Florence Rena Sabin (1871-1953)

• The Florence R. Sabin Papers
• Biographical Information
  • "Sabin stayed on the faculty at Johns Hopkins until 1925, and during that time distinguished herself both as a researcher and a teacher. She did important work on the origins of the lymphatic system, demonstrating (by injecting colored substances into the lymphatic channels) that its structures were formed from the embryo's veins rather than from other tissues, as other researchers believed. She also investigated the origins of blood vessels, blood cells, and connective tissue. To do this, she perfected the technique of supravital staining, which allowed the study of the living cells. In 1924, she became the first woman president of the American Association of Anatomists, and the next year, the first woman elected to membership in the National Academy of Sciences."
