Sievers was tried during the
Doctors' Trial at Nuremberg after World War II, where he was dubbed "the Nazi Bluebeard" by journalist
William L. Shirer because of his "thick, ink-black beard". The Institute for Military Scientific Research had been set up as part of the Ahnenerbe, and the prosecution at Nuremberg laid the responsibility for the
experiments on humans which had been conducted under its auspices on the Ahnenerbe. Sievers, as its highest administrative officer, was accused of actively aiding and promoting the criminal experiments. Sievers was charged with being a member of an organization declared criminal by the International Military Tribunal (the SS), and was implicated in the commission of war crimes and crimes against humanity. In his defense, he alleged that as early as 1933, he had been a member of an anti-Nazi resistance movement which planned to assassinate Hitler and Himmler, and that he had obtained his appointment as Manager of the Ahnenerbe so as to get close to Himmler and observe his movements. He further claimed that he remained in the post on the advice of his resistance leader to gather vital information which would assist in the overthrow of the Nazi regime. Sievers was sentenced to death on 20 August 1947 in the
Doctors' Trial, and
hanged on 2 June 1948, at
Landsberg Prison in Bavaria. ==Influence==
