, and some of the larger types are used as VIP aircraft. General aviation is a catch-all covering other kinds of private (where the pilot is not paid for time or expenses) and commercial use, and involving a wide range of aircraft types such as business jets (bizjets), trainers, homebuilt, gliders, warbirds and hot air balloons to name a few. The vast majority of aircraft today are general aviation types. Experimental An experimental aircraft is one that has not been fully proven in flight, or that carries a Special Airworthiness Certificate, called an Experimental Certificate in United States parlance. This often implies that the aircraft is testing new aerospace technologies, though the term also refers to amateur-built and kit-built aircraft, many of which are based on proven designs. Model A model aircraft is a small unmanned type made to fly for fun, for static display, for aerodynamic research or for other purposes. A scale model is a replica of some larger design.

They are also relatively noisy compared to other forms of travel and high altitude aircraft generate contrails, which experimental evidence suggests may alter weather patterns. Uses for aircraft Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model. Military A military aircraft is any aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: Combat aircraft are aircraft designed to destroy enemy equipment using its own armament. Combat aircraft divide broadly into fighters and bombers, with several in-between types, such as fighter-bombers and attack aircraft, including attack helicopters. Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. Non-combat roles include search and rescue, reconnaissance, observation, transport, training, and aerial refueling. These aircraft are often variants of civil aircraft. Most military aircraft are powered heavier-than-air types. Other types, such as gliders and balloons, have also been used as military aircraft; for example, balloons were used for observation during the American Civil War and World War I, and military gliders were used during World War II to land troops. Civil Civil aircraft divide into commercial and general types, however there are some overlaps. Commercial aircraft include types designed for scheduled and charter airline flights, carrying passengers, mail and other cargo.

Alfred Nobel Alfred Bernhard Nobel ( , ; 21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, inventor, businessman, and philanthropist. He is best known for having bequeathed his fortune to establish the Nobel Prize, though he also made several important contributions to science, holding 355 patents in his lifetime. Nobel's most famous invention was dynamite, a safer and easier means of harnessing the explosive power of nitroglycerin; it was patented in 1867 and was soon used worldwide for mining and infrastructure development. Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at age 24. He embarked on many business ventures with his family, most notably owning Bofors, an iron and steel producer that he developed into a major manufacturer of cannons and other armaments. After reading an erroneous obituary condemning him as a war profiteer, Nobel was inspired to bequeath his fortune to the Nobel Prize institution, which would annually recognize those who "conferred the greatest benefit to humankind". The synthetic element nobelium was named after him, and his name and legacy also survives in companies such as Dynamit Nobel and AkzoNobel, which descend from mergers with companies he founded. Nobel was elected a member of the Royal Swedish Academy of Sciences, which, pursuant to his will, would be responsible for choosing the Nobel laureates in physics and in chemistry. Personal life Early life and education Alfred Nobel was born in Stockholm, United Kingdoms of Sweden and Norway on 21 October 1833. He was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Karolina Andriette Nobel (née Ahlsell 1805–1889). The couple married in 1827 and had eight children. The family was impoverished and only Alfred and his three brothers survived beyond childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn, the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.Following various business failures, Nobel's father moved to Saint Petersburg, Russia and grew successful there as a manufacturer of machine tools and explosives. He invented the veneer lathe (which made possible the production of modern plywood) and started work on the torpedo. In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German and Russian. For 18 months, from 1841 to 1842, Nobel went to the only school he ever attended as a child, in Stockholm. Nobel gained proficiency in Swedish, French, Russian, English, German, and Italian. He also developed sufficient literary skill to write poetry in English. His Nemesis is a prose tragedy in four acts about Beatrice Cenci.

He also developed sufficient literary skill to write poetry in English. His Nemesis is a prose tragedy in four acts about Beatrice Cenci.

It was printed while he was dying, but the entire stock was destroyed immediately after his death except for three copies, being regarded as scandalous and blasphemous. It was published in Sweden in 2003 and has been translated into Slovenian and French. Religion Nobel was Lutheran and regularly attended the Church of Sweden Abroad during his Paris years, led by pastor Nathan Söderblom who received the Nobel Peace Prize in 1930. He became an agnostic in youth and was an atheist later in life, though still donated generously to the Church. Health and relationships Nobel travelled for much of his business life, maintaining companies in Europe and America while keeping a home in Paris from 1873 to 1891. He remained a solitary character, given to periods of depression. He remained unmarried, although his biographers note that he had at least three loves, the first in Russia with a girl named Alexandra who rejected his proposal. In 1876, Austro-Bohemian Countess Bertha Kinsky became his secretary, but she left him after a brief stay to marry her previous lover Baron Arthur Gundaccar von Suttner. Her contact with Nobel was brief, yet she corresponded with him until his death in 1896, and probably influenced his decision to include a peace prize in his will. She was awarded the 1905 Nobel Peace prize "for her sincere peace activities". Nobel's longest-lasting relationship was with Sofija Hess from Celje whom he met in 1876. The liaison lasted for 18 years. Residences In the years of 1865 to 1873, Alfred Nobel had his home in Krümmel, Hamburg, he afterward moved to a house in the Avenue Malakoff in Paris that same year.In 1894, when he acquired Bofors-Gullspång, the Björkborn Manor was included, he stayed at his manor house in Sweden during the summers. The manor house became his very last residence in Sweden and has after his death functioned as a museum. Alfred Nobel died on 10 December 1896, in Sanremo, Italy, at his very last residence, Villa Nobel, overlooking the Mediterranean Sea. Scientific career As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work. There he met Ascanio Sobrero, who had invented nitroglycerin three years before. Sobrero strongly opposed the use of nitroglycerin because it was unpredictable, exploding when subjected to variable heat or pressure. But Nobel became interested in finding a way to control and use nitroglycerin as a commercially usable explosive; it had much more power than gunpowder. In 1851 at age 18, he went to the United States for one year to study, working for a short period under Swedish-American inventor John Ericsson, who designed the American Civil War ironclad, USS Monitor.

Nobel filed his first patent, an English patent for a gas meter, in 1857, while his first Swedish patent, which he received in 1863, was on "ways to prepare gunpowder".The family factory produced armaments for the Crimean War (1853–1856), but had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerin. Nobel invented a detonator in 1863, and in 1865 designed the blasting cap. On 3 September 1864, a shed used for preparation of nitroglycerin exploded at the factory in Heleneborg, Stockholm, Sweden, killing five people, including Nobel's younger brother Emil. Fazed by the accident, Nobel founded the company Nitroglycerin Aktiebolaget AB in Vinterviken so that he could continue to work in a more isolated area. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875, Nobel invented gelignite, more stable and powerful than dynamite, and in 1887, patented ballistite, a predecessor of cordite. Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893. Nobel's brothers Ludvig and Robert founded the oil company Branobel and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. During his life, Nobel was issued 355 patents internationally, and by his death, his business had established more than 90 armaments factories, despite his apparently pacifist character. Inventions Nobel found that when nitroglycerin was incorporated in an absorbent inert substance like kieselguhr (diatomaceous earth) it became safer and more convenient to handle, and this mixture he patented in 1867 as "dynamite". Nobel demonstrated his explosive for the first time that year, at a quarry in Redhill, Surrey, England. In order to help reestablish his name and improve the image of his business from the earlier controversies associated with dangerous explosives, Nobel had also considered naming the highly powerful substance "Nobel's Safety Powder", but settled with Dynamite instead, referring to the Greek word for "power" (). Nobel later combined nitroglycerin with various nitrocellulose compounds, similar to collodion, but settled on a more efficient recipe combining another nitrate explosive, and obtained a transparent, jelly-like substance, which was a more powerful explosive than dynamite. Gelignite, or blasting gelatine, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances.

Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds. It was adopted as the standard technology for mining in the "Age of Engineering", bringing Nobel a great amount of financial success, though at a cost to his health. An offshoot of this research resulted in Nobel's invention of ballistite, the precursor of many modern smokeless powder explosives and still used as a rocket propellant. Nobel Prize In 1888, the death of his brother Ludvig caused several newspapers to publish obituaries of Alfred in error. One French newspaper condemned him for his invention of military explosives—not, as is commonly quoted, dynamite, which was mainly used for civilian applications—and is said to have brought about his decision to leave a better legacy after his death. The obituary stated, ("The merchant of death is dead"), and went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday." Nobel read the obituary and was appalled at the idea that he would be remembered in this way. His decision to posthumously donate the majority of his wealth to found the Nobel Prize has been credited at least in part to him wanting to leave behind a better legacy. On 27 November 1895, at the Swedish-Norwegian Club in Paris, Nobel signed his last will and testament and set aside the bulk of his estate to establish the Nobel Prizes, to be awarded annually without distinction of nationality. After taxes and bequests to individuals, Nobel's will allocated 94% of his total assets, 31,225,000 Swedish kronor, to establish the five Nobel Prizes. This converted to £1,687,837 (GBP) at the time. In 2012, the capital was worth around SEK 3.1 billion (US$472 million, EUR 337 million), which is almost twice the amount of the initial capital, taking inflation into account. The first three of these prizes are awarded for eminence in physical science, in chemistry and in medical science or physiology; the fourth is for literary work "in an ideal direction" and the fifth prize is to be given to the person or society that renders the greatest service to the cause of international fraternity, in the suppression or reduction of standing armies, or in the establishment or furtherance of peace congresses. The formulation for the literary prize being given for a work "in an ideal direction" ( in Swedish), is cryptic and has caused much confusion. For many years, the Swedish Academy interpreted "ideal" as "idealistic" () and used it as a reason not to give the prize to important but less romantic authors, such as Henrik Ibsen and Leo Tolstoy. This interpretation has since been revised, and the prize has been awarded to, for example, Dario Fo and José Saramago, who do not belong to the camp of literary idealism.

Nobel read the obituary and was appalled at the idea that he would be remembered in this way. His decision to posthumously donate the majority of his wealth to found the Nobel Prize has been credited at least in part to him wanting to leave behind a better legacy. On 27 November 1895, at the Swedish-Norwegian Club in Paris, Nobel signed his last will and testament and set aside the bulk of his estate to establish the Nobel Prizes, to be awarded annually without distinction of nationality. After taxes and bequests to individuals, Nobel's will allocated 94% of his total assets, 31,225,000 Swedish kronor, to establish the five Nobel Prizes. This converted to £1,687,837 (GBP) at the time. In 2012, the capital was worth around SEK 3.1 billion (US$472 million, EUR 337 million), which is almost twice the amount of the initial capital, taking inflation into account. The first three of these prizes are awarded for eminence in physical science, in chemistry and in medical science or physiology; the fourth is for literary work "in an ideal direction" and the fifth prize is to be given to the person or society that renders the greatest service to the cause of international fraternity, in the suppression or reduction of standing armies, or in the establishment or furtherance of peace congresses. The formulation for the literary prize being given for a work "in an ideal direction" ( in Swedish), is cryptic and has caused much confusion. For many years, the Swedish Academy interpreted "ideal" as "idealistic" () and used it as a reason not to give the prize to important but less romantic authors, such as Henrik Ibsen and Leo Tolstoy. This interpretation has since been revised, and the prize has been awarded to, for example, Dario Fo and José Saramago, who do not belong to the camp of literary idealism.

Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds. It was adopted as the standard technology for mining in the "Age of Engineering", bringing Nobel a great amount of financial success, though at a cost to his health. An offshoot of this research resulted in Nobel's invention of ballistite, the precursor of many modern smokeless powder explosives and still used as a rocket propellant. Nobel Prize In 1888, the death of his brother Ludvig caused several newspapers to publish obituaries of Alfred in error. One French newspaper condemned him for his invention of military explosives—not, as is commonly quoted, dynamite, which was mainly used for civilian applications—and is said to have brought about his decision to leave a better legacy after his death. The obituary stated, ("The merchant of death is dead"), and went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday."

There was room for interpretation by the bodies he had named for deciding on the physical sciences and chemistry prizes, given that he had not consulted them before making the will. In his one-page testament, he stipulated that the money go to discoveries or inventions in the physical sciences and to discoveries or improvements in chemistry. He had opened the door to technological awards, but had not left instructions on how to deal with the distinction between science and technology. Since the deciding bodies he had chosen were more concerned with the former, the prizes went to scientists more often than engineers, technicians or other inventors. Sweden's central bank Sveriges Riksbank celebrated its 300th anniversary in 1968 by donating a large sum of money to the Nobel Foundation to be used to set up a sixth prize in the field of economics in honour of Alfred Nobel. In 2001, Alfred Nobel's great-great-nephew, Peter Nobel (born 1931), asked the Bank of Sweden to differentiate its award to economists given "in Alfred Nobel's memory" from the five other awards. This request added to the controversy over whether the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel is actually a legitimate "Nobel Prize". Death Nobel was accused of high treason against France for selling Ballistite to Italy, so he moved from Paris to Sanremo, Italy in 1891. On 10 December 1896, he suffered a stroke and died. He had left most of his wealth in trust, unbeknownst to his family, in order to fund the Nobel Prize awards. He is buried in Norra begravningsplatsen in Stockholm. Monuments and legacy The Monument to Alfred Nobel (, ) in Saint Petersburg is located along the Bolshaya Nevka River on Petrogradskaya Embankment. It was dedicated in 1991 to mark the 90th anniversary of the first Nobel Prize presentation. Diplomat Thomas Bertelman and Professor Arkady Melua were initiators of the creation of the monument (1989). Professor A. Melua has provided funds for the establishment of the monument (J.S.Co. "Humanistica", 1990–1991). The abstract metal sculpture was designed by local artists Sergey Alipov and Pavel Shevchenko, and appears to be an explosion or branches of a tree. Petrogradskaya Embankment is the street where the Nobel's family lived until 1859. Criticism of Nobel focuses on his leading role in weapons manufacturing and sales, and some question his motives in creating his prizes, suggesting they are intended to improve his reputation.

Alexander Graham Bell Alexander Graham Bell (, born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born inventor, scientist, and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf; profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Although Bell was not one of the 33 founders of the National Geographic Society, he had a strong influence on the magazine while serving as the second president from January 7, 1898, until 1903. Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity. Early life Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845–1870) and Edward Charles Bell (1848–1867), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace Bell (née Symonds). Born as just "Alexander Bell", at age 10, he made a plea to his father to have a middle name like his two brothers. For his 11th birthday, his father acquiesced and allowed him to adopt the name "Graham", chosen out of respect for Alexander Graham, a Canadian being treated by his father who had become a family friend. To close relatives and friends he remained "Aleck". First invention As a child, young Bell displayed a curiosity about his world; he gathered botanical specimens and ran experiments at an early age. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. At the age of 12, Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation at the mill and used steadily for a number of years. In return, Ben's father John Herdman gave both boys the run of a small workshop in which to "invent". From his early years, Bell showed a sensitive nature and a talent for art, poetry, and music that was encouraged by his mother. With no formal training, he mastered the piano and became the family's pianist. Despite being normally quiet and introspective, he revelled in mimicry and "voice tricks" akin to ventriloquism that continually entertained family guests during their occasional visits.

Despite being normally quiet and introspective, he revelled in mimicry and "voice tricks" akin to ventriloquism that continually entertained family guests during their occasional visits.

Bell was also deeply affected by his mother's gradual deafness (she began to lose her hearing when he was 12), and learned a manual finger language so he could sit at her side and tap out silently the conversations swirling around the family parlour. He also developed a technique of speaking in clear, modulated tones directly into his mother's forehead wherein she would hear him with reasonable clarity. Bell's preoccupation with his mother's deafness led him to study acoustics. His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. His father published a variety of works on the subject, several of which are still well known, especially his The Standard Elocutionist (1860), which appeared in Edinburgh in 1868. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. In this treatise, his father explains his methods of how to instruct deaf-mutes (as they were then known) to articulate words and read other people's lip movements to decipher meaning. Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. Bell became so proficient that he became a part of his father's public demonstrations and astounded audiences with his abilities. He could decipher Visible Speech representing virtually every language, including Latin, Scottish Gaelic, and even Sanskrit, accurately reciting written tracts without any prior knowledge of their pronunciation. Education As a young child, Bell, like his brothers, received his early schooling at home from his father. At an early age, he was enrolled at the Royal High School, Edinburgh, Scotland, which he left at the age of 15, having completed only the first four forms. His school record was undistinguished, marked by absenteeism and lacklustre grades. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. Upon leaving school, Bell travelled to London to live with his grandfather, Alexander Bell, on Harrington Square. During the year he spent with his grandfather, a love of learning was born, with long hours spent in serious discussion and study. The elder Bell took great efforts to have his young pupil learn to speak clearly and with conviction, the attributes that his pupil would need to become a teacher himself. At the age of 16, Bell secured a position as a "pupil-teacher" of elocution and music, in Weston House Academy at Elgin, Moray, Scotland. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and £10 per session. The following year, he attended the University of Edinburgh, joining his older brother Melville who had enrolled there the previous year.

In 1868, not long before he departed for Canada with his family, Bell completed his matriculation exams and was accepted for admission to University College London. First experiments with sound His father encouraged Bell's interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. The rudimentary "mechanical man" simulated a human voice. Bell was fascinated by the machine and after he obtained a copy of von Kempelen's book, published in German, and had laboriously translated it, he and his older brother Melville built their own automaton head. Their father, highly interested in their project, offered to pay for any supplies and spurred the boys on with the enticement of a "big prize" if they were successful. While his brother constructed the throat and larynx, Bell tackled the more difficult task of recreating a realistic skull. His efforts resulted in a remarkably lifelike head that could "speak", albeit only a few words. The boys would carefully adjust the "lips" and when a bellows forced air through the windpipe, a very recognizable "Mama" ensued, to the delight of neighbours who came to see the Bell invention. Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, "Trouve". After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". With little convincing, visitors believed his dog could articulate "How are you, grandmama?" Indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". These initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance. At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father. Ellis immediately wrote back indicating that the experiments were similar to existing work in Germany, and also lent Bell a copy of Hermann von Helmholtz's work, The Sensations of Tone as a Physiological Basis for the Theory of Music. Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork "contraption", Bell pored over the German scientist's book. Working from his own erroneous mistranslation of a French edition, Bell fortuitously then made a deduction that would be the underpinning of all his future work on transmitting sound, reporting: "Without knowing much about the subject, it seemed to me that if vowel sounds could be produced by electrical means, so could consonants, so could articulate speech." He also later remarked: "I thought that Helmholtz had done it ... and that my failure was due only to my ignorance of electricity. It was a valuable blunder ...

With little convincing, visitors believed his dog could articulate "How are you, grandmama?" Indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". These initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance. At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father. Ellis immediately wrote back indicating that the experiments were similar to existing work in Germany, and also lent Bell a copy of Hermann von Helmholtz's work, The Sensations of Tone as a Physiological Basis for the Theory of Music. Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork "contraption", Bell pored over the German scientist's book. Working from his own erroneous mistranslation of a French edition, Bell fortuitously then made a deduction that would be the underpinning of all his future work on transmitting sound, reporting: "Without knowing much about the subject, it seemed to me that if vowel sounds could be produced by electrical means, so could consonants, so could articulate speech." He also later remarked: "I thought that Helmholtz had done it ... and that my failure was due only to my ignorance of electricity. It was a valuable blunder ...

In 1868, not long before he departed for Canada with his family, Bell completed his matriculation exams and was accepted for admission to University College London. First experiments with sound His father encouraged Bell's interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. The rudimentary "mechanical man" simulated a human voice. Bell was fascinated by the machine and after he obtained a copy of von Kempelen's book, published in German, and had laboriously translated it, he and his older brother Melville built their own automaton head. Their father, highly interested in their project, offered to pay for any supplies and spurred the boys on with the enticement of a "big prize" if they were successful. While his brother constructed the throat and larynx, Bell tackled the more difficult task of recreating a realistic skull. His efforts resulted in a remarkably lifelike head that could "speak", albeit only a few words. The boys would carefully adjust the "lips" and when a bellows forced air through the windpipe, a very recognizable "Mama" ensued, to the delight of neighbours who came to see the Bell invention.

If I had been able to read German in those days, I might never have commenced my experiments!" Family tragedy In 1865, when the Bell family moved to London, Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment. Bell concentrated on experimenting with electricity to convey sound and later installed a telegraph wire from his room in Somerset College to that of a friend. Throughout late 1867, his health faltered mainly through exhaustion. His younger brother, Edward "Ted," was similarly bed-ridden, suffering from tuberculosis. While Bell recovered (by then referring to himself in correspondence as "A. G. Bell") and served the next year as an instructor at Somerset College, Bath, England, his brother's condition deteriorated. Edward would never recover. Upon his brother's death, Bell returned home in 1867. His older brother Melville had married and moved out. With aspirations to obtain a degree at University College London, Bell considered his next years as preparation for the degree examinations, devoting his spare time at his family's residence to studying. Helping his father in Visible Speech demonstrations and lectures brought Bell to Susanna E. Hull's private school for the deaf in South Kensington, London. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. While his older brother seemed to achieve success on many fronts including opening his own elocution school, applying for a patent on an invention, and starting a family, Bell continued as a teacher. However, in May 1870, Melville died from complications due to tuberculosis, causing a family crisis. His father had also suffered a debilitating illness earlier in life and had been restored to health by a convalescence in Newfoundland. Bell's parents embarked upon a long-planned move when they realized that their remaining son was also sickly. Acting decisively, Alexander Melville Bell asked Bell to arrange for the sale of all the family property, conclude all of his brother's affairs (Bell took over his last student, curing a pronounced lisp), and join his father and mother in setting out for the "New World". Reluctantly, Bell also had to conclude a relationship with Marie Eccleston, who, as he had surmised, was not prepared to leave England with him. Canada In 1870, 23-year-old Bell travelled with his parents and his brother's widow, Caroline Margaret Ottaway, to Paris, Ontario, to stay with Thomas Henderson, a Baptist minister and family friend. The Bell family soon purchased a farm of at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario. The property consisted of an orchard, large farmhouse, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River. At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his "dreaming place", a large hollow nestled in trees at the back of the property above the river.

Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved. He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols. For his work, Bell was awarded the title of Honorary Chief and participated in a ceremony where he donned a Mohawk headdress and danced traditional dances. After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. He also modified a melodeon (a type of pump organ) so that it could transmit its music electrically over a distance. Once the family was settled in, both Bell and his father made plans to establish a teaching practice and in 1871, he accompanied his father to Montreal, where Melville was offered a position to teach his System of Visible Speech. Work with the deaf Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (which continues today as the public Horace Mann School for the Deaf), in Boston, Massachusetts, United States, to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favour of his son. Travelling to Boston in April 1871, Bell proved successful in training the school's instructors. He was subsequently asked to repeat the programme at the American Asylum for Deaf-mutes in Hartford, Connecticut, and the Clarke School for the Deaf in Northampton, Massachusetts. Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph". The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed. Unsure of his future, he first contemplated returning to London to complete his studies, but decided to return to Boston as a teacher. His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. While he was working as a private tutor, one of his pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. She was later to say that Bell dedicated his life to the penetration of that "inhuman silence which separates and estranges". In 1893, Keller performed the sod-breaking ceremony for the construction of Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf". Throughout his lifetime, Bell sought to integrate the deaf and hard of hearing with the hearing world.

Throughout his lifetime, Bell sought to integrate the deaf and hard of hearing with the hearing world.

To achieve complete assimilation in society, Bell encouraged speech therapy and lip reading as well as sign language. He outlined this in a 1898 paper detailing his belief that with resources and effort, the deaf could be taught to read lips and speak (known as oralism) thus enabling their integration within the wider society from which many were often being excluded. Owing to his efforts to balance oralism with the teaching of sign language, Bell is often viewed negatively by those embracing Deaf culture. Ironically, Bell's last words to his deaf wife, Mabell, were signed. Continuing experimentation In 1872, Bell became professor of Vocal Physiology and Elocution at the Boston University School of Oratory. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. He continued his research in sound and endeavored to find a way to transmit musical notes and articulate speech, but although absorbed by his experiments, he found it difficult to devote enough time to experimentation. While days and evenings were occupied by his teaching and private classes, Bell began to stay awake late into the night, running experiment after experiment in rented facilities at his boarding house. Keeping "night owl" hours, he worried that his work would be discovered and took great pains to lock up his notebooks and laboratory equipment. Bell had a specially made table where he could place his notes and equipment inside a locking cover. Worse still, his health deteriorated as he suffered severe headaches. Returning to Boston in fall 1873, Bell made a far-reaching decision to concentrate on his experiments in sound. Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old "Georgie" Sanders, deaf from birth, and 15-year-old Mabel Hubbard. Each pupil would play an important role in the next developments. George's father, Thomas Sanders, a wealthy businessman, offered Bell a place to stay in nearby Salem with Georgie's grandmother, complete with a room to "experiment". Although the offer was made by George's mother and followed the year-long arrangement in 1872 where her son and his nurse had moved to quarters next to Bell's boarding house, it was clear that Mr. Sanders was backing the proposal. The arrangement was for teacher and student to continue their work together, with free room and board thrown in. Mabel was a bright, attractive girl who was ten years Bell's junior but became the object of his affection. Having lost her hearing after a near-fatal bout of scarlet fever close to her fifth birthday, she had learned to read lips but her father, Gardiner Greene Hubbard, Bell's benefactor and personal friend, wanted her to work directly with her teacher.

The telephone By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas. In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok. In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech. The race to the patent office In 1875, Bell developed an acoustic telegraph and drew up a patent application for it.

Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok. In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech. The race to the patent office In 1875, Bell developed an acoustic telegraph and drew up a patent application for it.

Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain (Britain would issue patents only for discoveries not previously patented elsewhere). Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. On February 14, 1876, Gray filed a caveat with the U.S. Patent Office for a telephone design that used a water transmitter. That same morning, Bell's lawyer filed Bell's application with the patent office. There is considerable debate about who arrived first and Gray later challenged the primacy of Bell's patent. Bell was in Boston on February 14 and did not arrive in Washington until February 26. Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat. On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray's design. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the sentence "Mr. Watson—Come here—I want to see you" into the liquid transmitter, Watson, listening at the receiving end in an adjoining room, heard the words clearly. Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use. The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in his previous application in which he described a cup of mercury, not water. He had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876.

Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone. The patent examiner, Zenas Fisk Wilber, later stated in an affidavit that he was an alcoholic who was much in debt to Bell's lawyer, Marcellus Bailey, with whom he had served in the Civil War. He claimed he showed Gray's patent caveat to Bailey. Wilber also claimed (after Bell arrived in Washington D.C. from Boston) that he showed Gray's caveat to Bell and that Bell paid him $100 (). Bell claimed they discussed the patent only in general terms, although in a letter to Gray, Bell admitted that he learned some of the technical details. Bell denied in an affidavit that he ever gave Wilber any money. Later developments On March 10, 1876, Bell used "the instrument" in Boston to call Thomas Watson who was in another room but out of earshot. He said, "Mr. Watson, come here – I want to see you" and Watson soon appeared at his side. Continuing his experiments in Brantford, Bell brought home a working model of his telephone. On August 3, 1876, from the telegraph office in Brantford, Ontario, Bell sent a tentative telegram to the village of Mount Pleasant distant, indicating that he was ready. He made a telephone call via telegraph wires and faint voices were heard replying. The following night, he amazed guests as well as his family with a call between the Bell Homestead and the office of the Dominion Telegraph Company in Brantford along an improvised wire strung up along telegraph lines and fences, and laid through a tunnel. This time, guests at the household distinctly heard people in Brantford reading and singing. The third test on August 10, 1876, was made via the telegraph line between Brantford and Paris, Ontario, distant. This test was said by many sources to be the "world's first long-distance call". The final test certainly proved that the telephone could work over long distances, at least as a one-way call. The first two-way (reciprocal) conversation over a line occurred between Cambridge and Boston (roughly 2.5 miles) on October 9, 1876. During that conversation, Bell was on Kilby Street in Boston and Watson was at the offices of the Walworth Manufacturing Company. Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000. The president of Western Union balked, countering that the telephone was nothing but a toy. Two years later, he told colleagues that if he could get the patent for $25 million he would consider it a bargain. By then, the Bell company no longer wanted to sell the patent. Bell's investors would become millionaires while he fared well from residuals and at one point had assets of nearly one million dollars. Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public.

Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public.

A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. Influential visitors to the exhibition included Emperor Pedro II of Brazil. One of the judges at the Exhibition, Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, described the telephone as "the greatest by far of all the marvels of the electric telegraph". On January 14, 1878, at Osborne House, on the Isle of Wight, Bell demonstrated the device to Queen Victoria, placing calls to Cowes, Southampton and London. These were the first publicly witnessed long-distance telephone calls in the UK. The queen considered the process to be "quite extraordinary" although the sound was "rather faint". She later asked to buy the equipment that was used, but Bell offered to make "a set of telephones" specifically for her. The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. Bell Company engineers made numerous other improvements to the telephone, which emerged as one of the most successful products ever. In 1879, the Bell company acquired Edison's patents for the carbon microphone from Western Union. This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. Emperor Pedro II of Brazil was the first person to buy stock in Bell's company, the Bell Telephone Company. One of the first telephones in a private residence was installed in his palace in Petrópolis, his summer retreat from Rio de Janeiro. In January 1915, Bell made the first ceremonial transcontinental telephone call. Calling from the AT&T head office at 15 Dey Street in New York City, Bell was heard by Thomas Watson at 333 Grant Avenue in San Francisco. The New York Times reported: Competitors As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court, but none was successful in establishing priority over the original Bell patent and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. Bell's laboratory notes and family letters were the key to establishing a long lineage to his experiments. The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims. On January 13, 1887, the U.S. Government moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation. After a series of decisions and reversals, the Bell company won a decision in the Supreme Court, though a couple of the original claims from the lower court cases were left undecided.

By the time that the trial wound its way through nine years of legal battles, the U.S. prosecuting attorney had died and the two Bell patents (No. 174,465 dated March 7, 1876, and No. 186,787 dated January 30, 1877) were no longer in effect, although the presiding judges agreed to continue the proceedings due to the case's importance as a precedent. With a change in administration and charges of conflict of interest (on both sides) arising from the original trial, the US Attorney General dropped the lawsuit on November 30, 1897, leaving several issues undecided on the merits. During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hope of establishing his invention's priority. Meucci's testimony in this case was disputed due to a lack of material evidence for his inventions, as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002, stated that Meucci's "work in the invention of the telephone should be acknowledged". This did not put an end to the still-contentious issue. Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions. The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell delayed the German patent application, the electrical firm of Siemens & Halske set up a rival manufacturer of Bell telephones under their own patent. The Siemens company produced near-identical copies of the Bell telephone without having to pay royalties. The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. Family life On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (1857–1923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday".

In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hope of establishing his invention's priority. Meucci's testimony in this case was disputed due to a lack of material evidence for his inventions, as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002, stated that Meucci's "work in the invention of the telephone should be acknowledged". This did not put an end to the still-contentious issue. Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions. The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell delayed the German patent application, the electrical firm of Siemens & Halske set up a rival manufacturer of Bell telephones under their own patent. The Siemens company produced near-identical copies of the Bell telephone without having to pay royalties. The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. Family life On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (1857–1923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday".

The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancée was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children: Elsie May Bell (1878–1964) who married Gilbert Hovey Grosvenor of National Geographic fame. Marian Hubbard Bell (1880–1962) who was referred to as "Daisy". Married David Fairchild. Two sons who died in infancy (Edward in 1881 and Robert in 1883). The Bell family home was in Cambridge, Massachusetts, until 1880 when Bell's father-in-law bought a house in Washington, D.C.; in 1882 he bought a home in the same city for Bell's family, so they could be with him while he attended to the numerous court cases involving patent disputes. Bell was a British subject throughout his early life in Scotland and later in Canada until 1882 when he became a naturalized citizen of the United States. In 1915, he characterized his status as: "I am not one of those hyphenated Americans who claim allegiance to two countries." Despite this declaration, Bell has been proudly claimed as a "native son" by all three countries he resided in: the United States, Canada, and the United Kingdom. By 1885, a new summer retreat was contemplated. That summer, the Bells had a vacation on Cape Breton Island in Nova Scotia, spending time at the small village of Baddeck. Returning in 1886, Bell started building an estate on a point across from Baddeck, overlooking Bras d'Or Lake. By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory, were begun that the Bells would name Beinn Bhreagh (Gaelic: Beautiful Mountain) after Bell's ancestral Scottish highlands. Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family. He was an enthusiastic boater, and Bell and his family sailed or rowed a long series of vessels on Bras d'Or Lake, ordering additional vessels from the H.W. Embree and Sons boatyard in Port Hawkesbury, Nova Scotia. In his final, and some of his most productive years, Bell split his residency between Washington, D.C., where he and his family initially resided for most of the year, and Beinn Bhreagh, where they spent increasing amounts of time. Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened.

Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own". The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Mabel and Bell mobilized the community to help victims in Halifax. Later inventions Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. According to one of his biographers, Charlotte Gray, Bell's work ranged "unfettered across the scientific landscape" and he often went to bed voraciously reading the Encyclopædia Britannica, scouring it for new areas of interest. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels. Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive, and other magnetic media. Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses. Photophone Bell and his assistant Charles Sumner Tainter jointly invented a wireless telephone, named a photophone, which allowed for the transmission of both sounds and normal human conversations on a beam of light. Both men later became full associates in the Volta Laboratory Association. On June 21, 1880, Bell's assistant transmitted a wireless voice telephone message a considerable distance, from the roof of the Franklin School in Washington, D.C., to Bell at the window of his laboratory, some away, 19 years before the first voice radio transmissions. Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone".

The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use. Metal detector Bell is also credited with developing one of the early versions of a metal detector through the use of an induction balance, after the shooting of U.S. President James A. Garfield in 1881. According to some accounts, the metal detector worked flawlessly in tests but did not find Guiteau's bullet, partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. Garfield's surgeons, led by self-appointed chief physician Doctor Willard Bliss, were skeptical of the device, and ignored Bell's requests to move the President to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus. Bell's own detailed account, presented to the American Association for the Advancement of Science in 1882, differs in several particulars from most of the many and varied versions now in circulation, by concluding that extraneous metal was not to blame for failure to locate the bullet. Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "proceeded to the Executive Mansion the next morning ... to ascertain from the surgeons whether they were perfectly sure that all metal had been removed from the neighborhood of the bed. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires. Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." In a footnote, Bell adds, "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus." Hydrofoils The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft. During his world tour of 1910–11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore.

During his world tour of 1910–11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore.

Baldwin described it as being as smooth as flying. On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag (Scottish Gaelic for little devil), the first self-propelled Bell-Baldwin hydrofoil. The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. A top speed of was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia, to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boat-building enabled him to make useful design changes to the HD-4. After the First World War, work began again on the HD-4. Bell's report to the U.S. Navy permitted him to obtain two engines in July 1919. On September 9, 1919, the HD-4 set a world marine speed record of , a record which stood for ten years. Aeronautics In 1891, Bell had begun experiments to develop motor-powered heavier-than-air aircraft. The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of 60. In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk. The tetrahedral wings were named Cygnet I, II, and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 1907 to 1912. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site. Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. The AEA was headed by Bell and the founding members were four young men: American Glenn H. Curtiss, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York; and J. A. D. McCurdy–Baldwin and McCurdy being new engineering graduates from the University of Toronto. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders.

On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag (Scottish Gaelic for little devil), the first self-propelled Bell-Baldwin hydrofoil. The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. A top speed of was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia, to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boat-building enabled him to make useful design changes to the HD-4. After the First World War, work began again on the HD-4. Bell's report to the U.S. Navy permitted him to obtain two engines in July 1919. On September 9, 1919, the HD-4 set a world marine speed record of , a record which stood for ten years. Aeronautics In 1891, Bell had begun experiments to develop motor-powered heavier-than-air aircraft. The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of 60. In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk. The tetrahedral wings were named Cygnet I, II, and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 1907 to 1912. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site. Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. The AEA was headed by Bell and the founding members were four young men: American Glenn H. Curtiss, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York; and J. A. D. McCurdy–Baldwin and McCurdy being new engineering graduates from the University of Toronto. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders.

Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America. The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908. Their final aircraft design, the Silver Dart, embodied all of the advancements found in the earlier machines. On February 23, 1909, Bell was present as the Silver Dart flown by J. A. D. McCurdy from the frozen ice of Bras d'Or made the first aircraft flight in Canada. Bell had worried that the flight was too dangerous and had arranged for a doctor to be on hand. With the successful flight, the AEA disbanded and the Silver Dart would revert to Baldwin and McCurdy, who began the Canadian Aerodrome Company and would later demonstrate the aircraft to the Canadian Army. Heredity and genetics Bell, along with many members of the scientific community at the time, took an interest in the popular science of heredity which grew out of the publication of Charles Darwin's book On the Origin of Species in 1859. On his estate in Nova Scotia, Bell conducted meticulously recorded breeding experiments with rams and ewes. Over the course of more than 30 years, Bell sought to produce a breed of sheep with multiple nipples that would bear twins. He specifically wanted to see if selective breeding could produce sheep with four functional nipples with enough milk for twin lambs. This interest in animal breeding caught the attention of scientists focused on the study of heredity and genetics in humans. In November 1883, Bell presented a paper at a meeting of the National Academy of Sciences titled "Upon the Formation of a Deaf Variety of the Human Race". The paper is a compilation of data on the hereditary aspects of deafness. Bell's research indicated that a hereditary tendency toward deafness, as indicated by the possession of deaf relatives, was an important element in determining the production of deaf offspring. He noted that the proportion of deaf children born to deaf parents was many times greater than the proportion of deaf children born to the general population.

In the paper, Bell delved into social commentary and discussed hypothetical public policies to bring an end to deafness. He also criticized educational practices that segregated deaf children rather than integrated them fulling into mainstream classrooms. The paper did not propose sterilization of deaf people or prohibition on intermarriage, noting that “We cannot dictate to men and women whom they should marry and natural selection no longer influences mankind to any great extent.” A review of Bell's "Memoir upon the Formation of a Deaf Variety of the Human Race" appearing in an 1885 issue of the "American Annals of the Deaf and Dumb" states that "Dr. Bell does not advocate legislative interference with the marriages of the deaf for several reasons one of which is that the results of such marriages have not yet been sufficiently investigated." The article goes on to say that "the editorial remarks based thereon did injustice to the author." The paper's author concludes by saying “A wiser way to prevent the extension of hereditary deafness, it seems to us, would be to continue the investigations which Dr. Bell has so admirable begun until the laws of the transmission of the tendency to deafness are fully understood, and then by explaining those laws to the pupils of our schools to lead them to choose their partners in marriage in such a way that deaf-mute offspring will not be the result." Historians have noted that Bell explicitly opposed laws regulating marriage, and never mentioned sterilization in any of his writings. Even after Bell agreed to engage with scientists conducting eugenic research, he consistently refused to support public policy that limited the rights or privileges of the deaf. Bell's interest and research on heredity attracted the interest of Charles Davenport, a Harvard professor and head of the Cold Spring Harbor Laboratory. In 1906, Davenport, who was also the founder of the American Breeder's Association, approached Bell about joining a new committee on eugenics chaired by David Starr Jordan. In 1910, Davenport opened the Eugenics Records office at Cold Spring Harbor. To give the organization scientific credibility, Davenport set up a Board of Scientific Directors naming Bell as chairman. Other members of the board included Luther Burbank, Roswell H. Johnson, Vernon L. Kellogg, and William E. Castle. In 1921, a Second International Congress of Eugenics was held in New York at the Museum of Natural History and chaired by Davenport. Although Bell did not present any research or speak as part of the proceedings, he was named as honorary president as a means to attract other scientists to attend the event. A summary of the event notes that Bell was a "pioneering investigator in the field of human heredity". Death Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75. Bell had also been afflicted with pernicious anemia.

His last view of the land he had inhabited was by moonlight on his mountain estate at 2:00 a.m. While tending to him after his long illness, Mabel, his wife, whispered, "Don't leave me." By way of reply, Bell signed "no...", lost consciousness, and died shortly after. On learning of Bell's death, the Canadian Prime Minister, Mackenzie King, cabled Mrs. Bell, saying: Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments. To help celebrate his life, his wife asked guests not to wear black (the traditional funeral color) while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson's "Requiem": Upon the conclusion of Bell's funeral, for one minute at 6:25 p.m. Eastern Time, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance". Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake. He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren. Legacy and honors Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew. Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. During his life, he also received dozens of major awards, medals, and other tributes. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford, Ontario, in 1917. A large number of Bell's writings, personal correspondence, notebooks, papers, and other documents reside in both the United States Library of Congress Manuscript Division (as the Alexander Graham Bell Family Papers), and at the Alexander Graham Bell Institute, Cape Breton University, Nova Scotia; major portions of which are available for online viewing. A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada. Among the major sites are: The Alexander Graham Bell National Historic Site, maintained by Parks Canada, which incorporates the Alexander Graham Bell Museum, in Baddeck, Nova Scotia, close to the Bell estate Beinn Bhreagh The Bell Homestead National Historic Site, includes the Bell family home, "Melville House", and farm overlooking Brantford, Ontario and the Grand River. It was their first home in North America; Canada's first telephone company building, the "Henderson Home" of the late 1870s, a predecessor of the Bell Telephone Company of Canada (officially chartered in 1880). In 1969, the building was carefully moved to the historic Bell Homestead National Historic Site in Brantford, Ontario, and was refurbished to become a telephone museum.

The Bell Homestead, the Henderson Home telephone museum, and the National Historic Site's reception centre are all maintained by the Bell Homestead Society; The Alexander Graham Bell Memorial Park, which features a broad neoclassical monument built in 1917 by public subscription. The monument depicts mankind's ability to span the globe through telecommunications; The Alexander Graham Bell Museum (opened in 1956), part of the Alexander Graham Bell National Historic Site which was completed in 1978 in Baddeck, Nova Scotia. Many of the museum's artifacts were donated by Bell's daughters; In 1880, Bell received the Volta Prize with a purse of 50,000 French francs (approximately US$ in today's dollars) for the invention of the telephone from the French government. Among the luminaries who judged were Victor Hugo and Alexandre Dumas, fils. The Volta Prize was conceived by Napoleon III in 1852, and named in honor of Alessandro Volta, with Bell becoming the second recipient of the grand prize in its history. Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness. In partnership with Gardiner Greene Hubbard, Bell helped establish the publication Science during the early 1880s. In 1898, Bell was elected as the second president of the National Geographic Society, serving until 1903, and was primarily responsible for the extensive use of illustrations, including photography, in the magazine. He also served for many years as a Regent of the Smithsonian Institution (1898–1922). The French government conferred on him the decoration of the Légion d'honneur (Legion of Honor); the Royal Society of Arts in London awarded him the Albert Medal in 1902; the University of Würzburg, Bavaria, granted him a PhD, and he was awarded the Franklin Institute's Elliott Cresson Medal in 1912. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone".

