His contributions to Computer Science were for his work creating the first mordern computers. At the start of WW2, he and other people designed a code-breaking machine called bombes. At the end of WW2, Turing was scouted and recruited to the National Physical Laboratory to create the first electronic computer. But the NPL lost the race to do it.
Alan Turing in 1952 was arrested after reporting a burglary in his home. They investigated Turing to discover that he was in a relationship with a 19-year-old man named Arnold Murray. But they arrested Turing instead of helping him solve the burglary that happen. Alan Turing passed away due to cyanide poisoning, assumed to be suicide on June 7, 1954.
