Having visited Bletchley Park last week I just had to visit the memorial to legendary WWII codebreaker Alan Turing on my brief trip to Manchester. The sculpture is by Glyn Hughes is at Sackville Gardens off Canal Street. Manchester University, where Alan worked after Bletchley Park, is behind him.
The cast bronze bench carries ithe text “Alan Mathison Turing 1912–1954” and the motto “Founder of Computer Science” as it would appear if encoded by an Enigma machine; ‘IEKYF RQMSI ADXUO KVKZC GUBJ’. However this is an artists impression of an Enigma encryption, rather than an actual one. As I learnt at Bletchley Park last week Enigma could not encode a letter as itself and on the bench there is a letter “U” at position 14 of both the plain-text and the cipher thus betraying it as not a true Enigma cipher.
