In 2019 it was announced that Alan Turing would appear on the new Bank of England 50 GBP note. The design shows him in front of an electronic computer that resembles a Colossus II--a computer of the type that Turing used to decipher Enigma code during World War II. The computer plans in the background of the note include a delay line memory--an early electronic memory for a stored program computer that did not exist during World War II.
