poison gas canisters found by the Red Army at the end of World War II at
Auschwitz 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. ==Bibliography==
