Gerhard Domagk

Domagk, Gerhard (1895–1964), German pharmacologist who discovered the antibacterial action of the dye prontosil red, which led to the discovery of other sulfa drugs. In recognition of this, Domagk was offered the 1939 Nobel Prize for physiology or medicine, but the Nazi government did not allow him to accept it at the time. He received the Nobel Prize medal in 1947.
