Turing who cracked the enigma code for Great Britain

Well - he NOT cracked it alone or first. Without work of French intelligence and Polish cryptologists: Rejewski (https://en.wikipedia.org/wiki/Marian_Rejewski), Różycki and Zygalski Enigma wouldn't be cracked in useful time. And Turing-own decrypting machine was too slow, he had to cooperate with Gordon Welchman (https://en.wikipedia.org/wiki/Gordon_Welchman)
