Auschwitz Birkenau became the killing centre where the largest numbers of European Jews were killed during the Holocaust. After an experimental gassing there in September 1941 of 850 malnourished and ill prisoners, mass murder became a daily routine.

He made experimental surgeries performed without anesthesia, transfusions of blood from one twin to another, isolation endurance, reaction to various stimuli. And injections with lethal germs, sex change operations, the removal of organs and limbs, incestuous impregnations ...
