For the Record,
PLEASE note I have no connection with Andrew Hodges, Author of the book I'm quoting from on Alan Turing (1912-1954) Mr. Hodges indeed is Alan's saving grace and his efforts will go miles and miles (and have done so) in relating to the world Alan's great achievement. Thank you Mr. Hodges for taking the time to document and 'save' Alan Turing for humanity.
There is NO OFFICIAL anything of Alan being Autistic but this took place well before even the very first era of Autism in the 1940s. People taking the time to read the book and learning of Alan will agree he was "autism." Author Hodges might have known for sure Alan was a little OFF as did Alan's friends but, thankfully no one in that era could call it autism. If they could label him anything, perhaps no one would have even cared to listen to his good ideas as they would have simply been form a "retard" and not worth a second thought. The Enigma might indeed be a double Enigma if this book also proves to be an early lesion in Autism. Please note as our experience has been "double-blind" so has Alan's so would be the experience of Mr. Hodges as well. Perhaps Alan would be pleased that his life might very well be an 'unsolved' Enigma even 50 plus years later?
