(Sunday, May 30, 1943; during the The Holocaust, part of World War II) — German Schutzstaffel (SS) officer Dr. Josef Mengele, also known as the Angel of Death, today became the head doctor of the BIIe sector of Auschwitz II-Birkenau extermination camp in Nazi-occupied Poland, which was the family camp for Sinti and Roma prisoners.

Eager to advance his medical career by publishing “groundbreaking” work, Mengele began experimenting on live Jewish prisoners.

In the guise of medical “treatment,” he injected, or ordered others to inject, thousands of inmates with everything from petrol to chloroform.

Mengele, 32, also had a penchant for conducting bizarre surgical experiments on captive patients, focused primarily on twins, with no regard for the health or safety of the victims.

He was also a member of the team of doctors who selected victims to be killed in the gas chambers and was one of the doctors who administered the gas.
