Fritz Albert Lipmann (June 12, 1899 - July 24, 1986) was a German-American biochemist. In 1939, Lipmann immigrated to the United States, fleeing the Nazi regime. In 1945 he was co-discoverer of coenzyme A. Coenzyme A (CoA, CoASH, or HSCoA) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. For this, together with other research on coenzyme A, he was awarded half the Nobel Prize in Physiology or Medicine in 1953 (shared with Hans Adolf Krebs). From 1949 to 1957, he was appointed Professor of Biological Chemistry at Harvard Medical School. Afterward, he taught and researched at Rockefeller University in New York City. He died in 1986 at the age of 87.
