Who discovered blood types?
Answers: The ABO blood group system is widely credited to have be discovered by the Austrian scientist Karl Landsteiner, who found three different blood types in 1900 he be awarded the Nobel Prize in Physiology or Medicine contained by 1930 for his work. Due to inadequate communication at the time it be subsequently found that Czech serologist Jan Jansk'y had independently pioneered the classification of human blood into four groups but Landsteiner's independent discovery have been agreed by the scientific world while Jansk'y remained contained by relative obscurity. Jansk'y's classification is however still used in Russia and states of former USSR . In America Moss published his own work within 1910.
The Rhesus system is named after the Rhesus Macaque, following experiments by Karl Landsteiner and Alexander S. Wiener, which showed that rabbits, when immunize with rhesus monkey red cell, produce an antibody that also agglutinates the red blood cells of masses humans. Landsteiner and Alexander S. Wiener discovered this factor in 1937 (publishing surrounded by 1940). The significance of the Rh factor was soon realize. Dr. Phillip Levine working at the Newark Beth Israel Hospital made a connection between the Rh factor and the incidence of erythroblastosis fetalis, and Wiener realize adverse reactions from transfusions be also resulting from the Rh factor. Wiener then pioneered the exchange transfusion to combat erythroblastosis fetalis within newborn infants. This transfusion technique saved the lives of oodles thousands of infants before intrauterine transfusion be invented which enabled much more severely affected fetuses to be successfully treated. Drs. Neva Abelson and L.K. Diamond co-discovered a simple experiment for the Rh factor which was widely applied.
Karl Landsteiner discovered the ABO system (Nobel price 1930) (and subsequently rhesus too 1937) - he recieved a Lasker award for this in 1946
