Turing may not be a household name, but his achievements have been recognised.

A road has been named after him in Manchester, where he lived for the latter years of his life when he joined Manchester University.

There is also a bronze statue of him in Sackville Park in the city's gay village, where he sits on a bench, apple in hand.

He has even featured in a Doctor Who book.

And the home of his birth in London also has a blue plaque outside, which will now be joined by a plaque outside the place of his death on Adlington Road, in Wilmslow.
