Abstract :
Aspray emphasizes von Neumann´s critical role in the formation of modern computing and celebrates von Neumann as the scientific legitimizer of computing. He provides a survey of von Neumann´s many important contributions to computer architecture, hardware, design and construction, programming, numerical analysis, scientific computation, and the theory of computing. Aspray´s essay stresses especially the importance of von Neumann´s work to promote the development of logical design.
