Lorenz: Hitler's "Unbreakable" Cipher Machine

Many people have heard of Enigma before, the code machine used by Nazi Germany to send secret coded messages. Yet, some very clever code breakers were able to break that code and read those messages! But there was another cipher machine used by the Germans in WWII called the Lorenz machine, and this machine was even more difficult than Enigma, and was used by the top level of the Nazi Party. However the code breakers at Bletchley Park broke this code too, and could read secret messages from people like Adolf Hitler himself! It was mathematician Bill Tutte who discovered the breakthrough that allowed the Lorenz code to be broken. On the 10th of September 2014 a new memorial to Bill Tutte is unveiled in his hometown of Newmarket. Have a look at the Bill Tutte Memorial website at http://billtuttememorial.org.uk/
