Alan Turing was a brilliant English mathematician and logician. During World War II, he led the team at Bletchley Park that cracked the German Enigma code, an achievement that historians estimate shortened the war by at least two years and saved over 14 million lives.
"Sometimes it is the people no one can imagine anything of who do the things no one can imagine."
Impact
Despite his heroic service, Turing was prosecuted in 1952 for homosexual acts, which were then illegal in the UK. He was forced to undergo chemical castration and died by suicide two years later. It wasn't until 2013 that he received a posthumous royal pardon. Today, the "Turing Test" remains a benchmark for AI, and his image graces the UK £50 note, symbolizing a global recognition of both his genius and the injustice he endured.
