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 Mary Rosamond Haas papers are extensive, including correspondence, research notes, field notes, texts, lexical slip files, audio recordings, photographs, reprints and more, covering more than 100 languages of North America and Southeast Asia. Of particular value are notes and audio recordings from fieldwork from the 1930s on Ditidaht, Tunica, Natchez and Muscogee, work toward pedagogical materials for Thai, and groundbreaking comparative studies of several language families of North America.