The Volta Prize was conceived by Napoleon III in 1852, and named in honor of Alessandro Volta, with Bell becoming the second recipient of the grand prize in its history. Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness. In partnership with Gardiner Greene Hubbard, Bell helped establish the publication Science during the early 1880s. In 1898, Bell was elected as the second president of the National Geographic Society, serving until 1903, and was primarily responsible for the extensive use of illustrations, including photography, in the magazine. He also served for many years as a Regent of the Smithsonian Institution (1898–1922). The French government conferred on him the decoration of the Légion d'honneur (Legion of Honor); the Royal Society of Arts in London awarded him the Albert Medal in 1902; the University of Würzburg, Bavaria, granted him a PhD, and he was awarded the Franklin Institute's Elliott Cresson Medal in 1912. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone".

The bel (B) and the smaller decibel (dB) are units of measurement of sound pressure level (SPL) invented by Bell Labs and named after him. Since 1976, the IEEE's Alexander Graham Bell Medal has been awarded to honor outstanding contributions in the field of telecommunications. In 1936, the US Patent Office declared Bell first on its list of the country's greatest inventors, leading to the US Post Office issuing a commemorative stamp honoring Bell in 1940 as part of its 'Famous Americans Series'. The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf. The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series. The 150th anniversary of Bell's birth in 1997 was marked by a special issue of commemorative £1 banknotes from the Royal Bank of Scotland. The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics. Additionally, the Government of Canada honored Bell in 1997 with a C$100 gold coin, in tribute also to the 150th anniversary of his birth, and with a silver dollar coin in 2009 in honor of the 100th anniversary of flight in Canada. That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. Bell's image, and also those of his many inventions have graced paper money, coinage, and postal stamps in numerous countries worldwide for many dozens of years. Alexander Graham Bell was ranked 57th among the 100 Greatest Britons (2002) in an official BBC nationwide poll, and among the Top Ten Greatest Canadians (2004), and the 100 Greatest Americans (2005). In 2006, Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. Bell's name is still widely known and used as part of the names of dozens of educational institutes, corporate namesakes, street and place names around the world. Honorary degrees Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.D.s (Doctorate of Laws), two Ph.D.s, a D.Sc., and an M.D. : Gallaudet College (then named National Deaf-Mute College) in Washington, D.C. (Ph.D.) in 1880 University of Würzburg in Würzburg, Bavaria (Ph.D.) in 1882 Heidelberg University in Heidelberg, Germany (M.D.) in 1886 Harvard University in Cambridge, Massachusetts (LL.D.) in 1896 Illinois College, in Jacksonville, Illinois (LL.D.) in 1896, possibly 1881 Amherst College in Amherst, Massachusetts (LL.D.)

Anatolia Anatolia, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asian Turkey, thereby including the western part of the Armenian Highlands and northern Mesopotamia; its eastern and southern borders are coterminous with Turkey's borders. The ancient Anatolian peoples spoke the now-extinct Anatolian languages of the Indo-European language family, which were largely replaced by the Greek language during classical antiquity as well as during the Hellenistic, Roman, and Byzantine periods. The major Anatolian languages included Hittite, Luwian, and Lydian, while other, poorly attested local languages included Phrygian and Mysian. Hurro-Urartian languages were spoken in the southeastern kingdom of Mitanni, while Galatian, a Celtic language, was spoken in Galatia, central Anatolia. The Turkification of Anatolia began under the rule of the Seljuk Empire in the late 11th century and it continued under the rule of the Ottoman Empire between the late 13th and the early 20th century and it has continued under the rule of today's Republic of Turkey. However, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Neo-Aramaic, Armenian, Arabic, Laz, Georgian and Greek. Other ancient peoples in the region included Galatians, Hurrians, Assyrians, Hattians, Cimmerians, as well as Ionian, Dorian, and Aeolic Greeks. Geography Traditionally, Anatolia is considered to extend in the east to an indefinite line running from the Gulf of Alexandretta to the Black Sea, coterminous with the Anatolian Plateau. This traditional geographical definition is used, for example, in the latest edition of Merriam-Webster's Geographical Dictionary. Under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria and the Mesopotamian plain. Following the Armenian genocide, Western Armenia was renamed the Eastern Anatolia Region by the newly established Turkish government.

To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria and the Mesopotamian plain. Following the Armenian genocide, Western Armenia was renamed the Eastern Anatolia Region by the newly established Turkish government.

In 1941, with the First Geography Congress which divided Turkey into seven geographical regions based on differences in climate and landscape, the eastern provinces of Turkey were placed into the Eastern Anatolia Region, which largely corresponds to the historical region of Western Armenia (named as such after the division of Greater Armenia between the Roman/Byzantine Empire (Western Armenia) and Sassanid Persia (Eastern Armenia) in 387 AD). Vazken Davidian terms the expanded use of "Anatolia" to apply to territory in eastern Turkey that was formerly referred to as Armenia (which had a sizeable Armenian population before the Armenian genocide) an "ahistorical imposition" and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia." The highest mountain in the Eastern Anatolia Region (also the highest peak in the Armenian Highlands) is Mount Ararat (5123 m). The Euphrates, Araxes, Karasu and Murat rivers connect the Armenian Highlands to the South Caucasus and the Upper Euphrates Valley. Along with the Çoruh, these rivers are the longest in the Eastern Anatolia Region. Etymology The English-language name Anatolia derives from the Greek () meaning "the East" and designating (from a Greek point of view) eastern regions in general. The Greek word refers to the direction where the sun rises, coming from ἀνατέλλω anatello '(Ι) rise up,' comparable to terms in other languages such as "levant" from Latin levo 'to rise,' "orient" from Latin orior 'to arise, to originate,' Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine,' Aramaic מִדְנָח midnaḥ from דְּנַח denaḥ 'to rise, to shine.' The use of Anatolian designations has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies situated along the eastern coasts of the Aegean Sea, but also encompassing eastern regions in general. Such use of Anatolian designations was employed during the reign of Roman Emperor Diocletian (284–305), who created the Diocese of the East, known in Greek as the Eastern (Ανατολής / Anatolian) Diocese, but completely unrelated to the regions of Asia Minor. In their widest territorial scope, Anatolian designations were employed during the reign of Roman Emperor Constantine I (306–337), who created the Praetorian prefecture of the East, known in Greek as the Eastern (Ανατολής / Anatolian) Prefecture, encompassing all eastern regions of the Late Roman Empire and spaning from Thrace to Egypt. Only after the loss of other eastern regions during the 7th century and the reduction of Byzantine eastern domains to Asia Minor, that region became the only remaining part of the Byzantine East, and thus commonly referred to (in Greek) as the Eastern (Ανατολής / Anatolian) part of the Empire. In the same time, the Anatolic Theme (Ἀνατολικὸν θέμα / "the Eastern theme") was created, as a province (theme) covering the western and central parts of Turkey's present-day Central Anatolia Region, centered around Iconium, but ruled from the city of Amorium. The Latinized form "," with its -ia ending, is probably a Medieval Latin innovation.

Only after the loss of other eastern regions during the 7th century and the reduction of Byzantine eastern domains to Asia Minor, that region became the only remaining part of the Byzantine East, and thus commonly referred to (in Greek) as the Eastern (Ανατολής / Anatolian) part of the Empire. In the same time, the Anatolic Theme (Ἀνατολικὸν θέμα / "the Eastern theme") was created, as a province (theme) covering the western and central parts of Turkey's present-day Central Anatolia Region, centered around Iconium, but ruled from the city of Amorium. The Latinized form "," with its -ia ending, is probably a Medieval Latin innovation.

In 1941, with the First Geography Congress which divided Turkey into seven geographical regions based on differences in climate and landscape, the eastern provinces of Turkey were placed into the Eastern Anatolia Region, which largely corresponds to the historical region of Western Armenia (named as such after the division of Greater Armenia between the Roman/Byzantine Empire (Western Armenia) and Sassanid Persia (Eastern Armenia) in 387 AD). Vazken Davidian terms the expanded use of "Anatolia" to apply to territory in eastern Turkey that was formerly referred to as Armenia (which had a sizeable Armenian population before the Armenian genocide) an "ahistorical imposition" and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia." The highest mountain in the Eastern Anatolia Region (also the highest peak in the Armenian Highlands) is Mount Ararat (5123 m). The Euphrates, Araxes, Karasu and Murat rivers connect the Armenian Highlands to the South Caucasus and the Upper Euphrates Valley. Along with the Çoruh, these rivers are the longest in the Eastern Anatolia Region. Etymology The English-language name Anatolia derives from the Greek () meaning "the East" and designating (from a Greek point of view) eastern regions in general. The Greek word refers to the direction where the sun rises, coming from ἀνατέλλω anatello '(Ι) rise up,' comparable to terms in other languages such as "levant" from Latin levo 'to rise,' "orient" from Latin orior 'to arise, to originate,' Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine,' Aramaic מִדְנָח midnaḥ from דְּנַח denaḥ 'to rise, to shine.' The use of Anatolian designations has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies situated along the eastern coasts of the Aegean Sea, but also encompassing eastern regions in general. Such use of Anatolian designations was employed during the reign of Roman Emperor Diocletian (284–305), who created the Diocese of the East, known in Greek as the Eastern (Ανατολής / Anatolian) Diocese, but completely unrelated to the regions of Asia Minor. In their widest territorial scope, Anatolian designations were employed during the reign of Roman Emperor Constantine I (306–337), who created the Praetorian prefecture of the East, known in Greek as the Eastern (Ανατολής / Anatolian) Prefecture, encompassing all eastern regions of the Late Roman Empire and spaning from Thrace to Egypt.

In the same time, the Anatolic Theme (Ἀνατολικὸν θέμα / "the Eastern theme") was created, as a province (theme) covering the western and central parts of Turkey's present-day Central Anatolia Region, centered around Iconium, but ruled from the city of Amorium. The Latinized form "," with its -ia ending, is probably a Medieval Latin innovation.

