A shadowy figure at best, the artist Antonio Zeno Shindler worked at the Smithsonian Institution from after the Civil War until the turn of the 20th century, specializing in ethnographic subjects. He was responsible for printing or taking a large number of photographs of American Indians exhibited there in 1869. The 95 studio portraits in the Shindler Collection were part of a suite of 301 images that comprised the first photographic exhibition at the Smithsonian, and that are documented in the catalogue Photographic Portraits of North American Indians in the Gallery of the Smithsonian Institution (1867). The individuals depicted were members of delegations sent to Washington during the years 1852, 1857-1858, and 1867-1869 from the following nations: Cherokee, Cheyenne, Chippewa, Choctaw, Dakota Sioux (Brule, Miniconjou, Sans Arc, Santee, Sisseton, Two-Kettle, Yankton), Osage, Pawnee, Ponca, Potawatomi, Sac and Fox, Seminole, and Ute. Shindler printed the earlier photographs (mostly taken by the McClees Gallery) and was photographer for the later delegations.
