Carl Peter Henrik Dam
The Danish biochemist Carl Peter Henrik Dam (1895-1976) shared the Nobel Prize in Physiology/Medicine for his discovery of vitamin K.Henrik Dam, the son of Emil Dam, an apothecary, was born in Copenhagen on Feb. 21, 1895. He graduated in chemistry at the Polytechnic Institute, Copenhagen, in 1920 and then held two instructor's posts in chemistry and biochemistry. In 1928 he was appointed assistant professor of biochemistry in the University of Copenhagen. In 1929 he was appointed associate professor, and in 1941 professor. In 1934 he graduated as a doctor of science of that university. While holding a Rockefeller Fellowship he worked at Freiburg (1932-1933) and at Zurich (1935).In 1928 Dam started to work on the cholesterol metabolism of chicks. He fed them a practically sterol-free artificial diet to which vitamins A and D had been added. He proved that, contrary to the current view, chicks could synthesize cholesterol.

He shared the Nobel Prize with Doisy in 1943.In 1937 Dam showed that the absence of vitamin E from the diet of chicks caused excessive exudation of plasma from the capillaries. He subsequently showed that the diet had also to be deficient in certain fatty acids. Much of his later work dealt with fatty acids, and he was for a period (1956-1963) director of the division of biochemistry of the Danish Fat Research Institute. He was also the president of the Danish Nutrition Society from 1967-1970.In addition to his Nobel Prize, Dam's many other honors included the Honorary Fellowship of the Royal Society of Edinburgh. He died on April 17, 1976. Further Reading A biography of Dam is in Nobel Lectures, Physiology or Medicine, 1942-1962 (1964), which also contains his Nobel Lecture. A discussion of his work is in Theodore Sourkes, Nobel Prize Winners in Medicine and Physiology, 1901-1965 (1966).
