Re: Its "just" documentation
I was going to say it was a lot more people than Turing who would have been required, and not just mathematicians as well.
The other (ironic) problem is the official secrets act. A lot of people who had the information were bound by it, and took it seriously enough that the information went with them to their graves.
Even those who could have been tempted to share probably saw what happened to some who did (look up the story of Gordon Welchman) and were "dissuaded" from doing so.
All in all, the numbers of "presentations / papers" would be far less than it could have otherwise been.
It may be better to use the "second hand" (in most cases) information from the fine folk who still run Bletchley Park and similar establishments as historical sites of interest (I won't call it a museum).
Been there a couple of times, and the depth that some of the volunteers know both the history and indeed how the kit actually worked (well enough to make working recreations) is breathtaking.
But if nothing else, a pint raised both to those who did it all when the country needed them to, and those who keep the memory and technology alive for we who came later.
