Alan Turing's Notes Found After Being Used As Insulation At Bletchley Park 121

An anonymous reader writes: In 2013, a restoration project for Hut 6 of Bletchley Park uncovered a collection of papers being used as roof insulation. The papers were frozen to preserve them while they were inspected and repaired. Now they're on display at an exhibition showing items found during the restoration process. "The documents also included the only known examples of Banbury sheets, a technique devised by [Turing] to accelerate the process of decrypting Nazi messages. No other examples have ever been found. All the findings are unique as all documentary evidence from the codebreaking process was supposed to be destroyed under wartime security rules."

    First they persecute him for being gay, then they assassinate him, and finally they use his notes as insulation.

    Those British pommy bastards are pure evil, and they deserve to have their rotten Empire collapse around their ears.

        This kind of thing has happened before. Some years ago (I cannot recall actual wording, read this years ago) an late 1800s old house was being remodeled. Crews found newspapers and many documents lining the framework under wall paneling. Back in the days it was common to use newspapers and other papers for insulation. Obviously they found some very old newspapers but also a original copy from late 1700s (or was it early 1800s) document. I can't remember how the story went, either one of Thomas Jefferson's p

    • Almost certainly the result of someone rescuing some paper from a bin to reuse in the insulation - the notes were "destroyed" as required, but re-purposed into another process.

    • It was mostly just scribbling, and notes taken during decription. They had reams of the stuff that was no longer useful. This seems like mostly routine day-to-day stuff that would have been seen as having zero value a couple of days later. Probably installed while Hut 6 was actually active. They had heaps of papers that had no actual use other than insulation material.

    Other than the obvious impact Turing's work had in the war effort, did people at Bletchley have any idea how valuable his work would be more generally? My computer science peers are quite good at explaining how their work might have value and impact. Indeed, a lot of scientists these days start publications by providing this context. But is the same true in the first half of the twentieth century and in the middle of a world war? It might well have been the case that his notes were genuinely believed to have more value as insulation.

      "Alan Turing's notes" is somewhat overselling it. They're not talking about a white paper: Bletchley would have produced hundreds of sheets of these kind of scrap workings every day, so they were genuinely worthless then. They're only worth anything now because all of the rest were destroyed. To put it in perspective, they're more valuable to us than a shopping list from that era would be, but less valuable than a shopping list from ancient Sumeria would be.

      • so they were genuinely worthless then

        I think what you're trying to say is that they had served their original purpose. If they were worthless at the time, the military would not have gone out of their way to ensure none of it survived the war. Note that after the war the "five eyes" kept a lid on their wartime code breaking technology until the 1970's, long after Turing's death they were using it to listen in on friends and foes who had no idea such sophisticated code cracking techniques were even possible.

        • There was an exception; the extensive Pearl Harbor hearings shortly after the war revealed the breaking of the main Japanese naval code. It is interesting to go through history written through the 1960s and notice things that just happened to go well for the Western Allies because they "guessed right".

The GCHQ had moved onto helping the US with its difficult Korean war issues. By the 1950's Turing's role in ww2 and his 1950's travel was seen a huge security risk.

        Churchill ordered all material at Bletchley to be destroyed (both paperwork and hardware like several Colossus computers) not primarily because of the security risk. It was highly unlikely that any other foe would use the same encryption method as the Germans had.

        It was because Churchill did not want the credit for winning the war to go to a handful of boffins rather than to the armed forces. This was for reasons of public morale; hundreds of thousands had died in combat and air raids, and everyone had lived in austerity for years. He did not want people to think that all that sacrifice had been pointless because in the end the war had really been won by "some university-type egghead smart-arses using dirty tricks" - because that is how the majority of the public would have seen it.

        If you doubt how that is how most people would have seen it in 1950, just fast-forward and think of how most people see the activities of the NSA today.

          Another reason was the US and UK had got the German OKW-Chi work on from the Target Intelligence Committee teams (TICOM) on the Russian Fish system.
          A Soviet military teleprinter that used packet switching was then open to the US and UK in 1945 thanks to German efforts during ww2.
          Later efforts by German teams in the UK helped with the Caviar project but only got Soviet administration messages.

          Are you implying that Bletchley Park was spying against their own people? Because that's what's wrong with the NSA, not the fact that they're "egghead smart-asses," or the fact that they're spying. The NSA spying against foreign enemies* is just fine.

            Yes, there is the problem of collusion like Five Eyes. So... you write a law requiring that a) all spies on our soil need to be apprehended if they are found and b) that we are not permitted to use material from foreign intelligence against internal parties unless there is a specific, clear, and present danger or during wartime.

          Not really, and the credit goes to both the fighters and the thinkers. Aside from being the key to sinking the entire U-boat fleet in the N. Atlantic by informing the fighters where the subs would surface, this is the same technology that was used to arrange a more famous naval ambush known as the battle of midway. Churchill and his allies didn't want anyone to know about the techniques because it was a huge military and economic advantage, even the fact they existed was kept a secret, so much so that very

      There were many different types of people there, but the majority would almost certainly be so worried about living to the end of the week, that "long term" was probably next month for of them.

      Unlikely, Turing's work was so useful to the war effort that Churchill basically gave him a blank cheque. It's doubtful the military brass knew anything about the insulation, if they did they would have probably burnt down the entire building just to be sure all the papers were destroyed. Sounds much more like the act of a bunch of engineers and boffins, ie: "To hell with idiotic military secrecy, I'm not putting out the top secret recycling this week, there are no Nazi's in the ceiling and I'm freezing my

    The notes will be restored and then popped into a glass display case with one or two pages visible, with a sort-of description of why they are important.

    Pretty much all of Bletchley is like this, unfortunately. Stuff on display that you are not going to understand, such as copies of Turing's early mathematical papers with only the first page showing.

    The problem with the whole Bletchley Park experience is that it was obviously extremely important, but is practically beyond all explanation for the ordinary punter. I think I might be able to intellectually struggle through an explanation of some of it, but the displays do not explain it in enough detail to help with that. Overall, my visit felt like a patchwork of different explanations of the same few concepts using poster boards, audio devices and video and interactive displays. It's padded out with various "wartime experience" bits here and there.

    It probably seems like a very negative attitude, but a technical chap in his mid-forties with a couple of bright teenagers in tow ought to be right in the target demographic for Bletchley, but I'm practically embarrassed to say that I ended up drinking weak hot chocolate in the cafe and agreeing with my boys that it was all rather dull.

    Special commendation for the rack of old bicycles at the end of one of the huts, with a hidden speaker to give you the authentic experience of what squeaky bicycle wheels sounded like in the 1940's. Or something?

      Visited the National Cryptologic Museum (on the same campus as the NSA, just off 295 in Maryland) about a decade ago. I and my then-girlfriend were probably the only visitors in the entire building, and the staff were pretty excited to see us. They even let us try out the German Enigma machine they had on display - no glass display case at that time! Don't know if it's changed in the last ten years, though.

      As opposed to forcibly enslaving millions of people around the world through several centuries of colonial rule? If you're going to lay a guilt trip on Britain, what about the US with it's legacy of slavery? And good heavens, look at the evils perpetrated in communist Russia, or Germany and Japan during the war years. Look, every country has their black marks, and some are pretty damn black indeed. If you're going to collectively assign guilt to future generations, it will never end. Ever. Future generations will also look at us and sadly shake their heads, I'm sure. We learn from the past, we forgive, we try to make things right as best we can, and we move on.