The modern Turkish form Anadolu derives directly from the Greek name Aνατολή (Anatolḗ). The Russian male name Anatoly, the French Anatole and plain Anatol, all stemming from saints Anatolius of Laodicea (d. 283) and Anatolius of Constantinople (d. 458; the first Patriarch of Constantinople), share the same linguistic origin. Names The oldest known name for any region within Anatolia is related to its central area, known as the "Land of Hatti" – a designation that was initially used for the land of ancient Hattians, but later became the most common name for the entire territory under the rule of ancient Hittites. The first recorded name the Greeks used for the Anatolian peninsula, though not particularly popular at the time, was Ἀσία (Asía), perhaps from an Akkadian expression for the "sunrise" or possibly echoing the name of the Assuwa league in western Anatolia. The Romans used it as the name of their province, comprising the west of the peninsula plus the nearby Aegean Islands. As the name "Asia" broadened its scope to apply to the vaster region east of the Mediterranean, some Greeks in Late Antiquity came to use the name Asia Minor (Μικρὰ Ἀσία, Mikrà Asía), meaning "Lesser Asia" to refer to present-day Anatolia, whereas the administration of the Empire preferred the description Ἀνατολή (Anatolḗ "the East"). The endonym Ῥωμανία (Rōmanía "the land of the Romans, i.e. the Eastern Roman Empire") was understood as another name for the province by the invading Seljuq Turks, who founded a Sultanate of Rûm in 1077. Thus (land of the) Rûm became another name for Anatolia. By the 12th century Europeans had started referring to Anatolia as Turchia. During the era of the Ottoman Empire, mapmakers outside the Empire referred to the mountainous plateau in eastern Anatolia as Armenia. Other contemporary sources called the same area Kurdistan. Geographers have variously used the terms East Anatolian Plateau and Armenian Plateau to refer to the region, although the territory encompassed by each term largely overlaps with the other. According to archaeologist Lori Khatchadourian, this difference in terminology "primarily result[s] from the shifting political fortunes and cultural trajectories of the region since the nineteenth century." Turkey's First Geography Congress in 1941 created two geographical regions of Turkey to the east of the Gulf of Iskenderun-Black Sea line, the Eastern Anatolia Region and the Southeastern Anatolia Region, the former largely corresponding to the western part of the Armenian Highlands, the latter to the northern part of the Mesopotamian plain. According to Richard Hovannisian, this changing of toponyms was "necessary to obscure all evidence" of the Armenian presence as part of the policy of Armenian genocide denial embarked upon by the newly established Turkish government and what Hovannisian calls its "foreign collaborators." History Prehistoric Anatolia Human habitation in Anatolia dates back to the Paleolithic. Neolithic settlements include Çatalhöyük, Çayönü, Nevali Cori, Aşıklı Höyük, Boncuklu Höyük Hacilar, Göbekli Tepe, Norşuntepe, Kosk, and Mersin. Çatalhöyük (7.000 BCE) is considered the most advanced of these.

Neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the earliest attested branch of Indo-European, have been spoken in Anatolia since at least the 19th century BCE. Ancient Anatolia The earliest historical data related to Anatolia appear during the Bronze Age and continue throughout the Iron Age. The most ancient period in the history of Anatolia spans from the emergence of ancient Hattians, up to the conquest of Anatolia by the Achaemenid Empire in the 6th century BCE. Hattians and Hurrians The earliest historically attested populations of Anatolia were the Hattians in central Anatolia, and Hurrians further to the east. The Hattians were an indigenous people, whose main center was the city of Hattush. Affiliation of Hattian language remains unclear, while Hurrian language belongs to a distinctive family of Hurro-Urartian languages. All of those languages are extinct; relationships with indigenous languages of the Caucasus have been proposed, but are not generally accepted. The region became famous for exporting raw materials. Organized trade between Anatolia and Mesopotamia started to emerge during the period of the Akkadian Empire, and was continued and intensified during the period of the Old Assyrian Empire, between the 21st and the 18th centuries BCE. Assyrian traders were bringing tin and textiles in exchange for copper, silver or gold. Cuneiform records, dated circa 20th century BCE, found in Anatolia at the Assyrian colony of Kanesh, use an advanced system of trading computations and credit lines. Hittite Anatolia (18th–12th century BCE) Unlike the Akkadians and Assyrians, whose Anatolian trading posts were peripheral to their core lands in Mesopotamia, the Hittites were centered at Hattusa (modern Boğazkale) in north-central Anatolia by the 17th century BCE. They were speakers of an Indo-European language, the Hittite language, or nesili (the language of Nesa) in Hittite. The Hittites originated from local ancient cultures that grew in Anatolia, in addition to the arrival of Indo-European languages. Attested for the first time in the Assyrian tablets of Nesa around 2000 BCE, they conquered Hattusa in the 18th century BCE, imposing themselves over Hattian- and Hurrian-speaking populations. According to the widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites (along with the other Indo-European ancient Anatolians) were themselves relatively recent immigrants to Anatolia from the north. However, they did not necessarily displace the population genetically; they assimilated into the former peoples' culture, preserving the Hittite language. The Hittites adopted the Mesopotamian cuneiform script. In the Late Bronze Age, Hittite New Kingdom (c. 1650 BCE) was founded, becoming an empire in the 14th century BCE after the conquest of Kizzuwatna in the south-east and the defeat of the Assuwa league in western Anatolia. The empire reached its height in the 13th century BCE, controlling much of Asia Minor, northwestern Syria, and northwest upper Mesopotamia.

The empire reached its height in the 13th century BCE, controlling much of Asia Minor, northwestern Syria, and northwest upper Mesopotamia.

However, the Hittite advance toward the Black Sea coast was halted by the semi-nomadic pastoralist and tribal Kaskians, a non-Indo-European people who had earlier displaced the Palaic-speaking Indo-Europeans. Much of the history of the Hittite Empire concerned war with the rival empires of Egypt, Assyria and the Mitanni. The Egyptians eventually withdrew from the region after failing to gain the upper hand over the Hittites and becoming wary of the power of Assyria, which had destroyed the Mitanni Empire. The Assyrians and Hittites were then left to battle over control of eastern and southern Anatolia and colonial territories in Syria. The Assyrians had better success than the Egyptians, annexing much Hittite (and Hurrian) territory in these regions. Post-Hittite Anatolia (12th–6th century BCE) After 1180 BCE, during the Late Bronze Age collapse, the Hittite empire disintegrated into several independent Syro-Hittite states, subsequent to losing much territory to the Middle Assyrian Empire and being finally overrun by the Phrygians, another Indo-European people who are believed to have migrated from the Balkans. The Phrygian expansion into southeast Anatolia was eventually halted by the Assyrians, who controlled that region. Luwians Another Indo-European people, the Luwians, rose to prominence in central and western Anatolia circa 2000 BCE. Their language belonged to the same linguistic branch as Hittite. The general consensus amongst scholars is that Luwian was spoken across a large area of western Anatolia, including (possibly) Wilusa (Troy), the Seha River Land (to be identified with the Hermos and/or Kaikos valley), and the kingdom of Mira-Kuwaliya with its core territory of the Maeander valley. From the 9th century BCE, Luwian regions coalesced into a number of states such as Lydia, Caria, and Lycia, all of which had Hellenic influence. Arameans Arameans encroached over the borders of south-central Anatolia in the century or so after the fall of the Hittite empire, and some of the Syro-Hittite states in this region became an amalgam of Hittites and Arameans. These became known as Syro-Hittite states. Neo-Assyrian Empire From the 10th to late 7th centuries BCE, much of Anatolia (particularly the southeastern regions) fell to the Neo-Assyrian Empire, including all of the Syro-Hittite states, Tabal, Kingdom of Commagene, the Cimmerians and Scythians and swathes of Cappadocia. The Neo-Assyrian empire collapsed due to a bitter series of civil wars followed by a combined attack by Medes, Persians, Scythians and their own Babylonian relations. The last Assyrian city to fall was Harran in southeast Anatolia. This city was the birthplace of the last king of Babylon, the Assyrian Nabonidus and his son and regent Belshazzar. Much of the region then fell to the short-lived Iran-based Median Empire, with the Babylonians and Scythians briefly appropriating some territory. Cimmerian and Scythian invasions From the late 8th century BCE, a new wave of Indo-European-speaking raiders entered northern and northeast Anatolia: the Cimmerians and Scythians. The Cimmerians overran Phrygia and the Scythians threatened to do the same to Urartu and Lydia, before both were finally checked by the Assyrians.

However, the Hittite advance toward the Black Sea coast was halted by the semi-nomadic pastoralist and tribal Kaskians, a non-Indo-European people who had earlier displaced the Palaic-speaking Indo-Europeans.

Early Greek presence The north-western coast of Anatolia was inhabited by Greeks of the Achaean/Mycenaean culture from the 20th century BCE, related to the Greeks of southeastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BCE, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). Classical Anatolia In classical antiquity, Anatolia was described by Herodotus and later historians as divided into regions that were diverse in culture, language and religious practices. The northern regions included Bithynia, Paphlagonia and Pontus; to the west were Mysia, Lydia and Caria; and Lycia, Pamphylia and Cilicia belonged to the southern shore. There were also several inland regions: Phrygia, Cappadocia, Pisidia and Galatia. Languages spoken included the late surviving Anatolic languages Isaurian and Pisidian, Greek in Western and coastal regions, Phrygian spoken until the 7th century CE, local variants of Thracian in the Northwest, the Galatian variant of Gaulish in Galatia until the 6th century CE, Cappadocian and Armenian in the East, and Kartvelian languages in the Northeast. Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BCE in Lydia. The use of minted coins continued to flourish during the Greek and Roman eras. During the 6th century BCE, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty in Iran. In 499 BCE, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BCE, and the Ionian cities regained their independence. By the Peace of Antalcidas (387 BCE), which ended the Corinthian War, Persia regained control over Ionia. In 334 BCE, the Macedonian Greek king Alexander the Great conquered the peninsula from the Achaemenid Persian Empire. Alexander's conquest opened up the interior of Asia Minor to Greek settlement and influence. Following the death of Alexander and the breakup of his empire, Anatolia was ruled by a series of Hellenistic kingdoms, such as the Attalids of Pergamum and the Seleucids, the latter controlling most of Anatolia. A period of peaceful Hellenization followed, such that the local Anatolian languages had been supplanted by Greek by the 1st century BCE. In 133 BCE the last Attalid king bequeathed his kingdom to the Roman Republic, and western and central Anatolia came under Roman control, but Hellenistic culture remained predominant.

Early Greek presence The north-western coast of Anatolia was inhabited by Greeks of the Achaean/Mycenaean culture from the 20th century BCE, related to the Greeks of southeastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BCE, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). Classical Anatolia In classical antiquity, Anatolia was described by Herodotus and later historians as divided into regions that were diverse in culture, language and religious practices. The northern regions included Bithynia, Paphlagonia and Pontus; to the west were Mysia, Lydia and Caria; and Lycia, Pamphylia and Cilicia belonged to the southern shore. There were also several inland regions: Phrygia, Cappadocia, Pisidia and Galatia. Languages spoken included the late surviving Anatolic languages Isaurian and Pisidian, Greek in Western and coastal regions, Phrygian spoken until the 7th century CE, local variants of Thracian in the Northwest, the Galatian variant of Gaulish in Galatia until the 6th century CE, Cappadocian and Armenian in the East, and Kartvelian languages in the Northeast. Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BCE in Lydia.

