this american inventor created the cotton gin and interchangeable parts
Eli Whitney Whitney is most famous for two innovations which came to have significant impacts on the United States in the mid-19th century: the cotton gin (1793) and his advocacy of interchangeable parts. In the South, the cotton gin revolutionized the way cotton was harvested and reinvigorated slavery. In the North the adoption of interchangeable parts revolutionized the manufacturing industry, and contributed greatly to the U.S. victory in the Civil War.[5]
History of Manchester Manchester now developed as the natural distribution centre for raw cotton and spun yarn, and a marketplace and distribution centre for the products of this growing textile industry. Richard Arkwright is credited as the first to erect a cotton mill in the city. His first experiment, installing a Newcomen steam engine to pump water for a waterwheel failed, but he next adapted a Watt steam engine to directly operate the machinery. The result was the rapid spread of cotton mills throughout Manchester itself and in the surrounding towns. To these must be added bleach works, textile print works, and the engineering workshops and foundries, all serving the cotton industry. During the mid-19th century Manchester grew to become the centre of Lancashire's cotton industry and was dubbed "Cottonopolis", and a branch of the Bank of England was established in 1826.
