First Blood Bank Opens: Chicago Saves Lives with Stored Blood

Dr. Bernard Fantus established the world's first hospital blood bank at Cook County Hospital in Chicago on March 15, 1937, creating a system that transformed blood from a perishable emergency resource into a storable medical commodity. Fantus coined the term "blood bank" itself, drawing an analogy to a financial institution where deposits could be made in advance and withdrawals made when needed. Before Fantus's innovation, blood transfusion required a direct donor-to-patient transfer performed simultaneously in the operating room. Finding a compatible donor on short notice was often impossible, and patients frequently died from hemorrhage or surgical shock while doctors scrambled to locate a match. The discovery that sodium citrate could prevent blood from clotting and that refrigeration could preserve it for several days had been established during World War I, but no hospital had created a systematic storage and distribution system. Fantus, a Hungarian-born physician who had joined Cook County Hospital's staff in 1912, designed a system where donors could give blood in advance, which would be typed, tested, refrigerated, and cataloged for later use. Donors received credit for their contributions, which they or their family members could draw upon if they later needed transfusions. The system addressed both the supply problem and the timing problem that made emergency transfusions so unreliable. Cook County Hospital's blood bank proved so successful that hospitals across the country began establishing their own within months. The American Association of Blood Banks was founded in 1947 to standardize practices. The Red Cross launched its national blood collection program during World War II, building directly on the organizational model Fantus had created. Modern blood banking saves an estimated 4.5 million American lives per year. The entire global infrastructure of blood collection, storage, testing, and distribution traces its origin to a single refrigerator in a Chicago public hospital.
