Founded in 1931, the Genetics Society of America works to facilitate communication among scientists with an interest in research and education in genetics and cognate fields. The GSA Records provide information on the history of the Genetics Society of America from the time of its founding in 1931. Included is correspondence between various officers, members, and outside individuals and organizations, files on standing and ad hoc committees, Records concerning accounts and finances, membership data, files relating to annual meetings, local meetings, and international meetings, and information on special commissions or ad hoc groups of the Society. Among the more noteworthy files are those for the Committee on Genetics, Race, and Intelligence, 1974-1975. This note is currently under review for revision.

This miscellaneous collection relates to numerous topics in genetics: cattle breeding (especially the American Jersey Cattle Club), longevity, radiation, International Congress of Genetics (the 10th, 11th, and 13th), Gregor Mendel, aid for refugee scientists, and the records of the Genetics Society of America (1947-1974). The photographs series accession # 1968 433pr, was added to the finding aid in 2016.

Mostly concerned with Blakeslee's studies on beans, blood groups, colchicine, Datura, embryo cultures, and horticulture.

Other letters are about the Carnegie Institution of Washington, "Biological Abstracts," American Association for the Advancement of Science, American Philosophical Society, Institut de France, University of Connecticut. Also contains travel letters from Germany and miscellaneous lectures.

Ernst Wolfgang Caspari was an important contributor to behavior and developmental genetics, working primarily on the mealmoth Ephestia. Trained in Alfred Kuhn's laboratory at the University of Göttingen (1933-1935), Caspari was forced from his position by the Nazis in 1933, escaping to the United States five years later. As a professor of biology at Lafayette College, Wesleyan University, and the University of Rochester, Caspari continued his research on Ephestia, mouse genetics, and behavior genetics until his retirement in 1975. The Caspari Papers includes correspondence, papers, grant reports, and lectures relating to Caspari's genetic research dating primarily from the period after his departure from Germany. In addition to substantial material on behavior genetics and human evolution, the collection includes correspondence relating to Caspari's editorial work for Advances in Genetics, and his involvement with the American Institute of Biological Sciences, the Center for Advanced Study in the Behavioral Sciences, Cold Spring Harbor Laboratory, Fifth Banff Conference on Theoretical Psychology, Genetics Society of America, International Conference on the Unity of Science, Social Science Research Council, Committee on Genetics and Behavior, and the U.S. Atomic Energy Commission.

Sewall Wright ranks among the most influential figures in the field of population genetics during the 20th century, and made important contributions to biostatistics, biometrics, and evolutionary theory. These papers contain much of Wright's professional correspondence, scattered research notes, and drafts of a small number of papers.

Founded by the Brooklyn Institute of Arts and Sciences in 1890, the Biological Laboratory at Cold Spring Harbor, N.Y., was little more than a languishing outpost until the arrival of Charles B. Davenport in 1898. Over the course of two decades, the ambitious young biologist used his extraordinary administrative skills to transform the institution into the premier center of eugenical study and, as its director, to position himself as the leading spokesman for eugenical research in North America. The Davenport Papers (ca. 63 lin. feet) is a large and nearly comprehensive body of correspondence, lectures, diaries (1878-1942, mostly brief entries of an uneven character), student notebooks and family correspondence pertaining to Charles Davenport and the Cold Spring Harbor Laboratory. The collection is divided into two series, the Charles Davenport Papers, which provides valuable documentation of the development of American biology, animal and plant genetics, and eugenics during the period 1898-1942, with some perspective on the international eugenics movement. Series II, the Cold Spring Harbor Records (ca.20 lin. feet), consists largely of administrative correspondence relating to the laboratory, including Davenport's correspondence with Carnegie administrators (esp. Robert Woodward and John Merriam), accounts and reports concerning financial matters, publications, salaries, material relative to the early history of Cold Spring Harbor labs, and records relative to the numerous professional assistants who worked under Davenport. Among the major correspondents are the American Breeders Association, Committee on Eugenics; American Eugenics Society; American Society of Naturalists; Committee on a Study of the American Negro; Galton Society (see also the extensive correspondence with William K. Gregory); Eugenics Education Society (see Mrs. S. Gotto correspondence); International Congresses of Eugenics; International Federation of Eugenic Organizations, Committee on Race Crossing; National Committee on Mental Hygiene; National Committee on Prisons and Prison Labor; and the Pan-American Conference on Eugenics and Homiculture. There are correspondence and papers relating to the Station for Experimental Evolution, the Eugenics Record Office, and the Carnegie Institution of Washington, and a substantial series relating to a long-range study of children carried out at Letchworth Village, Thiles, New York. 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.

The Papers of Curt Stern include extensive correspondence, lectures (1920s-1970s, 1.5 boxes), autobiographical material, articles, zoological course notes, photographs, etc. Stern's various areas of scientific interest are documented in the collection: the chromosome theory of heredity, role of gene mutation and chromosome rearrangements in evolution, action and interaction of genes during individual development, and particularly his contribution to the development of human genetics as a discipline (centered on his popular and influential book, Principles of Human Genetics, 1949, 1960, 1973). Both his career in Germany and the United States is documented in his correspondence. After studying with T. H. Morgan at Columbia University on a Rockefeller Foundation Fellowship (1924-1926), Stern returned to Richard Goldschmidt's lab at the Kaiser-Wilhelm Institute (1926-1932). There is material of note in the collection concerning this period when Stern helped to establish the cytological basis of crossing over. After a short stay at the California Institute of Technology in 1932, Stern's temporary residence in the U. S. became permanent, and his later career at the University of Rochester, 1933-1947 (Chairman, Department of Zoology) and at the University of California, Berkeley, 1947-1970 (there is abundant material on the Department of Zoology) is covered in the collection. There is other material on: American Association for the Advancement of Science Inter-Society Committee on Science Foundation Legislation, 1946-1947; American Society of Human Genetics (Pres., 1957); Atomic Energy Commission (Advisory Committee for Biology and Medicine, 1950-1955); Genetics (journal); Oak Ridge National Laboratory (Advisory Committee for Biology, 1955-1968); and the Rockefeller Foundation. Stern's correspondence with friends and colleagues in Germany, England, and the U. S., during the 1920s-1930s, is of particular note as it documents not only the developments in genetics and the institutional and administrative networks supporting research, but it also offers general comments and observations on science, Germany, and politics. The photographs (2 boxes) include pictures of many prominent geneticists and scientists.
