Dr. Charles Richard Drew
(1904–1950)

While researching blood transfusions at McGill University in Montreal and later at Columbia University in New York, Charles Drew realized that blood, like other liquids, could be preserved. His method, now known as blood banking, revolutionized medicine and changed the way doctors could work in remote areas or during times of war. Dr. Drew went on to form the Red Cross Blood Bank. Ironically, he died in a car crash after losing too much blood.
