The above named have innovated the concept of computability in the mid ninety-thirties. Alan Turing gave his definition of computability via a creation of a model of a universal stored program computer. The distinction between computable and non-computable functions was subsequently refined by a discussion of the inherent complexity of computable functions. The speaker will draw from his personal interaction with Church, Gödel and the people working with John von-Neumann a picture of the evolution of computing as well as give a perspective of the future of computer science and technology.
