Carlos Montezuma (Wassaja) (1866-1923) was a Yavapai Apache doctor who served as the resident physician at the Carlisle Indian School between 1893-1895. After leaving the Carlisle Indian School, he opened a private practice in Chicago, and became a well-known activist for Native Americans rights.
The Carlos Montezuma Papers at the Newberry Library, Chicago, Illinois were received by that institution in 1984. The collection includes correspondence, published and unpublished writings, clippings, and photographs related to the Carlisle Indian School. The materials have been completely digitized by the Newberry, and are freely available. Researchers interested in Montezuma's relationship with the Carlisle Indian School are advised to consult records linked to some of the school's administrators, including (but not limited to) Richard Henry Pratt, A.J. Standing, and Estelle Reel, as well as those materials related to Carlisle and Pennsylvania.
