This guy?

"Five weeks before the outbreak of World War II, on 25 July 1939, in
Warsaw, the Polish Cipher Bureau revealed its Enigma-decryption
techniques and equipment to representatives of French and British
military intelligence, which had been unable to make any headway
against Enigma. This Polish intelligence-and-technology transfer would
give the Allies an unprecedented advantage (Ultra) in their ultimately
victorious prosecution of World War II."

Clearly not immediately relevant since it was much later that the German
Enigma code was broken.

How much did he contribute to this ....
