Research on Inuit clothing

There is a long historical tradition of research on Inuit clothing across many fields. Since Europeans first made contact with the Inuit in the 16th century, documentation and research on Inuit clothing has included artistic depictions, academic writing, studies of effectiveness, and museum collections. Historically, European images of Inuit people were sourced from the clothing worn by Inuit who travelled to Europe (whether voluntarily or as captives), clothing brought to museums by explorers, and from written accounts of travels to the Arctic. 
From the 18th century until the mid-20th century, explorers, missionaries, and academics described the Inuit clothing system in numerous memoirs and dissertations. After a decline in the 1940s, serious scholarship of Inuit clothing did not pick up again until the 1980s, at which time the focus shifted to in-depth studies of the clothing of specific Inuit and Arctic groups, as well as academic collaborations with Inuit people and their communities. Scientific analysis of Inuit garments have often focused on the effectiveness of Inuit skin clothing as cold-weather clothing. Many museums, particularly in Canada, Denmark, the United Kingdom, and the United States, have extensive collections of historical Inuit garments, often acquired during Arctic explorations undertaken in the 19th and early 20th centuries. 
Painting, printing, and photography.
Inuit skin clothing has long been of interest to artists and academics of all kinds. Europeans interested in the Inuit and their culture began to create artistic depictions of Inuit clothing as early as the 16th century. These images were typically sourced from the clothing worn by Inuit who travelled to Europe (whether voluntarily or as captives), clothing brought to museums by explorers, and from written accounts of travels to the Arctic. The earliest of these was a series of illustrated broadsides printed after an Inuit mother and child from Labrador were brought to the European Low Countries in 1566. In 1577, the privateer Martin Frobisher brought three Inuit – Kalicho, Arnaq and Nutaaq – to England as captives, and the painter John White produced detailed watercolor portraits of them. A 1654 painting by Salomon von Hauen, commissioned at Bergen, Norway, is the oldest known portrait depicting the traditional clothing of the Kalaallit people of Greenland. It depicts a group of four Kalaallit who were kidnapped by a Danish trade ship, each wearing traditional skin clothing. Numerous other paintings and engravings of Inuit people and their clothing were created over the following centuries.
When modern techniques such as lithography and photography became available in the mid-19th century, it allowed for an even wider dissemination of images of Inuit clothing, especially in illustrated magazines. Around 1860, a series of Danish publications about Inuit culture and clothing from Greenland included lithographs created by Inuit artists.
Academic writing and studies.
One of the oldest major works describing Inuit clothing in detail is the 1741 book ("The Old Greenland's New Perlustration or Natural History") by Danish missionary Hans Egede. The book contained detailed drawings and descriptions of women's clothing from observations made during his fifteen years living in Greenland. Starting in the 18th century, the diaries and other writings of Arctic explorers and traders, and to a lesser extent, academics, provided further detail about daily Inuit clothing. As contact between outsiders and Inuit increased, so did the level of detail in their writing. The clothing of the Caribou Inuit and Copper Inuit during this time is particularly well-documented in such writing. 
Anthropological study of Inuit culture and clothing by Danish, American, and Canadian scholars was common in the 19th and early 20th centuries. These sources focused on the physical aspects of Inuit clothing that enabled survival in the extreme Arctic environment, as well as the technical aspects involved in garment production. Ethnographers such as John Murdoch published descriptions of Inuit clothing with detailed illustrations as early as 1892, based on fieldwork in northwest Alaska. Canadian explorers Diamond Jenness and Vilhjalmur Stefansson lived with the Inuit during the Canadian Arctic Expedition, 1913–1916, adopting Inuit clothing and making in-depth studies of its construction.
Danish archaeologist Gudmund Hatt wrote a dissertation on his theory of Inuit origins, published in 1914, which was based on his in-depth study of Inuit clothing in museums across Europe. Later scholarship disputed his migration theory, but his studies of Inuit clothing, with their elaborate images drawn by his wife Emilie Demant Hatt, have been described as "groundbreaking in their meticulousness and scope". By approximately 1940, serious scholarship of Arctic clothing had tapered off.
