These letters concern William E. Castle's genetics' "law" of 1903. There are letters with Castle, L. C. Dunn, Clyde Keeler, J. A. Weir, Sewall Wright, and Conway Zirkle.

Thesis (PhD, The Hebrew University), 1993.

Includes correspondence, autobiographical notes, addresses, articles, and drawings. The collection reflects Riddle's interests in breeding, heredity, and evolution. He was interested in humanism and the presentation of biological and evolutionary theories. There is much information on Riddle's activities in favor of freedom of scientific teaching, especially in high schools.

Pamela Mack received her doctorate in the History and Sociology of Science at the University of Pennsylvania in 1983. She is currently a member of the Department of History at Clemson University. Mack's essay, "The Early Years of the Cold Spring Harbor Station for Experimental Evolution," was written for a class taught by Daniel Kevles in 1979. In it, she charts the origins and first decade of the Station for Experimental Evolution (1904 to 1914) and its transformation under the leadership of Charles B. Davenport into an institution devoted to the study of eugenics.

This collection consists of materials relating to Shull's work commissioned by the Carnegie Institution of Washington to collaborate with their grantee, Luther Burbank, with the aim of analyzing Burbank's data on plant breeding and hybridization and preparing it for publication in suitable scientific journals. Shull visited Burbank's plant-breeding farm in California eight times between 1906 and 1910. There are files for each plant genus involved in Burbank's work. These files contain notes, calculations, clippings from newspapers or periodicals, and an unpublished manuscript of Shull's final report to the Carnegie Institution. There is also a report by Edwin C. MacDowell, which gives background information about the collection.

In 1929, the geneticist C. C. Little founded the Roscoe B. Jackson Memorial Laboratory in Bar Harbor, Maine, a major center for the study of mammalian genetics, cancer, and related areas in basic biomedical research. An independent institution, the Lab has maintained a consistent scientific reputation both as a supplier of inbred strains of mice for genetic and biomedical research and for the scientific achievements of its researchers. Conducted by Susan Mehrtens in 1986, the Oral History Collection includes transcripts of extensive interviews with fifty scientists, administrators, and staff members of the Jackson Laboratory. At greater or lesser length depending on the subject, the interviews provide a detailed picture of the operations and administration at the laboratory, the culture of research, the sometimes contentious staff relations, and the research itself.

This collection includes correspondence, manuscripts (lectures and articles), research grant material, research data, and participation in organizations, such as, the American Society of Naturalists (President, 1968), Genetics Society of America (President, 1963), and the National Research Council. Of particular note, are the detailed data related to Drosophila eye pigment, and human chromosomes.

This collection contains some letters, but mostly there are copies of manuscripts by Kaufmann and others, concerning genetics in medical schools, and chromosone changes produced by drugs.

This collection includes documents (correspondence, drafts of talks, personal data sheets, and transcripts) relating to the Conference on Evolutionary Synthesis, which met in Boston in May and October 1974, and was sponsored by the American Academy of Arts and Sciences. There is background material on the organization of the conference, as well as correspondence, especially with William B. Provine, on the editing and publication of the proceedings (Mayr and Provine, eds., "The Evolutionary Synthesis..." 1980).

The principal letters in this collection are to Otto L. Mohr and concern problems and progress in genetics, the Nobel Prize, and some account of Mohr and his family under the Nazi occupation of Norway, 1940-1945. Included with this group is a partial biographical essay on Calvin Blackman Bridges.

The correspondence in this collection concerns behavior genetics, evolution, heredity, etc. There is material relating to the congresses of the Permanent International Committee on Genetics, and the IXth (Bellagio, 1953), Xth (Montreal, 1958), and XIth (The Hague, 1963) International Congress of Genetics. There is also correspondence pertaining to the Cold Spring Harbor Symposium on Quantitative Biology (1955), the Mendel Semi-Centennial Symposium (1950), the Soviet geneticists' visit to the U.S. in 1967, and to Anton R. Zhebrak.

The collection includes three accessions: (1) a portion of Lewontin's correspondence files (mainly A-L) and copies of papers acquired in 1979; (2) a 2003 accession with files on various subjects and correspondence with about 30 colleagues, and (3) a substantial 2018 accession of about 60 linear feet that includes correspondence, manuscripts, and subject files. The topics discussed in the letters are numerous, including much on contemporary scientific controversies such as race, Darwin, evolution, intelligence, and biological determinism.

This is a diverse collection, including correspondence, drafts of letters, notes and notebooks (on biometric methods; tables and formulae; science, nature and method; coefficient and correlation; vitalism; Japanese language); commonplace book (1924); autobiography; and over one hundred folders of unpublished writings. The correspondence and other material covers a variety of topics, including biology, eugenics, evolution and natural selection, human heredity, paramecia, protozoa genetics, U.S. immigration policy. There is much on the Seventh International Congress of Zoology (1907); letters to his father and wives, and from students and colleagues on his seventy-fifth birthday, 1943 (1 v.); diplomas and certificates of membership; and photographs.

