Alan Turing and his machines - fresh insights into the enigma

It is fitting that the greatest code-breaker of World War Two remains a riddle a hundred years after his birth. Alan Turing, the brilliant, maverick mathematician, widely considered to be the father of computer science and artificial intelligence, invented an electromagnetic machine called the'bombe' which formed the basis for deciphering Germany's Enigma codes. The man himself has rather eluded definition: painted (too easily) as a nutty professor with a squeaky voice; as a quirky, haphazard character with a sloppy appearance by his mother and schoolmasters; by colleagues as a gruff, socially awkward man; and by his friends as an open-hearted, generous and gentle soul. The crucial contribution Turing made at Bletchley Park, one that has been credited with shortening the war by two years and saving countless lives, did not become public knowledge until twenty years after his death. His mother, brother and friends did not know until long after they'd mourned him, the extent of his heroism.
