Another important breakthrough came in 1937–40 when Karl Landsteiner (1868-1943), Alex Wiener, Philip Levine, and R.E. Stetson discovered the Rhesus blood group system, which was found to be the cause of the majority of transfusion reactions up to that time. Three years later, the introduction by J.F. Loutit and Patrick L. Mollison of acid–citrate–dextrose (ACD) solution, which reduced the volume of anticoagulant, permitted transfusions of greater volumes of blood and allowed longer-term storage.

In 1901, Karl Landsteiner discovered three human blood groups (O, A, and B), which made blood transfusions safer than they were prior to this . discovery. Another event that made blood transfusions even safer was in 1937–40 when Karl Landstiner, Alex Wiener, Philip Levine, and R.E. Stetson discovered the Rhesus blood group system, which was found to be the cause of the majority of transfusion reactions.
