Tony Sale's Codes and Ciphers in the Second World War:
The history, science and engineering of cryptanalysis in World War II
Between 1939 and 1945, the most advanced and creative forms of mathematical
and technological knowledge were combined to master German communications.
British cryptanalysts, Alan Turing at the forefront, changed the course of
the Second World War and created the foundation for the modern computer.
In 1991 the Bletchley Park, the wartime home of Allied code breaking, was
saved from destruction by Tony Sale and some colleagues. They transformed
it into a museum devoted to the recognition and reconstruction of this crucial
aspect of world history, which had remained completely secret until the early
Tony Sale's Walking Tour of Bletchley Park, with some 50 photographs:

Among many books about Bletchley Park, the novel Enigma, by Robert
Harris, depicts bleary codebreaking toil and dreary Bletchley facilities
better than a recent a TV show based on the book.
