Alan Turning, if that name sounds a little unfamiliar he was one of the leads on the enigma machine during the second world war. He was very interesting I would just look him up if you wanted some reading.
I could not find a digital link, and they mention the national archives so you might have to go for a drive to see them. There might still be valuable information in the papers, but they were focused on preparing settings on the enigma machine to ready it for work.
