Modern Computation

Alan Turing made important contributions to early models of computation in the 1930s and 1940s; but his tragic suicide in 1954 prevented him from contributing to its later evolution. Maurice Wilkes, who passed away aged 99 in November of 2011, informed me of Turing's death during my final exam week at Cambridge in June 1954, where I was studying for the first postgraduate diploma in computer science ever offered anywhere in the world.

Computing models developed after the 1970s have moved well beyond the Turing machine model. My talk will discuss my recent edited book on Interaction Machines (Springer Verlag 2007) post-Turing later evolution of computing through personal computers, object-oriented programming and the Internet.
