'''Sir Hans Adolf Krebs''' (25 August 1900 – 22 November 1981)<ref>{{cite doi|10.1098/rsbm.1984.0013}}</ref><ref>{{cite doi|10.1016/S0065-2571(00)00026-1}}</ref><ref>{{cite doi|10.1080/152165400300001462}}</ref><ref>{{cite doi|10.1016/S0140-6736(05)75758-5}}</ref><ref>{{cite pmid| 2056924}}</ref> was a German [[physician]] and [[biochemist]]. Krebs is best known for his identification of two important metabolic cycles: the [[urea cycle]] and the [[citric acid cycle]]. The latter, the key sequence of metabolic chemical reactions that produces energy in cells, is also known as the ''Krebs cycle'' and earned him a [[Nobel Prize in Physiology or Medicine|Nobel Prize]] in 1953, which he shared with [[Fritz Lipmann]].

==Early years==
Krebs was born in [[Hildesheim]], [[Germany]], to Georg Krebs, an [[Otolaryngology|ear, nose, and throat]] [[surgery|surgeon]], and Alma Davidson. He went to school in Hildesheim and studied [[medicine]] at the [[University of Göttingen]] and at the [[University of Freiburg]] from 1918–1923. He earned his Ph.D. at the [[University of Hamburg]] in 1925, then studied [[chemistry]] in [[Berlin]] for one year, where he later became an assistant of [[Otto Heinrich Warburg|Otto Warburg]] at the [[Kaiser Wilhelm Institute for Biology]] until 1930.

==Career==
Krebs joined the German army in 1932, and was appointed to the 13th mechanized infantry division; until the Nazi party came to power in Germany Jews were welcome in the German army. Krebs returned to clinical medicine at the municipal hospital of [[Altona, Hamburg|Altona]] and then at the medical clinic of the [[University of Freiburg]], where he conducted research and discovered the [[urea cycle]]. Because he was Jewish, he was barred from practicing medicine in Germany and he emigrated to England in 1933. He was invited to [[Cambridge]], where he worked in the [[biochemistry]] department under [[Sir Frederick Gowland Hopkins]] (1861–1947). Krebs became professor of biochemistry at the [[University of Sheffield]] in 1945.
Krebs's area of interest was intermediary [[metabolism]]. He identified the [[urea cycle]] in 1932, and the [[citric acid cycle]] in 1937 at the University of Sheffield. He moved to Oxford as Professor of Biochemistry in 1954 and after his retirement continued work at the [[Radcliffe Infirmary]], Oxford until his death. He was a fellow of [[Trinity College, Oxford|Trinity College]].

In 1953 he received the [[Nobel Prize in Physiology or Medicine|Nobel Prize in Physiology]] for his "discovery of the citric acid cycle." He was knighted in 1958.

He was elected Honorary Fellow of [[Girton College]], [[Cambridge University]] in 1979.

==Personal life ==
Krebs was married in 1938 to Margaret Cicely Fieldhouse with whom he had three children: sons, [[John Krebs, Baron Krebs|John]] (later [[John Krebs, Baron Krebs|Baron Krebs]], an [[ornithologist]] and member of the [[House of Lords]]) and Paul, and daughter, Helen. Krebs died in [[Oxford]], [[England]] in 1981.
