Richard, 1900, 1967, dt. Biochemiker (Untersuchungen auf dem Gebiet der Vitamine u. Fermente); Nobelpreis 1938.
(1900-1967) Austrian-born German chemist who determined the structures of vitamins A, B2, and B6 in the 1930s, having isolated them from cow’s milk. He was awarded the 1938 Nobel Prize for Chemistry.
Kuhn was born in Vienna and educated there and at Munich, Germany. In 1929 he became professor at Heidelberg and director of the Kaiser Wilhelm (later Max Planck) Institute for Medical Research. He remained there until the late 1930s, when he was caught in a Nazi roundup of Jews and imprisoned in a concentration camp. He was unable to receive his Nobel Prize until the end of World War II in 1945, when he returned to work in Heidelberg.
Kuhn's early research concerned the carotenoids, the fat-soluble yellow pigments found in plants which are precursors of vitamin A.
In the 1940s, Kuhn continued to carry out research on carbohydrates, studying alkaloid glycosides such as those that occur in tomatoes, potatoes, and other plants of the genus Solanum. In 1952, he returned to experiments with milk, extracting carbohydrates from thousands of liters of milk using chromatography. This work led in the 1960s to the investigation of similar sugar-type substances in the human brain.
