In 1976, Dr. Rosalyn Yalow became the first woman to win the Albert Lasker Prize for Basic Medical Research. One year later, in 1977, she became the second woman ever to win a Nobel Prize in Medicine. Working at the Bronx Veterans Administration with Solomon A. Berson, she had developed radioimmunoassay (RIA), a system that enables scientists to detect minute traces of antigens, hormones, and drugs within blood and other fluids. In her oral history interview, Dr. Yalow discusses her experiences in a field that included few women and few Jews and managing her professional work and family life.