Scholarship of Inuit clothing did not pick up again until the 1980s and 1990s, beginning with fieldwork conducted by Inuit clothing expert Bernadette Driscoll-Engelstad, and supported by accounts created by northern seamstresses. By then, the style of grand cross-cultural study pioneered by Hatt had fallen out of the mainstream, with modern scholars preferring to make in-depth studies of the clothing of specific Inuit and Arctic groups. 
Around this time, academic collaborations with Inuit people and their communities became a dominant form of scholarship on the topic; these collaborations have been important for the preservation of traditional knowledge. For example, the Igloolik Research Centre in Nunavut, Canada, archives interviews with Inuit elders to preserve their traditional knowledge, including information about traditional clothing production techniques. In the 1980s, Driscoll-Engelstad travelled to museums in Europe and Canada with Inuit seamstresses to study historical garments. Their work has been credited with having "triggered a renaissance in clothing manufacture in some Canadian communities." Around the same time, Arctic anthropologist Susan Kaplan began to work with North Greenland Inuit and Labrador Inuit at the Peary–MacMillan Arctic Museum on similar fieldwork. The documentary film "Piqutingit: What Belongs to lnuit", released in 2006, documents the journey of a group of Inuit elders to museums in Toronto, Ottawa, New York, Philadelphia, and Washington.
Modern scientific research.
Archaeology.
Archaeology is a major source of knowledge about the history of Inuit clothing, primarily in the form of artifacts such as tools for skin preparation and sewing, as well as art objects. More rarely, scraps of frozen skin garments or even whole garments are found at archaeological sites. Some of these items come from the earlier Dorset culture era, but the majority are from the Thule culture era of approximately 1000 to 1600 CE. Research on historical garments shows evidence for the historical consistency of Inuit skin clothing. 
One of the most notable archaeological finds related to skin clothing was the 1972 discovery of a group of eight well-preserved and fully dressed mummies at Qilakitsoq, an archaeological site on Nuussuaq Peninsula, Greenland. The outer garments were made from sealskin, and the inner parkas constructed from the skins of at least five different types of water birds. The mummies have been carbon-dated to , and analysis indicates that the skin garments they were found in were prepared and sewn in the same manner as modern skin clothing from the Kalaallit people of the region. Anatomical analysis of the mummies' teeth and biochemical analysis of the sealskin garments indicated that preparation methods have changed little over the past 500 years, including the use of teeth to soften skin for sewing.
Archaeological digs in Utqiaġvik, Alaska from 1981 to 1983 uncovered the earliest known samples of caribou and polar bear skin clothing of the Kakligmiut people, carbon-dated to c. 1510. The construction of these garments indicates that Kakligmiut garments underwent little change between approximately 1500–1850. 
Analysis of effectiveness.
Another significant area of research on Inuit skin clothing has been its effectiveness, especially as contrasted with modern winter clothing made from synthetic materials. Despite extensive oral testimony on the effectiveness of skin garments from Inuit elders, as well as written records produced by Arctic explorers as early as the 18th century, little direct research was performed on the topic until the 1990s. A study published in 1995 compared caribou-skin clothing to mass-produced military and expedition gear, and found that the Inuit garments were significantly warmer, and provided a greater degree of perceived comfort than the mass-produced items. Further studies have shown that the traditional Inuit hood, with its distinctive ruff of irregular fur, is the most efficient system for preventing heat transfer from the face in the cold, windy environment of the Arctic.
Scanning electron microscopy shows that the unique microscopic structure of caribou and seal hairs contribute to their effectiveness. Caribou hairs have a round cross-section, with an irregular surface and an internal structure "reminiscent of 'bubble-wrap, which handily traps warm air inside each hair as well as between adjacent hairs. The keratin walls between cells are thin but tough, making individual hairs lightweight but resilient to damage. In contrast, seal hairs have a flattened cross-section and are solid throughout. The scales on the outside of each hair overlap only in one direction, resulting in a smooth surface. As a result, seal hair is less insulating than caribou hair, but is excellent at repelling water.
