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.

A botanist and historian of science at the University of Pennsylvania, Conway Zirkle published on the history of evolutionary thought and genetics, with a particular interest in the discipline as practiced in the Soviet Union. The Zirkle Papers consist of approximately one linear foot of materials accrued by Zirkle during research for his book on Lysenko-era biology in the Soviet Union, The Death of Science in Russia (1949). Among the miscellaneous materials in the collection are four volumes (0.5 linear feet) of pressed specimens of ferns and algae.

Frederick Henry Osborn was an administrator, humanist, and scientist. This collection includes letters, diaries, reports, speeches, drafts of articles and books, oral history interviews, and photographs. There are diaries and letters for his service in Europe with the American Red Cross during World War I. There are some letters and documents, such as patent applications and plans for inventions, from his "business career" period prior to 1928, after which he became a research associate at the American Museum of Natural History studying anthropology and population. This study led to his later important contributions to the redirection of eugenics study in the U.S. and the reorganization of the American Eugenics Society. His other related organizational work and publications relating to human and population genetics are also documented in this collection. There is significant material (letters, diaries, reports) related to Osborn's World War II contributions as the chairman of the Civilian Committee on Selective Service in 1940, and as head of the Morale Branch of the U.S. Army (later, the Information and Education Division of Special Services) in 1941. Also included are important documents, especially his diary, from his work as deputy representative on the U.S. Atomic Energy Commission and the U.N. Commission for Conventional Armaments. His letters, writings, and speeches relating to foreign policy are extensive, spanning the period from the 1940s until his death, much of it from the Vietnam War years. The correspondence with Kathleen Harris is particularly rich in this respect. There is family correspondence reflecting his dynamic philosophy of life, with long series of letters to his parents (1917-1945) and to his children and grandchildren. His later civic and regional interests, as a long-time resident of Garrison, N.Y., are evidenced in the work he did on the Palisades Interstate Park Commission.

Arthur J. Cain is an evolutionary biologist whose research interests have included genetics, natural selection, biogeography, and systematics. Based at Oxford University and, later, the University of Liverpool, much of Cain's research was field-based, focusing on terrestrial gatsropods. This collection contains correspondence, grant applications, reports, programs for scientific meetings, unpublished papers and lectures, research notes, charts, graphs, maps, and manuscript reviews of journal articles and books. The Cain Papers is divided into three series: I. Correspondence ; II. Subject Files ; and, III. Papers by Colleagues. Arrangement is alphabetical by folder title, and chronological within each folder.

Between 1968 and 1978, the historian of science Horace Freeland Judson conducted extensive oral history interviews with biochemists and molecular biologists relating to the development of their field. The correspondence, transcripts of interviews, and taped interviews that comprise the Judson collection formed the research material used by Judson in his book, The Eighth Day of Creation (New York, 1979). Permission to quote must be obtained from Dr. Judson and access to some files is restricted.

The psychologist and behavioral geneticist Bronson Price made important contributions to the study of the genetics of mental traits in twins. Receiving his doctorate from Stanford in 1934, Price began down a research path that led him to study under Aleksandr R. Luria in Moscow from 1934-1935, and thereafter to the Department of Psychology at Ohio State. In 1941, Price changed course professionally, entering into war-time government service, never to return to academia, working first with the National Office of Vital Statistics and later as a statistician with the Children's Bureau and the Office of Education. The Price Papers contains one linear foot of correspondence relating to Bronson Price's interests in genetics and eugenics, with an emphasis upon Price's post-doctoral experiences in the Soviet Union and his long-term interests in the genetic study of twins. In addition to fairly extensive correspondence with H. J. Muller and Lewis Terman, the collection includes interesting materials relating to the Foundation for Germinal Choice, eugenic sterilization, and an extensive bibliographic card file used by Price in his research on twins post-1940. This note is currently under review for revision.

One of the seminal figures in the emergence of the Modern or Neo-Darwinian Synthesis during the mid-twentieth century, George Gaylord Simpson (1902-1984) helped define the unique contribution made by vertebrate paleontology to the life sciences. A specialist in Mesozoic and early Cenozoic mammals, Simpson's contributions to the fusion of Darwinian natural selection and Mendelian genetics were both empirical and theoretical, culminating in his major works Tempo and Mode in Evolution and The Meaning of Evolution. From his posts at the American Museum of Natural History (1927-1959), Columbia University (1945-1959), Harvard (1959-1967), and the University of Arizona (1967-1984), Simpson became one of the most influential paleontologists of the century, helped in part by his ability to write successfully for both a technical, professional audience and a popular audience. The Simpson Papers include a comprehensive assemblage of professional and personal correspondence, reflecting nealy all phases of Simpson's career. Written with charm, wit, and a sense of literary style, the correspondence touches on all aspects of modern paleontology, providing an important perspective on the emergence of contemporary evolutionary theory, biogeography, systematic theory and methodology, the relationship of science and religion, and creationism, as well as more general issues in scientific epistemology and social and political issues. The collection also includes autobiographical data and writings, lectures, class notes and papers, research data, material on his scientific expeditions (diaries in carbon form, photos, notes, etc.), publication material (he was author of some 800 publications), extensive photographic material, diplomas, and medals.
