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).

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.

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.
