Harro Schulze-Boysen, a great-nephew of Admiral Alfred von Tirpitz, was active in the Jungdeutscher Orden (a nationalist youth organization) at the end of the 1920s. As publisher of the journal â€śgegnerâ€ť (â€śopponentâ€ť), he had a wide variety of contacts in different political camps in 1932-33. After â€śgegnerâ€ť was banned he was briefly imprisoned in an SA torture cellar in Berlin. In May 1933 Schulze-Boysen began a training course at the commercial aviation school in WarnemĂĽnde. From April 1934 on he worked in the Reich Aviation Ministry. In the mid-1930s he gathered a circle of close friends around himself which developed into a resistance group. Its members included his wife Libertas, Elfriede Paul, Walter KĂĽchenmeister, Elisabeth and Kurt Schumacher, and others. Together with Arvid Harnack, First Lieutenant Schulze-Boysen in the AttachĂ© Group of the Reich Aviation Ministry was the leading figure in the Red Orchestra resistance organization. In the first six months of 1941, Harnack and Schulze-Boysen informed a Soviet embassy representative about the National Socialistsâ€™ plans for an attack on the Soviet Union. Schulze-Boysen was willing to maintain contact with Moscow during the war via a radio transmitter, but technical problems prevented the establishment of transmissions. After June 22, 1941 Schulze-Boysen recruited new members to the resistance, and was involved in writing leaflets and in a flyposting action. He had contacts to opponents of Hitler with various political and ideological viewpoints. At the end of October 1941, a courier from the Soviet military intelligence service arrived in Berlin from Brussels and visited Schulze-Boysen for a discussion. The Gestapo discovered Schulze-Boysenâ€™s name and address from a decoded telegram from Moscow to Brussels, and arrested him on August 31, 1942. He was sentenced to death by the Reich Court Martial on December 19, 1942. On Hitlerâ€™s orders he was murdered by hanging in Berlin-PlĂ¶tzensee.
