A Polish-born mathematician who worked in symbolic logic, set theory and computation theory, Emil Leon Post received his doctorate from Columbia in 1920 for a dissertation proving the consistency of the propositional calculus described in Whitehead and Russell's Principia mathematica. He joined the faculty at City College of the City University of New York in 1932, where he remained until his death in 1954. Although illness continually interrupted Post's career, he made important contributions to the concepts of completeness and consistency and to recursive functions, foundational to modern computing theory. In 1936, he introduced the concept of a "Post machine," a sort of precursor to the von Neumann's notion of a program. The Post Papers consist of 8 linear feet of professional correspondence, research notes, and papers, to which have been added a small number of items of biographical interest.

William S. Willis Jr. (1921-1983), anthropologist and ethnohistorian, contributed significantly to the understanding of the dynamics of inter-cultural exchange in a multicultural context. After receiving his doctorate from Columbia University, he was hired as the first African American professor of Anthropology at Southern Methodist University. Upon resigning in protest from SMU in 1972, he returned to teach at Columbia University until 1975. His final years were spent studying Boasian anthropology. The collection includes correspondence, lecture notes, manuscripts of Willis' writings, and working notes. Of note, are the memos concerning his leaving Southern Methodist University and his extensive research notes on Franz Boas' views on race relations in America.

In addition to correspondence relating to poultry genetics and egg production, there are significant notes concerning breeding records, heredity, and race genetics. There are 42 class notebooks kept by Goodale, and 62 volumes of Mount Hope Poultry Farm family, hatching, mating records for the period 1918 to 1956. The collection includes photographs, glass-lantern lecture slides, and artifacts of poultry feathers.

The American Eugenics Society Records is a small, selective collection offering information on various periods of the Society's development, including correspondence, membership records, and formal and informal material on its history. Of particular interest are the records of the Society's numerous committees, including the Executive Education, Population Genetics Research, Legislative, and local and state committees, and documentation of AES educational initiatives at state fairs and eugenic health exhibits and contests, especially the Fitter Family Contests. A scrapbook containing 97 images of Fitter Family and eugenic health exhibits, 1924-1926, provides valuable visual information of AES activities. One series in the collection relates to the numerous Princeton Conferences and to a genealogical survey of the populations of Shutesbury and Leverett, Massachusetts, and there is also material on the Population Council. The collection largely revolves around Frederick Osborn, the moving force in the Society for most of its later history, and it includes approximately 100 papers written or delivered by Osborn concerning eugenics, genetics, or population related topics. This note is currently under review for revision.
