Although I was living in my father's house and having dinner with him nearly every night during the decade following World War II, it was not until I read Aspray's comprehensive and insightful account that I fully understood the significance of what he and his colleagues were doing or the role he played in ushering in the computerized world in which we live and work today.

Although 'von Neumann architecture' is a familiar phrase, few people remember the breadth of von Neumann's imprint on early comuting. In this impressive, well-researched synthesis, Bill Aspray traces that imprint in computer design, computer applications, information theory, and von Neumann's consulting with business and government.

William Aspray has written the most interesting and detailed work that I have seen on John von Neumann and the origins of modern computing.
