Doisy, Edward Adelbert, 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).

Edward Adelbert Doisy (November 3, 1893October 23, 1986) was an American biochemist. He received the Nobel Prize in Physiology or Medicine in 1943 with Henrik Dam for their discovery of vitamin K and its chemical structure.

Doisy was born at Hume, Illinois, on November 3, 1893. He completed his A.B. degree in 1914 and his M.S. degree in 1916 from the University of Illinois at Urbana-Champaign. He completed his Ph.D. in 1920 from Harvard University.

For many years Doisy was a professor at Saint Louis University and has many remembrances at that school's medical campus.

He also competed with Adolf Butenandt at the discovery of estronein 1930. They discovered the substance independently but Butenandt was awarded with the Nobel Prize in Chemistry in 1939.
