I.G. Farben was a German chemical conglomerate that used slave labor during World War II. Twenty-three executives from I.G. Farben were brought to trial on charges of war crimes and crimes against humanity. Their offenses included the deportation and enslavement of civilians, notably at the Auschwitz concentration camp complex. The tribunal acquitted ten of the defendants completely. The thirteen defendants found guilty received prison terms ranging from one-and-a-half years to eight years, reduced for time already served while standing trial. One defendant, Max Brueggemann, was released due to illness prior to the indictment.
