Adolf Butenandt was born in Germany on March 24, 1903 and died on January 18, 1995. He won the Nobel Prize in chemistry in 1939. The following linked item indicates his accomplishments:
"In 1929 he isolated oestrone in pure, crystalline form, almost at the same time that E.A. Doisy did this in America. In 1931 he isolated androsterone in pure, crystalline form. From androsterone he as well as Ruzicka, independently of each other, obtained testosterone in 1939, a compound which had been obtained from the testes in 1935 by Ernst Laqueur. Progesterone was isolated by Butenandt from the corpus luteum in 1934."
