ENIAC At U Penn
In 1946 the Moore School in Philadelphia, Pennsylvania was at the center of developments in high-speed electronic computing. On February 14 of that year it had publicly unveiled the ENIAC, the first general-purpose electronic digital computer, developed in secret beginning in 1943 for the Army's Ballistics Research Laboratory. Prior even to the ENIAC's completion, work had begun on a second-generation electronic digital computer, the EDVAC, which incorporated the stored program model. Work at the Moore School attracted such luminaries as John von Neumann, who served as a consultant to the EDVAC project, and Stan Frankel and Nicholas Metropolis of the Manhattan Project, who arrived to run one of the first major programs written for the ENIAC, a mathematical simulation for the hydrogen bomb project.
