This festering bubo in the armpit of humanity was the "medical director" of the infamous Japanese Unit 731. 

In pursuit of the deadliest possible biological warfare agent, and with a hearty dose of sheer sadistic curiosity, he performed his experiments in the spirit of true egalitarianism: on prisoners of war; on Chinese, Soviet, Indian, British and American troops; on civilians in the surrounding countryside. On anyone he could get his hands on.

Caveat Auditor: This man's deeds are so odious that it's painful to research them and difficult to hear them. Not kidding.
