Alan Turing on new Bank of England's £50 note

Ten years ago I started writing a book, called The Universal Machine, in which Alan Turing was the central character. The book was published in 2012 to coincide with the centenary of Turing's birth. Around the world, computer scientists and people from the LGBQT community got together to raise public awareness of this remarkable man. A decade ago few members of the public could say who Turing was. That has now changed. A public apology from the Prime Minister was followed by a pardon, which was followed by a pardon of all those convicted under the gross indecency law. An acclaimed movie, The Imitation Game, and many other initiatives have resulted in Turing now being recognised as a genius, "the Father of Computing."
The BBC recently reported that Turing will be the new face on the £50 note. He sits along with others such as Darwin and Newton on British banknotes.
