23 Medical Professionals Who Were Actually Murderers
Shiro Ishii
Dr. Shiro Ishii was the director of Unit 731, the department of biological weapons for the Imperial Japanese Army during World War II. Unit 731 would experiment on Chinese POWs and civilians, giving them deadly diseases and testing horrible biological weapons upon them. The unit would also perform vivisection on live prisoners, and subject them to artificially induced strokes, heart attacks, frostbite, and hypothermia to track how they would die. Ishii avoided war crimes prosecution by turning the results of his experiments over to the U.S. Ultimately, he died of throat cancer at the age of 67 in 1959.
