This represents some of his early pioneering work on the effect of x-rays on the development of embryos.

Alexander Hollaender was a leading researcher on the genetic effects of radiation. Born in Samter, Germany, in 1898 and arriving in the United States in 1921, Hollaender was educated at the University of Wisconsin, receiving his AB, MA, and Ph.D. there. He served on the faculty at the University of Tennessee and the University of Tennessee-Oak Ridge Graduate School of Biomedical Sciences. He was director of the division of biology at the Atomic Energy Commission's Oak Ridge National laboratory from 1946 until 1966. The 4 linear feet of the Alexander Hollaender Papers contain incoming and outgoing correspondence and reports relating to the genetic effects of radiation, specifically atomic radiation. Also included are documents of the International Conference on the Peaceful Uses of Atomic Energy; the NAS Committee on the Biological Effects of Atomic Energy, Genetics Panel; the United Nations Scientific Committee on Atomic Radiation; and the World Health Organization all of which Hollaender was closely involved with.

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.

A pathologist and cancer specialist, James B. Murphy (1884-1950) spent most of career associated with the Rockefeller Institute (1911-1950) investigating the role of lymphocytes in tuberculosis, x-ray mutagenesis, and the nature of malignant tumors in fowls. The Murphy Papers contains professional correspondence and research notes relating to James B. Murphy's cancer research at the Rockefeller, and information on several of the organizations to which he contributed or belonged, including the American Association for Cancer Research; American Bureau for Medical Aid to China; American Cancer Society; Bar Harbor Medical and Surgical Hospital; Roscoe B. Jackson Memorial Laboratory; Memorial Hospital for the Treatment of Cancer (New York City, ca. 1932-1950); National Advisory Cancer Council; and the New York Academy of Medicine (1923-1950). Murphy helped to develop mobile laboratories for hospitals in France during World War I.

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.

Thomas F. Anderson (1911-1991) was a biophysicist and electron microscopist whose research included Raman spectroscopy; the physiology of yeast; the biological effects of radiation; the biological applications of electron microscopy; and the genetics of bacteria, bacterial viruses, and bacteriophage. He was a Professor of Biophysics at the University of Pennsylvania and a Senior Member of the Institute for Cancer Research in Fox Chase.
