Let us re-write the caption like this:īromide print taken on 29 March 1951, one The portrait is by Elliott & Fry a bromide print taken on 29 March 1951, one of three from the National Portrait Gallery collection “The spy agency, which believes setting puzzles gives the public an insight into its surveillance work, said it thought the multi-part “Turing challenge” would take an experienced puzzler seven hours to complete.” Keep in mind that you need to solve puzzles 1 to 11 in order to get a shot at the final meta-puzzle 12! If you then selected the 8th letter of each answer, you obtain: The answers to these questions are quite obvious but the result for the 8th column is already puzzling! Hence the importance of the 8th column below!
The stylistic 8s in the pattern above the bank building on the front of the note refer to Hut 8, one of the sections of GC&CS. A two-word answer, nine letters then four, is required. The questions begin with a relatively straightforward crossword-style puzzle that starts by asking where GCHQ’s predecessor agency, where Turing worked, was based during the second world war. Crack the answers to the first 11 puzzles which should give you 11 single words or names which you’ll need your very own Enigma simulator to decode! Ready? The Turing Challenge requires you to solve a string of puzzles which get increasingly difficult. Turing’s housekeeper found him dead on 8th June 1954 but he had committed suicide the previous day. It has been estimated that his work shortened the war in Europe by more than two years and saved over fourteen million lives.Ī quick comment - GCHQ writes: “On the 8th June 1954, Alan Turing took his own life.” His life was one of secret triumphs shadowed by public tragedy. “This is only a foretaste of what is to come and only the shadow of what is going to be.”Īlan Turing - Interview to The Times newspaper on 11 June 1949.Īlan Turing was a mathematician, cryptographer and pioneer of computer science who possessed one of the greatest brains of the 20th century.
