Florence Rena Sabin (November 9, 1871 – October 3, 1953) was an American physician and medical scientist known for pioneering work on the development of the lymphatic system and for later transforming public health in Colorado. She was the first woman to hold a full professorship at the Johns Hopkins School of Medicine, the first woman elected to the National Academy of Sciences, and the first woman to head a department at the Rockefeller Institute for Medical Research. During retirement she led a public-health reform campaign in Colorado that produced the “Sabin Health Laws”; in 1951 she received the Albert Lasker Public Service Award for her public-health work.