Further annexations by Rome, in particular of the Kingdom of Pontus by Pompey, brought all of Anatolia under Roman control, except for the eastern frontier with the Parthian Empire, which remained unstable for centuries, causing a series of wars, culminating in the Roman-Parthian Wars. Early Christian Period After the division of the Roman Empire, Anatolia became part of the East Roman, or Byzantine Empire. Anatolia was one of the first places where Christianity spread, so that by the 4th century CE, western and central Anatolia were overwhelmingly Christian and Greek-speaking. For the next 600 years, while Imperial possessions in Europe were subjected to barbarian invasions, Anatolia would be the center of the Hellenic world. It was one of the wealthiest and most densely populated places in the Late Roman Empire. Anatolia's wealth grew during the 4th and 5th centuries thanks, in part, to the Pilgrim's Road that ran through the peninsula. Literary evidence about the rural landscape stems from the hagiographies of 6th century Nicholas of Sion and 7th century Theodore of Sykeon. Large urban centers included Ephesus, Pergamum, Sardis and Aphrodisias. Scholars continue to debate the cause of urban decline in the 6th and 7th centuries variously attributing it to the Plague of Justinian (541), and the 7th century Persian incursion and Arab conquest of the Levant. In the ninth and tenth century a resurgent Byzantine Empire regained its lost territories, including even long lost territory such as Armenia and Syria (ancient Aram). Medieval Period In the 10 years following the Battle of Manzikert in 1071, the Seljuk Turks from Central Asia migrated over large areas of Anatolia, with particular concentrations around the northwestern rim. The Turkish language and the Islamic religion were gradually introduced as a result of the Seljuk conquest, and this period marks the start of Anatolia's slow transition from predominantly Christian and Greek-speaking, to predominantly Muslim and Turkish-speaking (although ethnic groups such as Armenians, Greeks, and Assyrians remained numerous and retained Christianity and their native languages). In the following century, the Byzantines managed to reassert their control in western and northern Anatolia. Control of Anatolia was then split between the Byzantine Empire and the Seljuk Sultanate of Rûm, with the Byzantine holdings gradually being reduced. In 1255, the Mongols swept through eastern and central Anatolia, and would remain until 1335. The Ilkhanate garrison was stationed near Ankara. After the decline of the Ilkhanate from 1335 to 1353, the Mongol Empire's legacy in the region was the Uyghur Eretna Dynasty that was overthrown by Kadi Burhan al-Din in 1381. By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks. Smyrna fell in 1330, and the last Byzantine stronghold in Anatolia, Philadelphia, fell in 1390. The Turkmen Beyliks were under the control of the Mongols, at least nominally, through declining Seljuk sultans. The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids.

The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids.

The Osmanli ruler Osman I was the first Turkish ruler who minted coins in his own name in 1320s; they bear the legend "Minted by Osman son of Ertugrul". Since the minting of coins was a prerogative accorded in Islamic practice only to a sovereign, it can be considered that the Osmanli, or Ottoman Turks, had become formally independent from the Mongol Khans. Ottoman Empire Among the Turkish leaders, the Ottomans emerged as great power under Osman I and his son Orhan I. The Anatolian beyliks were successively absorbed into the rising Ottoman Empire during the 15th century. It is not well understood how the Osmanlı, or Ottoman Turks, came to dominate their neighbours, as the history of medieval Anatolia is still little known. The Ottomans completed the conquest of the peninsula in 1517 with the taking of Halicarnassus (modern Bodrum) from the Knights of Saint John. Modern times With the acceleration of the decline of the Ottoman Empire in the early 19th century, and as a result of the expansionist policies of the Russian Empire in the Caucasus, many Muslim nations and groups in that region, mainly Circassians, Tatars, Azeris, Lezgis, Chechens and several Turkic groups left their homelands and settled in Anatolia. As the Ottoman Empire further shrank in the Balkan regions and then fragmented during the Balkan Wars, much of the non-Christian populations of its former possessions, mainly Balkan Muslims (Bosnian Muslims, Albanians, Turks, Muslim Bulgarians and Greek Muslims such as the Vallahades from Greek Macedonia), were resettled in various parts of Anatolia, mostly in formerly Christian villages throughout Anatolia. A continuous reverse migration occurred since the early 19th century, when Greeks from Anatolia, Constantinople and Pontus area migrated toward the newly independent Kingdom of Greece, and also towards the United States, the southern part of the Russian Empire, Latin America, and the rest of Europe. Following the Russo-Persian Treaty of Turkmenchay (1828) and the incorporation of Eastern Armenia into the Russian Empire, another migration involved the large Armenian population of Anatolia, which recorded significant migration rates from Western Armenia (Eastern Anatolia) toward the Russian Empire, especially toward its newly established Armenian provinces. Anatolia remained multi-ethnic until the early 20th century (see the rise of nationalism under the Ottoman Empire). During World War I, the Armenian genocide, the Greek genocide (especially in Pontus), and the Assyrian genocide almost entirely removed the ancient indigenous communities of Armenian, Greek, and Assyrian populations in Anatolia and surrounding regions. Following the Greco-Turkish War of 1919–1922, most remaining ethnic Anatolian Greeks were forced out during the 1923 population exchange between Greece and Turkey. Of the remainder, most have left Turkey since then, leaving fewer than 5,000 Greeks in Anatolia today. Geology Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east.

True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and the Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin (Konya Ovasi). There are two mountain ranges in southern Anatolia: the Taurus and the Zagros mountains. Climate Anatolia has a varied range of climates. The central plateau is characterized by a continental climate, with hot summers and cold snowy winters. The south and west coasts enjoy a typical Mediterranean climate, with mild rainy winters, and warm dry summers. The Black Sea and Marmara coasts have a temperate oceanic climate, with cool foggy summers and much rainfall throughout the year. Ecoregions There is a diverse number of plant and animal communities. The mountains and coastal plain of northern Anatolia experience a humid and mild climate. There are temperate broadleaf, mixed and coniferous forests. The central and eastern plateau, with its drier continental climate, has deciduous forests and forest steppes. Western and southern Anatolia, which have a Mediterranean climate, contain Mediterranean forests, woodlands, and scrub ecoregions. Euxine-Colchic deciduous forests: These temperate broadleaf and mixed forests extend across northern Anatolia, lying between the mountains of northern Anatolia and the Black Sea. They include the enclaves of temperate rainforest lying along the southeastern coast of the Black Sea in eastern Turkey and Georgia. Northern Anatolian conifer and deciduous forests: These forests occupy the mountains of northern Anatolia, running east and west between the coastal Euxine-Colchic forests and the drier, continental climate forests of central and eastern Anatolia. Central Anatolian deciduous forests: These forests of deciduous oaks and evergreen pines cover the plateau of central Anatolia. Central Anatolian steppe: These dry grasslands cover the drier valleys and surround the saline lakes of central Anatolia, and include halophytic (salt tolerant) plant communities. Eastern Anatolian deciduous forests: This ecoregion occupies the plateau of eastern Anatolia. The drier and more continental climate is beneficial for steppe-forests dominated by deciduous oaks, with areas of shrubland, montane forest, and valley forest. Anatolian conifer and deciduous mixed forests: These forests occupy the western, Mediterranean-climate portion of the Anatolian plateau. Pine forests and mixed pine and oak woodlands and shrublands are predominant. Aegean and Western Turkey sclerophyllous and mixed forests: These Mediterranean-climate forests occupy the coastal lowlands and valleys of western Anatolia bordering the Aegean Sea. The ecoregion has forests of Turkish pine (Pinus brutia), oak forests and woodlands, and maquis shrubland of Turkish pine and evergreen sclerophyllous trees and shrubs, including Olive (Olea europaea), Strawberry Tree (Arbutus unedo), Arbutus andrachne, Kermes Oak (Quercus coccifera), and Bay Laurel (Laurus nobilis). Southern Anatolian montane conifer and deciduous forests: These mountain forests occupy the Mediterranean-climate Taurus Mountains of southern Anatolia.

Apple Inc. Apple Inc. is an American multinational technology company that specializes in consumer electronics, software and online services. Apple is the largest information technology company by revenue (totaling in 2021) and, as of January 2021, it is the world's most valuable company, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Jobs, Steve Wozniak and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II became a best seller. Apple went public in 1980, to instant financial success. The company went onto develop new computers featuring innovative graphical user interfaces, including the original Macintosh, announced in a critically acclaimed advertisement, "1984", directed by Ridley Scott. By 1985, the high cost of its products and power struggles between executives caused problems. Wozniak stepped back from Apple amicably, while Jobs resigned to found NeXT, taking some Apple employees with him. As the market for personal computers expanded and evolved throughout the 1990s, Apple lost considerable market share to the lower-priced duopoly of the Microsoft Windows operating system on Intel-powered PC clones (also known as "Wintel"). In 1997, weeks away from bankruptcy, the company bought NeXT to resolve Apple's unsuccessful operating system strategy and entice Jobs back to the company. Over the next decade, Jobs guided Apple back to profitability through a number of tactics including introducing the iMac, iPod, iPhone and iPad to critical acclaim, launching memorable advertising campaigns, opening the Apple Store retail chain, and acquiring numerous companies to broaden the company's product portfolio. Jobs resigned in 2011 for health reasons, and died two months later. He was succeeded as CEO by Tim Cook. Apple became the first publicly traded U.S. company to be valued at over $1 trillion in August 2018, then $2 trillion in August 2020, and most recently $3 trillion in January 2022. The company receives criticism regarding the labor practices of its contractors, its environmental practices, and its business ethics, including anti-competitive practices and materials sourcing. The company enjoys a high level of brand loyalty, and is ranked as one of the world's most valuable brands. History 1976–1980: Founding and incorporation Apple Computer Company was founded on April 1, 1976, by Steve Jobs, Steve Wozniak, and Ronald Wayne as a business partnership. The company's first product was the Apple I, a computer designed and hand-built entirely by Wozniak. To finance its creation, Jobs sold his only motorized means of transportation, a VW Bus, for a few hundred dollars, and Wozniak sold his HP-65 calculator for . Wozniak debuted the first prototype Apple I at the Homebrew Computer Club in July 1976.

To finance its creation, Jobs sold his only motorized means of transportation, a VW Bus, for a few hundred dollars, and Wozniak sold his HP-65 calculator for . Wozniak debuted the first prototype Apple I at the Homebrew Computer Club in July 1976.

