The code breaking feats of the Bletchley teams led by Turing have been marginalised by the way that we've recorded and remembered our history. The great military exploits of WW2 - the B of B, the sinking of the Bismarck, the Atlantic campaign ("The Cruel Sea"), D Day - have understandably overshadowed the untelegenic activities of a bunch of boffins beavering away in a collection of huts. The need to preserve secrecy was for a long time another factor that served to preserve the Enigma secret
However, after the Bletchley story finally emerged some 10-15 years ago, one might have expected some posthumous recognition for Turing but to my knowledge it didn't happen.
A new building at the QinetiQ site at Malvern has been named after him - little reward I know but it's a start.
How should he best be honoured posthumously..?
