Joan Clarke Murray codebreaker at Bletchley Park during World War II, became deputy head of Hut 8 in 1944. Code breaking was almost exclusively done by men during the war. Clarke was paid less than the men and felt that she was prevented from progressing further because of her gender. She was a English cryptanalyst and numismatist. You have Joan and the women of Bletchley Park to thank for changing the History of the World AND the fact that you’re reading this on a computer!
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.
Famed mathematician Alan Turing is the inventor of the technology that allowed computers to be possible, and is considered the creator of computers because of this. Every computer in existence has used his models and tech to exist. Unfortunately, he lived in a time where being homosexual was illegal and after a conviction against him for having relations with another man, he was subjected to horrendous conversion therapy and later committed suicide.