The Apple I was sold as a motherboard with CPU, RAM, and basic textual-video chips—a base kit concept which would not yet be marketed as a complete personal computer. It went on sale soon after debut for . Wozniak later said he was unaware of the coincidental mark of the beast in the number 666, and that he came up with the price because he liked "repeating digits". Apple Computer, Inc. was incorporated on January 3, 1977, without Wayne, who had left and sold his share of the company back to Jobs and Wozniak for $800 only twelve days after having co-founded Apple. Multimillionaire Mike Markkula provided essential business expertise and funding of to Jobs and Wozniak during the incorporation of Apple. During the first five years of operations, revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980, yearly sales grew from $775,000 to $118 million, an average annual growth rate of 533%. The Apple II, also invented by Wozniak, was introduced on April 16, 1977, at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics and open architecture. While the Apple I and early Apple II models used ordinary audio cassette tapes as storage devices, they were superseded by the introduction of a -inch floppy disk drive and interface called the Disk II in 1978. The Apple II was chosen to be the desktop platform for the first "killer application" of the business world: VisiCalc, a spreadsheet program released in 1979. VisiCalc created a business market for the Apple II and gave home users an additional reason to buy an Apple II: compatibility with the office. Before VisiCalc, Apple had been a distant third place competitor to Commodore and Tandy. By the end of the 1970s, Apple had become the leading computer manufacturer in the United States. On December 12, 1980, Apple (ticker symbol "AAPL") went public selling 4.6 million shares at $22 per share ($.39 per share when adjusting for stock splits ), generating over $100 million, which was more capital than any IPO since Ford Motor Company in 1956. By the end of the day, 300 millionaires were created, from a stock price of $29 per share and a market cap of $1.778 billion. 1980–1990: Success with Macintosh A critical moment in the company's history came in December 1979 when Jobs and several Apple employees, including human–computer interface expert Jef Raskin, visited Xerox PARC in to see a demonstration of the Xerox Alto, a computer using a graphical user interface. Xerox granted Apple engineers three days of access to the PARC facilities in return for the option to buy 100,000 shares (5.6 million split-adjusted shares ) of Apple at the pre-IPO price of $10 a share. After the demonstration, Jobs was immediately convinced that all future computers would use a graphical user interface, and development of a GUI began for the Apple Lisa, named after Jobs's daughter.

After the demonstration, Jobs was immediately convinced that all future computers would use a graphical user interface, and development of a GUI began for the Apple Lisa, named after Jobs's daughter.

The Lisa division would be plagued by infighting, and in 1982 Jobs was pushed off the project. The Lisa launched in 1983 and became the first personal computer sold to the public with a GUI, but was a commercial failure due to its high price and limited software titles. Jobs, angered by being pushed off the Lisa team, took over the company's Macintosh division. Wozniak and Raskin had envisioned the Macintosh as low-cost-computer with a text-based interface like the Apple II, but a plane crash in 1981 forced Wozniak to step back from the project. Jobs quickly redefined the Macintosh as a graphical system that would be cheaper than the Lisa, undercutting his former division. Jobs was also hostile to the Apple II division, which at the time, generated most of the company's revenue. In 1984, Apple launched the Macintosh, the first personal computer to be sold without a programming language. Its debut was signified by "1984", a $1.5 million television advertisement directed by Ridley Scott that aired during the third quarter of Super Bowl XVIII on January 22, 1984. This is now hailed as a watershed event for Apple's success and was called a "masterpiece" by CNN and one of the greatest TV advertisements of all time by TV Guide. The advertisement created great interest in the original Macintosh, and sales were initially good, but began to taper off dramatically after the first three months as reviews started to come in. Jobs had made the decision to equip the original Macintosh with 128 kilobytes of RAM, attempting to reach a price point, which limited its speed and the software that could be used. The Macintosh would eventually ship for , a price panned by critics in light of its slow performance. In early 1985, this sales slump triggered a power struggle between Steve Jobs and CEO John Sculley, who had been hired away from Pepsi two years earlier by Jobs using the famous line, "Do you want to sell sugar water for the rest of your life or come with me and change the world?" Sculley decided to remove Jobs as the head of the Macintosh division, with unanimous support from the Apple board of directors. The board of directors instructed Sculley to contain Jobs and his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from his leadership role at Apple. Informed by Jean-Louis Gassée, Sculley found out that Jobs had been attempting to organize a boardroom coup and called an emergency meeting at which Apple's executive staff sided with Sculley and stripped Jobs of all operational duties. Jobs resigned from Apple in September 1985 and took a number of Apple employees with him to found NeXT.

Jobs resigned from Apple in September 1985 and took a number of Apple employees with him to found NeXT.

Wozniak had also quit his active employment at Apple earlier in 1985 to pursue other ventures, expressing his frustration with Apple's treatment of the Apple II division and stating that the company had "been going in the wrong direction for the last five years". Despite Wozniak's grievances, he officially remained employed by Apple, and to this day continues to work for the company as a representative, receiving a stipend estimated to be $120,000 per year for this role. Both Jobs and Wozniak remained Apple shareholders after their departures. After the departures of Jobs and Wozniak, Sculley worked to improve the Macintosh in 1985 by quadrupling the RAM and introducing the LaserWriter, the first reasonably priced PostScript laser printer. PageMaker, an early desktop publishing application taking advantage of the PostScript language, was also released by Aldus Corporation in July 1985. It has been suggested that the combination of Macintosh, LaserWriter and PageMaker was responsible for the creation of the desktop publishing market. This dominant position in the desktop publishing market allowed the company to focus on higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Newer models selling at higher price points offered higher profit margin, and appeared to have no effect on total sales as power users snapped up every increase in speed. Although some worried about pricing themselves out of the market, the high-right policy was in full force by the mid-1980s, notably due to Jean-Louis Gassée's mantra of "fifty-five or die", referring to the 55% profit margins of the Macintosh II. This policy began to backfire in the last years of the decade as desktop publishing programs appeared on PC clones that offered some or much of the same functionality of the Macintosh, but at far lower price points. The company lost its dominant position in the desktop publishing market and estranged many of its original consumer customer base who could no longer afford their high-priced products. The Christmas season of 1989 was the first in the company's history to have declining sales, which led to a 20% drop in Apple's stock price. During this period, the relationship between Sculley and Gassée deteriorated, leading Sculley to effectively demote Gassée in January 1990 by appointing Michael Spindler as the chief operating officer. Gassée left the company later that year. 1990–1997: Decline and restructuring The company pivoted strategy and in October 1990 introduced three lower-cost models, the Macintosh Classic, the Macintosh LC, and the Macintosh IIsi, all of which saw significant sales due to pent-up demand. In 1991, Apple introduced the hugely successful PowerBook with a design that set the current shape for almost all modern laptops. The same year, Apple introduced System 7, a major upgrade to the Macintosh operating system, adding color to the interface and introducing new networking capabilities. The success of the lower-cost Macs and PowerBook brought increasing revenue.

It has been suggested that the combination of Macintosh, LaserWriter and PageMaker was responsible for the creation of the desktop publishing market. This dominant position in the desktop publishing market allowed the company to focus on higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Newer models selling at higher price points offered higher profit margin, and appeared to have no effect on total sales as power users snapped up every increase in speed. Although some worried about pricing themselves out of the market, the high-right policy was in full force by the mid-1980s, notably due to Jean-Louis Gassée's mantra of "fifty-five or die", referring to the 55% profit margins of the Macintosh II. This policy began to backfire in the last years of the decade as desktop publishing programs appeared on PC clones that offered some or much of the same functionality of the Macintosh, but at far lower price points. The company lost its dominant position in the desktop publishing market and estranged many of its original consumer customer base who could no longer afford their high-priced products. The Christmas season of 1989 was the first in the company's history to have declining sales, which led to a 20% drop in Apple's stock price. During this period, the relationship between Sculley and Gassée deteriorated, leading Sculley to effectively demote Gassée in January 1990 by appointing Michael Spindler as the chief operating officer. Gassée left the company later that year. 1990–1997: Decline and restructuring The company pivoted strategy and in October 1990 introduced three lower-cost models, the Macintosh Classic, the Macintosh LC, and the Macintosh IIsi, all of which saw significant sales due to pent-up demand. In 1991, Apple introduced the hugely successful PowerBook with a design that set the current shape for almost all modern laptops. The same year, Apple introduced System 7, a major upgrade to the Macintosh operating system, adding color to the interface and introducing new networking capabilities. The success of the lower-cost Macs and PowerBook brought increasing revenue.

Wozniak had also quit his active employment at Apple earlier in 1985 to pursue other ventures, expressing his frustration with Apple's treatment of the Apple II division and stating that the company had "been going in the wrong direction for the last five years". Despite Wozniak's grievances, he officially remained employed by Apple, and to this day continues to work for the company as a representative, receiving a stipend estimated to be $120,000 per year for this role. Both Jobs and Wozniak remained Apple shareholders after their departures.

For some time, Apple was doing incredibly well, introducing fresh new products and generating increasing profits in the process. The magazine MacAddict named the period between 1989 and 1991 as the "first golden age" of the Macintosh. The success of Apple's lower-cost consumer models, especially the LC, also led to the cannibalization of their higher-priced machines. To address this, management introduced several new brands, selling largely identical machines at different price points, aimed at different markets: the high-end Quadra models, the mid-range Centris line, and the consumer-marketed Performa series. This led to significant market confusion, as customers did not understand the difference between models. The early 1990s also saw the discontinuation of the Apple II series, which was expensive to produce, and the company felt was still taking sales away from lower-cost Macintosh models. After the launch of the LC, Apple began encouraging developers to create applications for Macintosh rather than Apple II, and authorized salespersons to direct consumers towards Macintosh and away from Apple II. The Apple IIe was discontinued in 1993. Throughout this period, Microsoft continued to gain market share with its Windows graphical user interface that it sold to manufacturers of generally less expensive PC clones. While the Macintosh was more expensive, it offered a more tightly integrated user experience, but the company struggled to make the case to consumers. Apple also experimented with a number of other unsuccessful consumer targeted products during the 1990s, including digital cameras, portable CD audio players, speakers, video game consoles, the eWorld online service, and TV appliances. Most notably, enormous resources were invested in the problem-plagued Newton tablet division, based on John Sculley's unrealistic market forecasts. personal computers, while Apple was delivering a richly engineered but expensive experience. Apple relied on high profit margins and never developed a clear response; instead, they sued Microsoft for using a GUI similar to the Apple Lisa in Apple Computer, Inc. v. Microsoft Corp. The lawsuit dragged on for years before it was finally dismissed. The major product flops and the rapid loss of market share to Windows sullied Apple's reputation, and in 1993 Sculley was replaced as CEO by Michael Spindler. With Spindler at the helm Apple, IBM, and Motorola formed the AIM alliance in 1994 with the goal of creating a new computing platform (the PowerPC Reference Platform; PReP), which would use IBM and Motorola hardware coupled with Apple software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind and thus counter the dominance of Windows. The same year, Apple introduced the Power Macintosh, the first of many Apple computers to use Motorola's PowerPC processor. In the wake of the alliance, Apple opened up to the idea of allowing Motorola and other companies to build Macintosh clones. Over the next two years, 75 distinct Macintosh clone models were introduced. However, by 1996 Apple executives were worried that the clones were cannibalizing sales of their own high-end computers, where profit margins were highest.
