We all know that the English invented everything but I read years ago that the Enigma code was first broken by a Polish person who passed it on to French intelligence who in turn passed it on to the English.

This detracts nothing from Turing;s achievements.

As an interesting aside, Turing had a colleague and they experimented with robots .
When this colleague retired he thought it would be interesting to look at the earlier models which were that simple anybody could build one.

But, he had no chance, all was classified.
