When the Nazis switched from machine-gunning their victims in large mass graves to marching their victims through gas chambers at Auschwitz, the gas that they employed was a chemical called Zyklon-B. Zyklon-B was developed by a small chemical company owned by IG Farben, a major supplier for Auschwitz and other death camps that funded many of the experiments undertaken by Mengele and other SS doctors. IG Farben profited handsomely because of the increased use of Zyklon-B.
