|Noun||1.||John von Neumann - United States mathematician who contributed to the development of atom bombs and of stored-program digital computers (1903-1957)|
|(person)||John von Neumann - /jon von noy'mahn/ Born 1903-12-28, died 1957-02-08.|
A Hungarian-born mathematician who did pioneering work in quantum physics, game theory, and computer science. He contributed to the USA's Manhattan Project that built the first atomic bomc.
While serving on the BRL Scientific Advisory Committee, von Neumann joined the developers of ENIAC and made some critical contributions. In 1947, while working on the design for the successor machine, EDVAC, von Neumann realized that ENIAC's lack of a centralized control unit could be overcome to obtain a rudimentary stored program computer. He also proposed the fetch-execute cycle.
