Alan Turing

Memorial sculpture of Alan Turing in Sackville Gardens, Manchester -

"Turing has been depicted by sculptor Glyn Hughes as a scruffily dressed, ordinary man, holding an apple. The apple represents Newton, the tree of knowledge and forbidden love as well as being a reminder of Turing's death. Hughes buried his old Amstrad computer under the plinth as a tribute to "the godfather of all modern computers"."

He doesn't look all that scruffy to me!
