Karl Landsteiner (German: [kaʁl ˈlantˌʃtaɪnɐ]; 14 June 1868 – 26 June 1943) was an Austrian biologist, physician, and immunologist. He 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 in 1937 identified, with Alexander S. Wiener, the Rhesus factor, thus enabling physicians to transfuse blood without endangering the patient's life. With Constantin Levaditi and Erwin Popper, he discovered the polio virus in 1909.
