While cracking Nazi codes at the Government Code and Cipher School at
Bletchley Park, Turing was instrumental in the design of the first
stored-program computers. See http://www.cranfield.ac.uk/ccc/bpark/ for
information on the museum that now occupies the Bletchley Park site where
computer conservationists have rebuilt the Colossus, the electronic code-cracker
Turing worked on.
