1941 February 6, The IG FARBENINDUSTRIE CHEMICAL CONCERN (Poland)
Decided to build a synthetic rubber plant in Auschwitz. The decision had been between locations in Norway or Auschwitz. They chose the latter due to better tax incentives. Tens of thousands of prisoners died working in the plant. Manpower turnover was 300%. Other major corporations like Siemens and Krupp also used Jewish slave labor to increase profits. The director of the plant, Dr. Walter Durrfeld was reelected to their Board of Governors in 1955 although he was sentenced at Nuremberg to eight years in prison. Otto Ambrose, another director who also ran the poison gas operations, was hired for a major position by J. Peter Grace, a major industrialist and leader of the U.S. Council of the International Chamber of Commerce.
