Indeed - the Enigma decoding machines at Bletchley were the evolution of earlier designs, two iterations at least that came from the Poles.

I mentioned Tutte as Bletchley can take full credit for the inhouse reverse engineering and attacks on Tunny, the Lorenz cipher, a more difficult cipher than Enigma and one used for more sensitive traffic by the Germans.

Tunny had an entirely seperate dedicated class of machines used for its attacks.

    Colossus is thus regarded as the world's first programmable, electronic, digital computer, although it was programmed by switches and plugs and not by a stored program.
