Turing's legacy should indeed be more widely celebrated. Just a factual correction though: the enigma machine was the German cipher which generated the secret military codes. Turing worked on technology to break those codes, notably on a groundbreaking 'computer' called the bombe. He led the 'Hut 8' team at the Bletchley site. It is estimated that the work of the Bletchley codebreakers shortened the war by two years and saved 14 million lives. There are several other names from that era which deserve higher recognition as well.
Following WW2, the Bletchley Park site was eventually passed down to the Civil Aviation Authority who used it primarily for the training of ATC engineers. The grounds were filled with old radar heads and navaids. I had the good fortune to be sent on a two week familiarisation course there early in my career. At the time, the historic role of the site was still top secret ... the public (myself included) had no concept of what had gone on there. My accommodation was in one of the huts! Several huts were derelict ... you could just wander in them ... little did I know! In retrospect, I'd love to know the hut number used for our accommodation, but I very much doubt it was one of the historic ones. What I do recall clearly was that the site was littered with signs warning of a photography ban, and threatening dire punishments (including execution) for divulging secret information from the complex. We thought these signs highly amusing, as our course wasn't secret in any way. Now we know that those signs were a relic from the war years ... they had never been taken down.
I recently visited Bletchley Park again. It is now an excellent museum, and the wartime role of the site is public knowledge. When I mentioned to my friend and fellow visitor that I'd done a course there years earlier, eyebrows were raised! Must be some unlikely '007' James Bond figure! Sadly not ... just a lowly CAA staffer back in the '80's! But I do feel very privileged to have explored the grounds there in the site's semi-derelict state before the significance of those run-down huts was common knowledge. It is great to see them restored and appreciated now.
