A long-time member of the faculty at Johns Hopkins, the biochemist William Mansfield Clark made significant contributions to the understanding of oxidation-reduction potentials of organic systems. This collection of Clark's professional papers includes drafts of manuscripts and correspondence, especially with James B. Conant and Barnett Cohen, relating to Clark's life and research. Of particular note are Clark's Cutter lectures at Harvard in 1930 and his correspondence with Eric G. Ball, when Ball worked in Otto Warburg's lab in Berlin in 1937-1938. Clark's participation in professional organizations is reflected in correspondence with the Society of American Bacteriologists and with the Journal of Biological Chemistry, as well as with colleagues Stanley Benedict and Rudolph Anderson. There is some material relating to Clark's lectures and papers, and there are four student notebooks (physical chemistry, optics, thermodynamics/physics), and twenty-three miscellaneous scientific notebooks, 1941-1953.

This program is a luncheon address given by George Washington Corner at the 8th Annual Conference of The Society for the Scientific Study of Sex, held at the Barbizon Plaza Hotel, New York City, November 6, 1965.

This collection includes correspondence, research data, reviews of grant proposals, organizations participated in, laboratories worked for, and student recommendations. The correspondence in the collection dates primarily to the 1960s-70s, when Mildred Cohn worked at the University of Pennsylvania and at the Institute for Cancer Research in Philadelphia, later renamed, Fox Chase Cancer Center. The letters are professional in content, discussing biochemistry, molecular biology, nuclear magnetic resonance (NMR) experiments. The letters also concern lectures and participation in conferences and symposia, and there are materials relating to recommendations for students and colleagues for positions and promotions. Dr. Cohn's interest and involvement in the issue of women in science is presented, of particular note, her work with the University of Pennsylvania's Gender Equity Committee. The notebooks, by Cohn, her colleagues and students, contain extensive experimental data.

The Corner collection includes correspondence, biographical and research data, lectures, publications, notebooks and drawings, and also photographs. He was both a scientist, specializing in mammalian reproduction and the female reproduction cycle (being a co-discoverer of the hormone progesterone along with Willard M. Allen), and a medical historian writing both biography and institutional history.

Correspondence, notebooks, research data related to Cole's career as the first director at the Hospital of the Rockefeller Institute of Medical Research, 1908-1937. His research of pneumonia was conducted when the disease was epidemic. Personal correspondence reflect Cole's life as a medical resident at Johns Hopkins, 1899-1908. Documented are his memberships in leading medical organizations throughout his career, including the Association of American Physicians and the New York Academy of Medicine. This collection showcases the evolving changes in the medical profession from practicing physician to clinician.
