Butenandt commence ses études à l'université de Marburg puis à Göttingen où il prépare sous la direction d'Adolf Windaus un doctorat de chimie qu'il soutient en 1927. Son travail de thèse porte sur la structure chimique de la roténone, un produit naturel possédant des propriétés insecticides. Il devient assistant de Windaus et, en 1931, il est nommé directeur du laboratoire de chimie organique et de biochimie de l'Institut de chimie de Göttingen. Il est professeur de chimie organique à Dantzig de 1933 à 1936, puis directeur de l'Institut Kaiser-Wilhem à Berlin jusqu'en 1944. Directeur de l’Institut de biochimie de Tübingen de 1944 à 1956, puis de celui de Munich de 1956 à 1960, il est alors nommé à la direction de l'Institut Max-Planck, qui remplace depuis la fin de la guerre l'Institut Kaiser-Wilhem ; il occupe ce poste jusqu'en 1972.  Sur la suggestion de Windaus, Butenandt oriente ses […]

Adolf Friedrich Johann Butenandt Adolf Friedrich Johann Butenandt German biochemist who, with Leopold Ruzicka, was awarded the 1939 Nobel Prize for Chemistry for his work on sex hormones. Although forced by the Nazi government to refuse the prize, he was able to accept the honour in 1949. Butenandt studied at the universities of Marburg and Gottingen, receiving his Ph.D. from the latter in 1927. He then taught at Gottingen and at the Institute of Technology in Danzig (now Gdansk, Pol.). Butenandt was director of the Kaiser Wilhelm Institute (later the Max Planck Institute) for Biochemistry in Berlin beginning in 1936, and when the institute moved to Tubingen in 1945 he became a professor at the University of Tubingen. In 1956, when the institute relocated to Munich, Butenandt became a professor at the University of Munich. He also served as president of the Max Planck Society for the Advancement of Science from 1960 to 1972. In 1929, almost simultaneously with Edward A. Doisy in the United States, Butenandt isolated estrone, one of the hormones responsible for sexual development and function in females. In 1931 he isolated and identified androsterone, a male sex hormone, and in 1934, the hormone progesterone, which plays an important part in the female reproductive cycle. It was now clear that sex hormones are closely related to steroids, and after Ruzicka showed that cholesterol could be transformed into androsterone, he and Butenandt were able to synthesize both progesterone and the male hormone testosterone. Butenandt's investigations made possible the eventual synthesis of cortisone and other steroids and led to the development of birth control pills.
