Claude Shannon is not a name as familiar as Alan Turing, but his work on logic circuits (the building blocks of any computer), signal processing and cryptography earned him the title 'father of information theory'.
A war time contact with Turing impressed him and he proved that one-time pads could produce unbreakable codes. However, much of his work, like Turing's was classified until long after the war had ended.
Claude died in 2001 but it still seems fitting that we celebrate his contributions on what would have been his birthday.
