Edward Adelbert Doisy

Edward Adelbert Doisy , 1893-1986, American biochemist, b. Hume, Ill., grad. Univ. of Illinois (B.A., 1914), Ph.D. Harvard, 1920. For his discovery of the chemical nature of vitamin K he shared with Henrik Dam the 1943 Nobel Prize in Physiology or Medicine. Doisy and others synthesized vitamin K in 1939. He contributed to the knowledge of metabolism, insulin, and blood buffers and isolated the female sex hormones estrone (1929) and estradiol (1936). He taught biochemistry at Harvard (1915-17) and at the medical school of Washington Univ., St. Louis (1919-23), and was professor of biochemistry at the medical school of St. Louis Univ. (1923-65).

Doisy, Edward Adelbert (1893–1986) American biochemist; first isolated the oestrogens and independently isolated vitamin K, determined its structure and synthesized it; Nobel Prize 1943. See also Dam.
