Any person who has received a lifesaving blood transfusion owes a debt of gratitude to Dr. Charles Drew, an eminent surgeon, teacher, and scientist. In 1940, Dr. Drew devised the system to process and store large amounts of plasma, and that system is still used today. For his work in the blood plasma projects, Dr. Drew received the Spingarn Medal from the National Association for the Advancement of Colored People in 1944.
