Biography

Karl Landsteiner was an Austrian-Jewish American immunologist who discovered human blood groups.

How & why

Karl Landsteiner was born near Vienna to Jewish parents and later converted to Catholicism. In 1900–1901 he discovered that human blood comes in distinct groups — the ABO system — explaining why some transfusions succeeded while others were fatal, and making safe blood transfusion possible for the first time. He later co-discovered the Rh factor and the polio virus. For the blood-group work he received the 1930 Nobel Prize in Physiology or Medicine.
