ENIAC John Mauchly J. Presper Eckert EDVAC University of Pennsylvania Moore School of Electrical Engineering serial-access memory memory
ENIAC inventors John Mauchly and J. Presper Eckert proposed, in August 1944, the construction of a machine called the Electronic Discrete Variable Automatic Computer (EDVAC) and design work for it commenced at the University of Pennsylvania's Moore School of Electrical Engineering, before the ENIAC was fully operational.  The design implemented a number of important architectural and logical improvements conceived during the ENIAC's construction, and a high-speed serial-access memory. However, Eckert and Mauchly left the project and its construction floundered.
