Quick Answer
Karl Landsteiner, with Alexander Wiener, identified the Rh factor in 1940. It became crucial for blood transfusion safety and pregnancy care.
The Full Story
Karl Landsteiner and Alexander Wiener described the Rh factor in 1940 after studying blood reactions in rhesus monkeys and humans. The Rh system, especially the D antigen, is now one of the most important blood group systems after ABO. Rh incompatibility can cause hemolytic disease of the newborn when an Rh-negative mother carries an Rh-positive fetus. Routine Rh testing and treatment have dramatically reduced these risks.
