Karl Landsteiner Karl Landsteiner Karl Landsteiner, , (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 identified, with Alexander S. Wiener, the Rhesus factor, in 1937, thus enabling physicians to transfuse blood without endangering the patient's life.

Albert Einstein's 1921 Nobel Prize Award mainly recognized his 1905 discovery of the mechanism of the photoelectric effect and "for his services to Theoretical Physics". The Nobel committee passed on several nominations for his many other seminal contributions, although these led to prizes for others who later
