Portrait of a pioneer

A portrait recently added to the walls of the School of Medicine honors Dorothy M. Horstmann, M.D., Sc.D., the John Rodman Paul Professor Emeritus of Epidemiology and Pediatrics. In 1961 she was the first woman named as a professor and eight years later was named to the endowed professorship. The portrait is a color photograph, taken by James C. Niederman, M.D., H.S. '50, clinical professor of epidemiology, that has been printed on linen rather than photographic paper. The framed portrait hangs near the Beaumont Room on the second floor of the Sterling Hall of Medicine. Dr. Horstmann came to Yale in 1942 as the Commonwealth Fund Fellow in preventive medicine. She worked with Dr. Paul, for whom her endowed chair was named. In 1944 she returned to the University of California at San Francisco, where she pursued her medical studies, and joined the Yale faculty in 1945. She played a major role in developing and evaluating vaccines for poliomyelitis and German measles.
