Klaus Barbie

Nikolaus Barbie was a German officer of the SS and SD who worked in Vichy France during World War II. He became known as the "Butcher of Lyon" for having personally tortured prisoners—primarily Jews and members of the French Resistance—as the head of the Gestapo in Lyon. After the war, United States intelligence services employed him for his anti-communist efforts and aided his escape to Bolivia, where he advised the dictatorial regime on how to repress opposition through torture.
