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.
