About Karl Weinbacher
Lived 1898 – 1946 (aged 47). Karl Weinbacher was a German manager and holocaust perpetrator.
Karl Weinbacher (23 June 1898 – 16 May 1946) was a German manager and war criminal who was executed after conviction by a British war tribunal following World War II. He and his boss, Bruno Tesch, were the only businessmen to be executed for their roles in Nazi atrocities and the Holocaust in Western Europe.
Life
Weinbacher worked at Degesch (Deutsche Gesellschaft für Schädlingsbekämpfung, which translates as German Corporation for Pest Control) until 1924, and then at Tesch & Stabenow (Testa, for short), where he received the position of manager in 1927, and by 1943 was director and deputy executive under owner and chief executive officer Bruno Tesch. Testa manufactured and sold Zyklon B, which was used not only for pest control and disinfestation, but also in the Holocaust in the gas chambers of Auschwitz to murder people. Weinbacher received a commission on all of the company's profits, including the Zyklon B sales.
After the end of World War II, Weinbacher, Tesch and Joachim Drosihn, the firm's first gassing technician, were arrested on 3 September 1945. They were tried by a British military tribunal at the Curiohaus trials in Hamburg from 1–8 March 1946, also called the Testa trial or the Zyklon B trial. In the cases of Weinbacher and Tesch, the court ruled that the prosecution had proven that both of them knew how the SS would use Zyklon B. Tesch and Weinbacher were convicted, while Drosihn was acquitted.
Tesch and Weinbacher were executed in Hamelin Prison on 16 May 1946.
