footnotes = John Adam Presper "Pres" Eckert Jr. (
April 9, 1919– June 3, 1995) was an American electrical engineer and computerpioneer. With John Mauchlyhe invented the first general-purpose electronic digital computer ( ENIAC), presented the first course in computing topics (the Moore School Lectures), founded the first commercial computer company (the Eckert-Mauchly Computer Corporation), and designed the first commercial computer in the U.S., the UNIVAC, which incorporated Eckert's invention of the mercury delay line memory.
Eckert was born in Philadelphia, Pennsylvania to a wealthy real estate developer John Eckert and was raised in a large house in Philadelphia's Germantown section. During elementary school, he was driven by chauffeur to
William Penn Charter School, and in high school joined the Engineer's Club of Philadelphia and spent afternoons at the electronics laboratory of television inventor Philo Farnsworthin Chestnut Hill. He placed second in the country on the math portion of the College Boardexamination.

Eckert initially enrolled in the
University of Pennsylvania's Wharton School to study business at the encouragement of his parents, but in 1937 transferred to Penn's Moore School of Electrical Engineering. In 1940, at age 21, Eckert applied for his first patent, "Light Modulating Methods and Apparatus".

Invention of the ENIAC
Dr. John Mauchly, then chairman of the physics department of nearby
Ursinus College, was a student in the summer electronics course, and the following fall secured a teaching position at the Moore School. Mauchly's proposal for building an electronic digital computer using vacuum tubes, many times faster and more accurate than the differential analyzer for computing ballisticstables for artillery, caught the interest of the Moore School's Army liaison, Lieutenant Herman Goldstine, and on April 9, 1943was formally presented in a meeting at Aberdeen Proving Groundto director Colonel Leslie Simon, Oswald Veblen, and others. A contract was awarded for Moore School's construction of the proposed computing machine, which would be named ENIAC, and Eckert was made the project's chief engineer. ENIAC was completed in late 1945 and was unveiled to the public in February, 1946.
Both Eckert and Mauchly left the Moore School in March 1946 over a dispute involving assignations of claims on intellectual property developed at the University. In that year, the University of Pennsylvania adopted a new patent policy to protect the intellectual purity of the research it sponsored, which would have required Eckert and Mauchly to assign all their patents to the University had they stayed beyond March.
Eckert and Mauchly's agreement with the University of Pennsylvania was that Eckert and Mauchly retained the patent rights to the ENIAC but the University could license it to the government and non-profit organizations. The University wanted to change the agreement so that they would also have commercial rights to the patent. In the following months, 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. The Electronic Control Company soon became the Eckert-Mauchly Computer Corporation and it received an order from the National Bureau of Standardsto build the Universal Automatic Computer (UNIVAC). In 1950, Eckert-Mauchly Computer Corporationran into financial troubles and was acquired by Remington RandCorporation. The UNIVAC Iwas finished on December 21, 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
Unisysin 1986. In 1989, Eckert retired from Unisys but continued to act as a consultant for the company. He died of leukemiain Bryn Mawr, Pennsylvania.
Some computer historians—and Eckert himself—believed that the widely-adopted term "
von Neumann architecture" should properly be known as the "Eckert Architecture," since the stored-program concept central to the von Neumann architecture had already been developed at the Moore School by the time von Neumann arrived on the scene in 1944-1945.
