Hans Krebs

25 August 1900 – 22 November 1981

Sir Hans Adolf Krebs was a German-born British biochemist who discovered two fundamental metabolic pathways: the ornithine (urea) cycle and the citric acid cycle, the latter now known as the Krebs cycle. He shared the 1953 Nobel Prize in Physiology or Medicine for identifying the citric acid cycle. Forced to leave Nazi Germany, he built his career in Britain at Sheffield and Oxford.
