Eckert-Mauchly Computer Corporation (EMCC)
J. Presper Eckert and John Mauchly, the major figures in the creation of the ENIAC, left the University of Pennsylvania Moore School of Engineering at the end of WWII to found their own firm. They had hoped to be the first to exploit the new concept of the stored program computer, but were hampered by a lack of funds and, to some extent, by the bureaucracy surrounding their only major customer, the Census Bureau. They sought other investors but never had enough to properly complete their projects.
They eventually sold the business to Remington Rand (later Sperry Rand) who incorporated it as the UNIVAC division of the company. Eckert remained with UNIVAC all his life but Mauchly left after a few years to become a private consultant.
