Dr. Landsteiner's colleagues identify a fourth blood group (AB) that causes clumping in the red cells of both groups "A" and "B." -
Sodium Citrate Prevents Clotting
Researchers Albert Hustin and Luis Agote discover that adding sodium citrate to blood will prevent clotting. Dr. Hustin publishes his findings in April. -

Dr. Richard Lewisohn, formulates the optimum concentration of sodium citrate that can be mixed with donor blood to prevent curdling but poses no danger to the recipient. -
Blood can be stored
At the Rockefeller Institute, Francis Peyton Rous and J.R. Turner develop a citrate-glucose solution that allows blood to be stored for a few weeks and still be able to be used for transfusion. -
Establishing the first bloos depot
Dr. Oswald Robertson, collects and stores type O blood, with citrate-glucose for casualties in World War I. He establishes the first blood depot. -
Organized Donor Service
Percy Lane Oliver begins a blood donor service out of his home in London. He organizes his information so that the donnors can be contacted immediately when needed. -

Dr. Bernard Fantus introduces the term "blood bank" to describe the donation, collection, and preservation of blood. -
DIscovery of Uneeded Antibodies in Fetus
Drs. Philip Levine and R.E. Stetson discover an unknown antibody in the blood of a woman who has given birth to a stillborn. The doctors realize that Father's genetics can cause an uneeded production of an anti-body in the fetus. -
A Way to Seperate Plasma is Created
Edwin Cohn (biochemist) creates a way to separate out plasma's different proteins. By heating, cooling and mixing plasma with ethyl alcohol, they are able to isolate plasma. -
Increasing Blood Volume
Dr. Isidor Ravdin (surgeon) successfully treats victims of the Pearl Harbor attack with albumin; they are able to increase blood volume. -
Understanding Transfusion-transmitted hepatitis
Dr. Paul Beeson, in his report, links the occurrence of jaundice (a yellowish coloring of the skin) to blood/plasma transfusions the patients received earlier; this gives example of tranfusion-transmitted hepatitis. -
The American Association of Blood Banks
Independant blood banks across America join together and from the American Association of Blood Banks. -
Plastic Bags are Used for Storing Blood
Dr. Carl W. Walter (surgeon) develops an effective plastic bag for the collection of blood which replaces the use of glass bottles. This replacement is more durable and sanitary. -
Understanding Hemoglobin
Through the use of X-ray crystallography, Dr. Max Perutz is able to understand the structure of hemoglobin (the protein within red blood cells that carries oxygen). -
A Solution for Hemophiliacs
Dr. Judith Pool (physiologist) discovers that slowly thawed frozen plasma yields deposits high in Factor VIII (a factor that gives gives plasma a greater power to clog and make the patient stop bleeding). Hemophiliacs no longer have to travel to the hospital to be treated since it can be frozen and kept at thier home. -
An Even More Powerful Form of Plasma
Drs. Kenneth M. Brinkhous produces a highly concentrated form of Factor VIII. The result is 100 times stronger than raw plasma, and can be easily stored and injected into patients. -
Identifying Hepatitis B
Dr. Baruch Blumberg identifies a substance on the surface of the hepatitis B virus that triggers the production of antibodies. His work allows doctors to identify hepatitis B in patients. -
