Dr. Mengele was

. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.

At Auschwitz Josef Mengele did a number of medical experiments, using twins. These twins as young as five years of age were usually murdered after the experiment was over and their bodies dissected.

Mengele injected chemicals into the eyes of the children in an attempt to change their eye color. He carried out twin-to-twin transfusions, stitched twins together, castrated or sterilized twins. Many twins had limbs and organs removed in macabre surgical procedures, performed without using an anesthetic.
