Sadly, this brilliant scientist was prosecuted for his homosexuality at the time when it was still illegal in the United Kingdom and died of cyanide poisoning which was believed by his family to be accidental rather than suicide. In 2009, British Prime Minister Gordon Brown issued an official public apology for “the appalling way he was treated.”
