And who broke the 'unbreakable' German Enigma code ?

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 ....

It's been rebuilt AIUI btw !


Futher info ......

Construction of a fully-functional replica[11] of a Colossus Mark 2 was
undertaken by a team led by Tony Sale. In spite of the blueprints and
hardware being destroyed, a surprising amount of material survived,
mainly in engineers' notebooks, but a considerable amount of it in the
U.S. The optical tape reader might have posed the biggest problem, but
Dr. Arnold Lynch, its original designer, was able to redesign it to his
own original specification. The reconstruction is on display, in the
historically correct place for Colossus No. 9, at The National Museum of
Computing, in H Block Bletchley Park in Milton Keynes, Buckinghamshire.



Who cares? Or is that the highest level computer design has reached
in 'Blighty'?
