Josef Mengele

Joseph Mengele's name was on the rise because he became one of the doctors who supervised the selection of prisoners who come, to determine who should be killed and who became slave laborers. He also conducted human experiments on that camp inmates. People who knew Mengele, called him 'Angel of Death' because some human life was in his hands.
At Auschwitz, Mengele conducted a study in twins. After the experiment was completed, the twins were usually killed and their body was dissected.
He oversaw the operations of two Gypsy children sewn together to create conjoined twins. Hands of the children were infected, and their veins were damaged.
Mengele notoriously became rabid with blood of twins, especially identical twins. According to news, he took their blood to death.
