Life

The son of a dentist grew up in Switzerland, studied chemistry at the University of Zurich and was at 1911 Alfred Werner with the work of the cobalt valence isomerization studies of doctorate . From 1912 to 1918 he worked on the synthesis of organic arsenic compounds in the laboratory of the physician Paul Ehrlich in Frankfurt am Main and returned to the University of Zurich in 1918 as an associate professor of organic chemistry. From 1919 until his retirement in 1956 he was Alfred Werner's successor as director of the Institute of Chemistry. In 1950/51 he was also rectorthe University. In Zurich, Karrer researched polysaccharides , which have been plant pigments since 1926. He isolated vitamins A (1931) and K (1939) and synthesized vitamins B 2 and E, among others . He also examined the constitution of the carotenoids and flavins . His “Textbook of Organic Chemistry” , published in 1927, has been published and translated many times. His fields of work later also included the investigation of therapeutically active substances, including above all curare alkaloids, which are used for anesthesiology . Karrer was a member of numerous scientific academies, such as the German Academy of Sciences Leopoldina since 1925 , the Royal Society of Edinburgh since 1943 , the National Academy of Sciences since 1945 and the Royal Society and the Académie des Sciences since 1947, as well as chemical and biochemical societies. He died in 1971 at the age of 82 and was buried in the Fluntern cemetery in Zurich .
