Alan Turing, the man who broke the enigma code during WWII, is estimated to have shortened the war by over two years, and to have saved over 14 million lives. He was later charged for his homosexuality and was forced to undergo chemical castration.
Tragic but true - Alan Turing is widely considered to be the father of computer science. In WW II he decrypted German encoded messages. Winston Churchill said that Turing made the single biggest contribution to Allied victory in the war against Nazi Germany. After the war he was tried in court for being gay, found guilty, forced to take castration pills, and then driven to suicide. Britain has apologized. ~Via Pat Whitten