The Austrian biologist Paul Kammerer was an outspoken proponent of the theory of inheritance of acquired characteristics (Lamarckism) during the time in which Mendelian theory was becoming deeply entrenched in biology. His major research efforts, straddling the First World War, centered on experiments performed on salamanders and on the midwife toad, and seemed to provide empirical support for a Lamarckian mechanism in evolution. He also developed a monistic "law of seriality," in which he attempted to explain coincidence as the product of a higher order natural law. A Socialist, Kammerer was widely regarded as a brilliant scientist, but for scientific, personal, and political reasons, he engendered as much antagonism as support, preventing him from ever obtaining a regular university appointment. His career ended tragically in allegations of fraud, followed by his suicide. The Kammerer Papers is comprised of photocopies of materials that document the brief, but controversial career of a non-Darwinian evolutionary biologist. The bulk of the collection consists of photocopies of articles by Kammerer, often from obscure newspapers or periodicals, along with a small number of letters to his friend Hugo Iltis, the geneticist and biographer of Mendel. Nearly all of these pertain to the Kammerer's experiments with amphibians to test Lamarckian inheritance or to his other biological theories. The collection also includes a small number of items dating from after Kammerer's death, but relating to his life and work, including two letters from his former supervisor Hans Przibram, a letter from Hugh Iltis (Hugo's son) to Arthur Koestler and the reply, and a brief biographical reminiscence of Kammerer written by Hugo Iltis.

In 1910, the Eugenics Record Office was founded in Cold Spring Harbor, New York, as a center for the study of human heredity and a repository for genetic data on human traits. It merged with the Station for Experimental Evolution in 1920 to become the Department of Genetics at the Carnegie Institution, and under the direction of Charles B. Davenport and later of Albert Blakeslee and Milislav Demerec, it became the most important center for eugenic research in the nation. However with intellectual currents shifting, the Carnegie Institution stopped funding the office in 1939. It remained active until 1944, when its records were transferred to the Charles Fremont Dight Institute for the Promotion of Human Genetics at the University of Minnesota. When the Dight closed in 1991, the genealogical material was filmed by the Genealogical Society of Utah and given to the Center for Human Genetics; the non-genealogical material was not filmed and was given to the American Philosophical Society Library. Following the original order, the ERO Records are organized into thirteen series: I. Trait Files, 1670-1964 ; II. Trait Card Boxes, 1904-1939 ; III. Family Traits Card Boxes, 1920-1939 ; IV. RFT Submitters Card Catalog, 1910s-1930s ; V. Record of Family Traits, 1911-1940 ; VI. Fitter Family Studies, 1913-1936 ; VII. Field Worker Files, 1911-1926 ; VIII. Volunteer Collaborators, 1912-1939 ; IX. Pedigrees, 1828-1926 ; X. Harry H. Laughlin Files, 1915-1938 ; XI. Bibliographia Eugenica, 1734-1934 ; XII. Midget Schedules, 1919-1964 ; XIII. Index Card Boxes, 1910s-1930s.

Though the Miscellaneous Manuscripts collection is composed of items that do not fall readily into any other existing collection, the two dominant intellectual areas represented in the collection are Early American History and History of Science.

This collection of correspondence, reports, and manuscripts concerns Stalker's research in genetics and evolutionary biology, particularly the evolutionary genetics of Drosophila. Most of the letters are scientific, although the usual academic politics in various departments is mentioned. There is also material on the Society for the Study of Evolution (1970).

In 1912, the University of California, Berkeley, became the first university in the nation to form a separate Department of Genetics. The first two appointments in the department went to plant geneticists Ernest Brown Babcock and Roy E. Clausen, and as the department grew slowly, shifting slightly away from its roots in agricultural science, it gained a strong reputation as an important center for research in several areas in genetics and evolutionary biology. The U.C. Berkeley Department of Genetics Collection contains a selective sampling of correspondence relating to the organization and early history of the nation's first Department of Genetics. Centered in the years 1912-1930, the collection consists primarily of correspondence to and from Babcock and Clausen, pertaining to their research, administrative matters, and the genetical community. Prominent among their correspondents are George H. Shull, Thomas Hunt Morgan, A. H. Sturtevant, and H. J. Muller.

The historian of science Robert C. Olby is a graduate of University College London and Oxford. Best known for his work on the history of genetics, especially the Bateson school, and for his study of the early history of molecular biology, Olby is currently a Research Professor in the History and Philosophy of Science at the University of Pittsburgh. He is the author of The Origins of Mendelism (1966), Charles Darwin (1967), The Path to the Double Helix (1974), and the Norton History of Biology. His current research is focused on the conceptual foundations of modern sensory neurophysiology and an intellectual biography of Francis Crick. The Olby Collection contains about 150 photocopies of correspondence and documents collected by Olby during research for The Path to the Double Helix. Among these is a copy of a manuscript by F. C. Crick and James D. Watson, "The Complementary Structure of Deoxyribonucleic Acid," prepared while Watson was at CalTech.

One of the most important natural historians in nineteenth century Britain, Charles Darwin provided the first compelling mechanism to account for organismal evolutionary change. Although lacking a coherent model of heredity, Darwin's natural selection has exerted an enormous influence over the biological sciences and since the introduction of Mendelian genetics, had remained the key unifying principle in the discipline. The APS Darwin Papers are a large a valuable assemblage of Darwin's correspondence with scientific colleagues, including Charles Lyell and George J. Romanes. They are included in the print version of the Correspondence of Charles Darwin (Cambridge Univ. Press).
