Zyklon B Companies

Two German firms, Tesch/Stabenow and Degesch, produced Zyklon B gas after they acquired the patent from Farben. Tesch supplied two tons a month, and Degesch three quarters of a ton. The firms that produced the gas already had extensive experience in fumigation. "In short, this industry used very powerful gases to exterminate rodents and insects in enclosed spaces; that it should now have become involved in an operation to kill off Jews by the hundreds of thousands is not mere accident."(Hilberg, Commandant, 567) After the war the directors of the firms insisted that they had sold their products for fumigation purposes and did not know they were being used on humans. But the prosecutors found letters from Tesch not only offering to supply the gas crystals but also advising how to use the ventilating and heating equipment. Hoess testified that the Tesch directors could not help but know of the use for their product because they sold him enough to annihilate two million people. Two Tesch partners were sentenced to death in 1946 and hanged. The director of Degesch received five years in prison. (Feig)
