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.

The United States Indian School at Carlisle, Pa., was founded by Gen. Richard Henry Pratt in 1879, and served as a model for government boarding schools for Indians until its closure in 1918. Over 10,000 students enrolled at the Carlisle Training School during its 39 years, where, separated from their native cultures, the students were prepared for work in industrial and manual labor and socialized into "civilized" life. Given new white names to replace their Indian ones, the students were prohibited from speaking their native languages, were instructed in Christianity, and were fed, clothed, and housed under strict military discipline. The 27 photographs in the Speck-Choate Photograph Collection were taken by J. N. Choate, a local commercial photographer in Carlisle, Pa., and collected by the anthropologist Frank G. Speck. Choate advertised "Photographs of all the Indian Chiefs that have visited the Indian Training School at Carlisle Barracks, also of children in native and school costumes" and were intended to document the benefits of civilization that the school brought to Indians. Typical images include "before and after" shots of students in native dress and school uniforms, the school band, and shots of the students at work in the saddle shop and making shoes. Choate also took a number of images of visiting chiefs in traditional dress, including the Lakota chief Spotted Tail, and the Cheyennes Man on Cloud and Mad Wolf. One photograph depicts Richard Henry Pratt seated with Quaker supporters. Among the tribes represented are the Lakota, Laguna, Cheyenne, Creek, Lipan, and Pueblo.
