Physician, research scientist, teacher, public servant, Dr. Florence Sabin was all of these and much more. One of the first women accepted by Johns Hopkins School of Medicine, she graduated with honors in 1900 and interned there. The Baltimore Association for the Promotion of University Education for Women financed her research to find the origin of the lymphatic system. She went on to become a full professor of histology and the first woman professor at the medical school. She later moved to the Rockefeller Institute, where she developed a new tuberculosis treatment and made exciting discoveries about the human circulatory system. Retiring in Colorado, Dr. Sabin was summoned back to work by the governor to improve the state’s poor public health conditions. She got much needed legislation passed. Among the results: Denver’s tuberculosis death rate dropped from 54.7 to 27 persons per 100,000. She is one of two Colorado citizens whose likeness stands in the statuary hall of the U.S. Capitol.
