Welcome to the ACM Turing Centenary Program

Abstract

Alan Turing’s wide-ranging interests ranged from the purely theoretical to the eminently practical. He contributed to our fundamental understanding of what can be computed through the invention of what we now refer to as the Universal Turing Machine. On the practical side, his work on the design of the ACE (Automatic Computing Engine) drew upon his wartime experience at Bletchley Park and blazed trails toward the breakthrough technology of stored-program computing.
