John Presper Eckert, a computer pioneer, was born April 9, 1919 in Philadelphia and died June 3, 1995 in Bryn Mawr, Pennsylvania.
Together with John W. Mauchly he constructed the ENIAC, sometimes considered the first digital computer (but see John Vincent Atanasoff for conflicting claims), from 1941-1945. Mauchly concentrated on the overall design while Eckert constructed the electronic circuits.
Both Eckert and Mauchly left the Moore School at the University of Pennsylvania in March 1946, mainly because of two reasons: (1) 1946 the University of Pennsylvania adopted a new patent policy to protect the intellectual purity of the research it sponsored - had Eckert and Mauchly stayed beyond March, the new policy would have required them to assign all their patents to the university, and (2) the conflict over widely-adopted term von Neumann architecture that ignores the developers of the ENIAC, viz. Mauchly and Eckert among others who also devised the stored-program concept when they understood the limitations of ENIAC. Eckert and Mauchly started up the Electronic Control Company which built the Binary Automatic Computer (BINAC). One of the major advances of this machine, which was used from August 1950, was that data was stored on magnetic tape rather than on punched cards.
Electronic Control Company soon became the Eckert-Mauchly Computer Corporation and it received an order from the National Bureau of Standards to build the Universal Automatic Computer (UNIVAC). In 1950, Eckert-Mauchly Computer Corporation ran into financial troubles and was acquired by Remington Rand Corporation. The UNIVAC I was finished in December 1950.
Eckert remained with Remington Rand and became an executive within the company. He continued with Remington Rand as it merged with the Burroughs Corporation to become Unisys in 1986. In 1989, Eckert retired from Unisys but continued to act as a consultant for the company.fa:پرسپر اکرت ja:ジョン・エッカート pl:John Presper Eckert
