Charles R. Drew

Charles Richard Drew (June 3, 1904 – April 1, 1950) was an American physician, surgeon, and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II. This allowed medics to save thousands of lives of the Allied forces. The research and development aspect of his blood storage work is disputed. As the most prominent African-American in the field, Drew protested against the practice of racial segregation in the donation of blood, as it lacked scientific foundation, and resigned his position with American Red Cross, which maintained the policy until 1950.
