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.
The 50-pound note which is considered as the UK's highest denomination note under the Bank of England's collection will be the last to be redesigned and switched from paper to more secure and durable polymer after it enters circulation in 2021.
The redesigned 10 pound and 20-pound denominations feature author Jane Austen and artist J.M.W. Turner.
