石井 四郎 (Shirō Ishii) was a surgeon in the Japanese Army, making the rank of General and earned the Order of the Golden Kite, Fourth Class. He committed war crimes, but made a deal with the U.S. to give what he learned for his freedom. The U.S. accepted. He died of throat cancer.
I am writing a paper about him for class, but can't seem to find anything on his early life, save for when/where he was born. The earliest thing after that is he went to Kyoto Imperial University to study medicine. Then when he was commissioned into the army in 1921.
Do we know anything of his early life apart from what I mentioned? When did he start medical school?
