June 23, 2012, was the Centenary of Alan Turing’s birth in London. During his relatively brief life, Turing made a unique impact on the history of computing, computer science, artificial intelligence, developmental biology, and the mathematical theory of computability. 2012 was a world-wide celebration of Turing’s life and scientific impact, with a number of major events taking place throughout the year. A number of these were linked to places with special significance in Turing’s life, such as Cambridge, Manchester and Bletchley Park - while hundreds of other events were hosted in over forty countries, commemorating Turing in every continent outside Antarctica. The Turing Centenary Advisory Committee (TCAC), represented a range of expertise and organisational involvement in the 2012 celebrations, and continues to play its role in the ensuing impact underpinning further 'Alan Turing Years'. The Committee's founder was Professor Barry Cooper, supported by Computability in Europe, and a host of organisations and individuals, many represented on this page. We would be very grateful if those maintaining Turing webpages linked to here would help us keep a record of this amazing period in the 'Turing Renaissance', and make sure pages are archived, and we are notified of changed urls. Many thanks!
