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.

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.
