John Mauchly and J. Presper Eckert

	John Mauchly envisioned the ENIAC. He was a professor of Physics at Ursinus College. In 1943 he attended a workshop at Penn. There, he saw the Differential Analyzer producing firing tables. Mauchly realized that he could build an electronic machine that could be much faster.
	J. Presper Eckert solved the engineering challenges. The chief challenge was tube reliability. Eckert was able to get good reliability by running the tubes at 1/4 power.

Together, they proposed the ENIAC to the Army in 1943. Construction was finished in 1946. For the next nine years, the ENIAC served as the primary computing engine for the Army. More details are available in the next section, the ENIAC in Action.