Museum collections.
Many museums, particularly in Canada, Denmark, the United Kingdom, and the United States, have extensive collections of historical Inuit garments. The ceremonial dance clothing of the Copper Inuit is particularly well-represented in museums worldwide. The British Museum in London holds some of the oldest surviving Inuit fur clothing, collected by Captain William Edward Parry at Igloolik in the early 1820s. The Smithsonian Institution in Washington, D.C. has an extensive collection of Arctic materials from Canada and Alaska, including clothing, obtained beginning in 1850. Norwegian polar explorer Roald Amundsen acquired numerous Inuit artifacts, including clothing, during his voyage to the Northwest Passage on the "Gjøa" from 1903–1906, which he brought to the Ethnographgic Museum of Norway (now the Museum of Cultural History, Oslo). 
Acquisition of Inuit clothing for display began early in Denmark: in the 1620s, Danish naturalist Ole Worm collected samples of Greenlandic Inuit clothing in his cabinet of curiosities, the "Museum Wormianum". Although much of his collection was later acquired by the National Museum of Denmark, the garments he collected are now lost. The skin garment collection of the National Museum is one of the most extensive in the world, containing over 2100 historic skin clothing items from various Arctic cultures, with examples from as early as 1830. In his capacity as head of antiquities at the museum, antiquarian Christian Jürgensen Thomsen was particularly active in increasing the size of this collection in the 1840s. In 1851, Finnish ethnographer Henrik Johan Holmberg acquired several hundred artifacts, including skin garments, from the Alaskan Inuit and the Indigenous peoples of the Pacific Northwest Coast, which Thomsen acquired from him for the Danish National Museum in 1852. Noted anthropological expeditions such as the Gjøa Expedition (1903–1906) and the Fifth Thule Expedition (1921–1924) brought back and donated to the museum a combined total of over 800 North American Inuit garments.
Despite the existence of these extensive collections, throughout the 20th century, many museums rarely displayed Inuit clothing and artifacts. In North America, this only began to change in the 1980s, with the debut of several notable exhibitions. In 1980, the Winnipeg Art Gallery presented "The lnuit Amautik: I like my hood to be full", an exhibit focusing on the women's parka, the "amauti". In 1982, the Smithsonian Museum presented a comprehensive exhibit of Inuit artifacts and clothing, entitled "lnua: Spirit World of the Bering Sea Eskimo". In 1994, the Canadian Museum of Civilization, which owns the largest collection of Inuit clothing in North America, featured examples of clothing by the Inuit, Dene, and Nlaka'pamux First Nations in an exhibition titled "Threads of the Land", in cooperation with Inuit seamstresses.
Preservation of skin clothing, even in a museum, is difficult, because the organic materials used to make the garments are subject to decay, hair loss, and insect infestation if not preserved with enormous care. Historically, garments were often simply displayed in museums in the open without any protection whatsoever. Storage areas were often poorly-maintained, dusty, and full of insects. These poor display and storage methods led to the deterioration or outright loss of many items. Since the 1960s, methods for storage of cultural heritage objects have become increasingly sophisticated. Skin garments today are typically kept in cold storage facilities when not on display. When on the museum floor, they are kept in airtight showcases with controlled temperature and light intensity. Although protective measures are important, research has found that the original preparation process, as well as previous ordinary use of the garments, are also significant factors which influence the degree of deterioration in skin garments. Driscoll-Engelstad suggested that museums should work with Inuit artisans to repair damaged clothing and artifacts.
Increased access to travel and digital communication technologies like the internet have made it easier for museum curators to collaborate with Inuit communities. This can take the form of providing material to the community for cultural heritage programs, or arranging training so community members can make recordings of knowledge from the oral tradition. Many museums have created digital exhibits to provide greater access to their collections. Collaborative projects such as Skin Clothing Online, from the National Museum of Denmark, Greenland National Museum, and Museum of Cultural History, Oslo, have made thousands of high-resolution images and dozens of 3D scans of hundreds of pieces of skin clothing from various Arctic cultures freely accessible to researchers and the general public.
