Collection: The North American Indian Photography of Edward Curtis - Edward S. Curtis, a professional photographer in Seattle, devoted his life to documenting what was perceived to be a vanishing race. His monumental publication The North American Indian presented to the public an extensive ethnographical study of numerous tribes, and his photographs remain memorable icons of the American Indian. The Smithsonian Libraries holds a complete set of this work, which includes photogravures on tissue, donated by Mrs. Edward H. Harriman, whose husband had conducted an expedition to Alaska with Curtis in 1899.
