Trained as an anthropologist under Frank Speck at the University of Pennsylvania, the ethnohistorian George Snyderman (1908- ) spent his career studying Seneca Indian religion, history, and culture. Snyderman edited the previously unpublished diaries of Halliday Jackson and John Phillips, Quaker missionaries to the Senecas in the late 18th and early 19th century. The Snyderman Papers includes a small volume of correspondence, along with manuscripts of works by Snyderman and colleagues, and copies of primary source materials pertaining to Seneca history. Of particular interest is his correspondence with anthropologists William N. Fenton, Merle Deardorff, and Frank Speck and with his Seneca consultant Clara Redeye and her daughter, Helen Harris, and photographs of the Allegany Senecas taken by Fenton and Speck.

The Anthony F. C. Wallace Papers include correspondence to and from 20th century anthropologists, ethnologists, historians, linguists, and psychiatrists and provides a wealth of resources for the study of technological and social change, American Indians, culture and personality, revitalization movements, the anthropological study of religion, and the cultural and biological bases of behavior. In addition to Wallace's correspondence, research notes, and drafts, the collection includes Wallace family correspondence and photographs, as well as Wallace's writings from childhood through recent years.
