Wolfram Sievers (10 July 1905 – 2 June 1948) was Reichsgeschäftsführer, or managing director, of the Ahnenerbe from 1935 to 1945.
Sievers was born in 1905 in Hildesheim in the Province of Hanover (now in Lower Saxony), the son of a Protestant church musician. It is reported that he was musically gifted, that he played the harpsichord, organ, and piano, and loved German baroque music. He was expelled from school for being active in the Deutschvölkischer Schutz und Trutzbund and went on to study history, philosophy, and religious studies at Stuttgart's Technical University while working as a salesman. A member of the Bündische Jugend, he became active in the Artamanen-Gesellschaft ("Artaman League"), a nationalist back-to-the-land movement.
Sievers joined the NSDAP in 1929. In 1933 he headed the Externsteine-Stiftung ("Externsteine Foundation"), which had been founded by Heinrich Himmler to study the Externsteine in the Teutoburger Wald. In 1935, having joined the SS that year, Sievers was appointed Reichsgeschäftsführer, or General Secretary, of the Ahnenerbe, by Himmler. He was the actual director of Ahnenerbe operations and was to rise to the rank of SS-Standartenführer by the end of the war.
In 1943 Sievers became director of the Institut für Wehrwissenschaftliche Zweckforschung (Institute for Military Scientific Research), which conducted extensive experiments using human subjects. He also assisted in assembling a collection of skulls and skeletons for August Hirt's study at the Reichsuniversität Straßburg as a part of which 112 Jewish prisoners were selected and killed, after being photographed and their anthropological measurements taken.
