Wolfram Sievers ("the Nazi Bluebeard", July 10th 1905 - June 2nd 1948) was a German man who was the managing director of the Ahnenerbe, a thinktank set up by Nazi Party member Heinrich Himmler to fuel the systematic extermination of Jews and other groups deemed "sub-human". Specifically, Sievers was the director of a branch of the Ahnenerbe called the Institute for Military Scientific Research, which conducted unethical experiments on humans. As the highest administrative officer in the Ahnenerbe, he assisted in the mass murder of 112 Jewish prisoners, conducted so that the Nazis could use their skulls to demonstrate the alleged racial inferiority of the Jews. He was tried for crimes against humanity at the Nuremberg Doctor's Trial and executed by hanging on June 2nd, 1948 at Landsberg prison.
