London:World War II hero Alan Turing who played the role of a codebreaker was selected by the Bank of England to feature on the 50-pound note.
During the war, Turing used to crack Nazi Germany's secret communication codes which proved to be a great help to win the war but later he was prosecuted under the charges of homosexuality which was illegal at that time.
He died at age 41 in 1954 after eating an apple laced with cyanide. He received a posthumous royal pardon in 2013.
