Juni in Bryn Mawr, Pennsylvania) war ein US-amerikanischer Computerpionier. Zusammen mit John W. Mauchly konstruierte er den ENIAC . Mauchly konzentrierte sich auf das Gesamtdesign während Eckert die elektronischen Schaltkreise entwickelte. Die Eckert-Mauchly Computer Corporation erhielt bald darauf vom National Bureau of Standards Eichamt ) den Auftrag, den ersten kommerziell produzierten Computer, den Universal Automatic Computer UNIVAC ), zu bauen. Nachdem die Eckert-Mauchly Computer Corporation in finanzielle Schwierigkeiten geraten war, wurde sie von der Remington Rand Corporation gekauft. Im Dezember war die UNIVAC I fertig. Eckert blieb bei Remington Rand, später Sperry und Unisys und bekleidete eine leitende Position im Unternehmen. verließ Eckert Unisys, stand dem Unternehmen aber weiter als Berater zur Verfügung.

Aiken sah sich in der Nachfolge von Charles Babbage. Es gelang ihm, gemeinsam mit den Entwicklungsingenieuren der IBM eine elektromechanische, programmgesteuerte Großrechenmaschine zu realisieren. Bis zum Jahr 1956 berechnete "Bessie" im Computation Laboratory der Universität von Harvard Tafelwerke mathematischer Funktionen. Eckert war ein "electronics wizard", der schon als Schüler Geräte und Verstärker mit Röhren gebaut hatte.

104. The First General-purpose Electronic Computer -- ENIAC ENIAC, which was the brainchild of John William Mauchly and J. presper EckertJr., was a monster. It was 10 feet tall, occupied 1000 square feet of floor http://www.maxmon.com/1943bad.htm

1943 AD to 1946 AD The first general-purpose electronic computer By the mid-1940s, the majority of computers were being built out of vacuum tubes rather than switches and relays . Although vacuum tubes were fragile, expensive, and used a lot of power, they were much faster than relays (and much quieter). If we ignore Atanasoff's machine and COLOSSUS , then the first true general-purpose electronic computer was the electronic numerical integrator and computer (ENIAC) , which was constructed at the University of Pennsylvania between 1943 and 1946. ENIAC, which was the brainchild of John William Mauchly and J. Presper Eckert Jr., was a monster. It was 10 feet tall, occupied 1,000 square feet of floor- space, weighed in at approximately 30 tons, and used more than 70,000 resistors, 10,000 capacitors, 6,000 switches, and 18,000 vacuum tubes. The final machine required 150 kilowatts of power, which was enough to light a small town. a One of the greatest problems with computers built from vacuum t ubes was reliability; 90% of ENIAC's down-time was attributed to locating and replacing burnt-out tubes. Records from 1952 show that approximately 19,000 vacuum tubes had to be replaced in that year alone, which averages out to about 50 tubes a day! a During the course of developing ENIAC, Mauchly and Eckert recognized a variety of improvements and new techniques, which they determined to use in any subsequent machines. For example, one of the main problems with ENIAC was that it was hard-wired; that is, it did not have any internal memory as such, but needed to be physically programmed by means of switches and dials.

The company was founded by John Mauchly and J. Presper Eckert who in 1946 had designed the giant ENIAC computer. Forty-six UNIVAC's (Universal Automatic Computers) were sold, and the system was used to accurately predict the 1952 election, although the results were not immediately reported by Walter Cronkite because they were not believed to be accurate. Democratic presidential candidate Adlai Stevenson was the front-runner in all the advance opinion polls, but by 8:30 p.m. on the East Coast, well before polls were closed in the Western states, UNIVAC projected 100-to-1 odds that Dwight D. Eisenhower would win by a landslide, which is in fact what happened.

John W. Mauchly and the Development of the ENIAC Computer An Exhibition in the Department of Special Collections Van Pelt Library, University of Pennsylvania by Asaf Goldschmidt and Atsushi Akera Department of History and Sociology of Science University of Pennsylvania Introduction The year 1996 marks the fiftieth anniversary of the ENIAC computer, the first large-scale general-purpose electronic computer. Built at the University of Pennsylvania's Moore School of Electrical Engineering, ENIAC is an acronym for "Electronic Numerical Integrator and Computer," but its birth lay in World War II as a classified military project known only as Project PX. The ENIAC is important historically, because it laid the foundations for the modern electronic computing industry. More than any other machine, the ENIAC demonstrated that high-speed digital computing was possible using the then-available vacuum tube technology. General View of the ENIAC, 1946.
