You're thinking of Lorenz
This is a common mistake
"The enormous efforts undertaken to break Enigma-encrypted messages by the British at Bletchley Park, particularly the efforts of Alan Turing, pioneered much of what now stands as the basis for computer science."
The enigma codes were broken on an industrial scale using the "Bombe" (http://en.wikipedia.org/wiki/Cryptanalysis_of_the_Enigma#British_bombe), clever as they were I don't think the Bombe has ever been accused of being the basis of modern computing.
However the colossus (http://en.wikipedia.org/wiki/Colossus_computer) which was designed by Tommy Flowers to crack the Lorenz teleprinter encryption is another matter.
