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

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."

      Just to be clear, people in military establishments like Bletchley Park did wipe their arses on discarded papers, and such places often used earth closets for the people working in the huts. Only the big-wigs in the main house would have been able to use its WCs. Even confidential papers were used, because it was assumed that no-one would have the stomach to read them afterwards.

      That is the origin of the word (in English English at least) "bumf" for paperwork - bum fodder.

      Of course, spies did salvage the used bumf and read it, so the practice of taking a handful of paper from the wastepaper basket with you to the latrines was banned after a while. Presumably by then it had also been used as roof insulation, but that had been forgotten.

    It was mostly just scribbling, and notes taken during decription. They had reams of the stuff that was no longer useful.

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.

      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.

      Considering that we have a lot less of even the "throwaway" from Sumeria, a "shopping list" would have told us a certain amount about their actual eating habits and customs, as well as what hair products they used to get those fabulous hairstyles.

      It's (relatively) easy to find great literature or buildings or monuments from ancient times, they are built to last or adopted by other cultures and passed down. What is hard is finding stuff that really gives insight into how people actually lived. It would be worth more than Turing's notes only because the Sumerian equivalent of Turning's notes, kept to fill in a hole for someone's hut, have not come to light in 5000 years of history since then and probably would have disappeared in just a couple decades after it was put to that use.

    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.

    Tommy Flowers, .... was a British engineer. During World War II, Flowers designed Colossus, the world’s first programmable electronic computer, to help solve encrypted German messages.

    Funny, I was going to mention Tommy Flowers in a post above. I find it a bit odd that people today have focussed on Turing as the hero of that time; I cannot help wondering if it's because of the gay angle. As you say, Flowers built the first computer than can be called modern - electronic, programmable, general purpose. Yet hardly anyone has ever heard of him.

    At the time Bletchley Park seemed to be divided into two "camps" and Flowers was up against some influential opponents. One described Colossus as "a waste of good valves".

    Flowers even put some of his own money into building the first Colossus (there were several), for which he was never fully re-imbursed, although after the war he did get a small award. What a far cry from the billions made by Jobs, Wang, Gates & co two generations later. Churchill's order to destroy the Bletchley Park paperwork and hardware left a near vacuum in the history of computing - there are many people today who even think Bill Gates invented computers, FFS.

    Absolutely no disrespect to Mr Flowers:

    The computer was the tool.

    The code was cracked not by tools alone, but by mathematical insight, luck, sloppiness on the other side and a number of factors.

    So while Flowers was undoubtedly the engineer that could build the machine to automate the calculations that were being done, the actual calculations and WHY they worked were the part of Turing and others. And in the process he added a whole new branch to the mathematics of the time (which we now call Computer Science).

    Turing dreamed it, Flowers built it, but it's hard to imagine the machine being much use without the maths - the code was broken by complicated mathematical analysis of the mistakes made, basically, and was brought into the realm of the feasible by mathematical shortcuts and spotting of dead-ends. However, the maths could be applied - albeit slowly - to the code even without computers.

    Turing made it theoretically possible. Flowers made it practically possible - by building the machine that actual tried to do it, and did it fast enough to be useful.

    Both deserve respect.
