Karl Landsteiner in 1901, described blood types A, B and O, fist shooing the differences due to distinctive antigens carried by red blood cells. That by matching antigen types between donor and recipient could ensure a better transfusion. He also created the Blood alphabet groups, in 1902 he found AB type, in 1927 finessing a rare type of M and N

The ABO blood group system is widely credited to have been discovered by the Austrian scientist Karl Landsteiner, who identified the O, A, and B blood types in 1900.

Karl Landsteiner, ForMemRS (June 14, 1868 – June 26, 1943), was an Austrian biologist and physician. He is noted for having distinguished the main blood groups in 1900, having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and having identified, with Alexander S. Wiener, the Rhesus factor, in 1937, thus enabling physicians to transfuse blood without endangering the patient’s life.

Do you know your blood type? Blood typing is necessary for safe blood transfusions, where donor blood is given to a patient in need. If the recipient gets blood that’s not compatible with theirs, it can cause a transfusion reaction, which can cause serious symptoms or even death.

Experiments with blood transfusions, the transfer of blood or blood components into a person’s blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer.
