Britain's £50 Note Will Honor Computing Pioneer Alan Turing

"The strength of the shortlist is testament to the U.K.'s incredible scientific contribution," Sarah John, the Bank of England's chief cashier, said in a statement. The bank plans to put the new note into circulation by the end of 2021. Bank of England bills feature Queen Elizabeth's face on one side, and a notable figure from British history on the other. Scientists previously honored in this way include Newton, Darwin and the electrical pioneer Michael Faraday. The current £50 features James Watt, a key figure in the development of the steam engine, and Matthew Boulton, the industrialist who backed him.
