Cambridge University Press have just announced they are republishing a biography of Alan Turing written by his mother Sarah. The book was originally published in 1957 but the "Centenary Edition" includes a new forward and a new memoir by Turing's brother. The original book has been out of print for years and hard to track down. The publisher also says, "The contrast between this memoir and the original biography reveals tensions and sheds new light on Turing's relationship with his family, and on the man himself."
In a striking coincidence the new edition's cover shares strong design elements with The Universal Machine's cover, namely the red apple with a bite out. Frankly I'm a bit surprised that a book by Sara Turing would use this cover image, since Sara always refused to accept that her son had committed suicide, preferring to believe it had been a tragic accident. Whereas for my book the apple was the perfect image since it not only references Turing, but also Apple, the company, which features prominently in several chapters.
