A Yale-educated ethnographer, William Fenton devoted most of his career to study of the Haudenosaunee. Receiving his doctorate in 1937, Fenton worked with the Bureau of American Ethnology for a number of years before becoming Director of the New York State Museum and professor at SUNY Albany. The Fenton Papers covers all aspects of William Fenton's professional life, documenting his varied positions as community worker for the New York Agency of the U.S. Indian Service, 1935-1937 (accounts, reports, correspondence); associate anthropologist and senior ethnologist in the Bureau of American Ethnology, 1939-1951 (includes notebooks, letters from the field); Executive Secretary of Anthropology and Psychology, National Academy of Sciences-National Research Council, 1952-1954; and Assistant Commissioner, New York State Museum and Science Service, 1954-1968.

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.

The papers contain correspondence, research and teaching notes, data (card and slip) files, published and unpublished manuscripts by Lounsbury and others, books and reprints, sound recordings, and computer programs and files. Correspondents include: William N. Fenton, Mary R. Haas, William C. Sturtevant, Morris Swadesh, and Carl F. Voegelin. Roughly one-quarter of the collection relates to Iroquoian languages and includes much WPA Oneida Project material. Research into the Cherokee language, South American languages, and kinship structures is also well represented. Floyd Lounsbury's wife, Masako Yokoyama Lounsbury, is represented by a smaller amount of material relating to linguistic research in Shanghai and research on Quechua.
