Peter J. Denning

Peter J. Denning (born 1942) is an American computer scientist and prolific writer. He is best known for pioneering work in virtual memory, especially for inventing the working-set model for program behavior, which addressed thrashing in operating systems and became the reference standard for all memory management policies. He is also known for his works on principles of operating systems, operational analysis of queueing network systems, design and implementation of CSNET, the ACM digital library, codifying the great principles of computing, and most recently for his book The Innovator's Way, on innovation as a set of learnable practices.
