In 1940, surgeon Charles Richard Drew published his Columbia University doctoral thesis, titled "Banked Blood: A Study in Blood Preservation." According to the Science History Institute, this milestone made Drew the first African American to earn a doctorate in medical science from Columbia. The work represented years of laboratory experimentation into fluid replacement and blood chemistry, establishing systematic methods for processing and storing blood components. Drew’s research arrived precisely as World War II began to devastate Europe, transforming a theoretical medical investigation into an urgent global logistics operation.
The Science of Fluid Replacement
Born in Washington, D.C., Drew attended Amherst College, where he was one of 13 African Americans in a student body of 600. After graduating, he earned his medical and surgical degrees from McGill University in Montreal in 1933. During his residency from 1933 to 1935, Drew developed a deep interest in blood transfusions. He joined the Howard University College of Medicine faculty in 1935 and received a Rockefeller fellowship in 1938 to pursue specialty surgical training at Columbia University and Presbyterian Hospital. Under physician John Scudder, Drew directed an experimental blood bank for seven months, conducting research into blood chemistry and liquid preservation.
Scaling Plasma for Wartime Crisis
When World War II created a desperate need for overseas trauma care, Drew became medical director of the Blood for Britain relief program. Using the Presbyterian Hospital blood bank as a model, Drew and Scudder focused on processing plasma rather than whole blood. Whole blood spoiled quickly and required strict type-matching. Plasma—the fluid left after removing red blood cells—treated shock effectively, proved easier to transport, resisted spoilage, and could be administered across all blood types. Drew implemented centrifuging and sedimentation techniques to extract and package plasma safely. By January 1941, the project collected over 14,000 blood donations and shipped 5,000 liters of plasma to England.
Bloodmobiles and Standardized Banking
Following the success of Blood for Britain, Drew led a three-month pilot program for the American Red Cross that served as the blueprint for the U.S. military’s National Blood Donor Service. During this initiative, he introduced the mass production of dried plasma, which simplified field storage and transport. To expand collection capacity, Drew pioneered mobile collection vehicles known as bloodmobiles. These self-contained units traveled directly to donors, establishing the template for modern community blood drives. After completing the pilot, Drew returned to Howard University in April 1941, taking charge of the surgery department to train future generations of Black surgeons.
Challenging Institutional Segregation
Despite his foundational technical contributions, Drew faced pervasive racial discrimination within medical institutions. Both the Blood for Britain project and the Red Cross pilot program enforced policies segregating blood donations by race, with the Red Cross initially excluding Black donors entirely. Drew publicly condemned these discriminatory policies, arguing that race had no biological relevance to blood plasma safety. He also petitioned professional medical organizations, including the American Medical Association, to admit Black physicians. For his achievements and civil rights advocacy, the NAACP awarded Drew its highest honor, the Spingarn Medal, in 1944.
Drew's foundational work in mass plasma extraction and mobile collection transformed emergency trauma care into a modern global medical system. By standardizing blood component separation and logistics, his methods established the structural blueprint for modern disaster response, battlefield medicine, and routine transfusion logistics that save countless lives worldwide today.
