J. Presper Eckert From Wikipedia, the free encyclopedia. John Presper Eckert , a computer pioneer, was born April 9 in Philadelphia and died June 3 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 . 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 October . They 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 , 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 , Eckert-Mauchly Computer Corporation ran into financial troubles and was acquired by Remington Rand Corporation. The UNIVAC I was finished in December 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

John W. Mauchly J. Prespers Eckert Table of Contents I Claim to Fame II Research/Career highlights III Trivia IV Bibliography I Claim to Fame John W. Mauchly and J. Presper Eckert were the two principle inventors of the ENIAC computer,the first large-scale general-purpose electronic computer. ENIAC is an acronym for "Electronic Numerical Integrator and Computer," built at the University of Pennsylvania's Moore School of Electrical Engineering.As a general-purpose computer to solve a wide range of calculations,this distinguished the ENIAC from earlier automated calculating machines designed for single problem-solving applications.They began the ENIAC in 1943 and completed the ENIAC in 1946. The ENIAC was introduced to the public on Valentine's day,14 February 1946. The ENIAC 's technical specifications : took up 3,000 cubic feet weighted 30 tons used 18,000 vacuum tubes and 70,000 registers required more than 170 kilowatts of power had a random access memory capacity of about 1,000 information bits used punched cards to store data The ENIAC was used by the U.S. Army for military calculations in the World War II.

The Moore School was by this time heavily involved with research specifically directed towards the war effort. Eckert taught a defence course at the Moore School and one of his students on the course was John Mauchly . It might seem strange that Mauchly , who was twelve years older than Eckert, should be his student. Mauchly was already an established academic teaching physics but he became involved in defence training as part of his contribution to the war effort. Eckert quickly became interested in Mauchly's ideas for the development of computers and for a while the two discussed these ideas frequently. Soon, however, Eckert moved on to undertake other military work at the School. Ashurst [2] relates how Eckert was:- .... eventually involved with work on ultraviolet light and the development of the means to measure metal fatigue. Later, he went on to develop a method for measuring small magnetic fields to be used in detecting marine mines. He then went on to work on the electronics of radar and target locating and following equipment; these devices played a decisive part in weaponry, and their development and construction was considered to be of the very highest priority.

Presper Eckert Background David Allison (DKA): Let's go back to 1943 and the circumstances that surrounded the invention of this machine. How do you remember the environment? JPE: I don't know what you mean when you say how do I remember the environment. DKA: Was it a pressured environment? How was the problem originally presented to you? Peter Vogt: Why did they stop you? What was important about it that they put you on to? Set the stage for us. JPE: What happened is that during World War II, a number of large guns, field pieces, were sent over to Africa. Tables were sent with them, telling them where to set the dials on the gun to allow for the amount of wind blowing and the height of the elevation of the target, with the expectation that the shell would land where you wanted it to when you followed the prescription in the book. The shells did not land where you wanted them to. The people down there using these guns were having to make guesswork corrections on the tables to hit anything, not very satisfactory in the middle of a war. The trouble was traced to the fact that the ground was more resilient in Africa, due to the type of vegetational growth in the jungle.

Exhibitions Many important objects from the Computer History Collection are on exhibition in Information Age: People, Information and Technology , a 14,000 square foot display on the first floor of the National Museum of American History. Opened in May 1990, the exhibition surveys the history of information technology and its relation to society from the origin of the telegraph to the present. The display has over 900 original artifacts. They include Samuel Morse's telegraphs, Alexander Bell's telephones, a Hollerith punched card machine, a 4-rotor German ENIGMA encoder used during World War II, the ENIAC computer, the TELESTAR test satellite, an automotive welding robot, a selection of early personal computers, and digital high definition television. With 50 interactive computer and video display, Information Age is also the Smithsonian's most interactive exhibition. Theme Information Age centers on the technical evolution of electrical and electronic information technology. The telegraph began a revolution in communications by transmitting information in electrical form instantly to distant locations. This new phenomenon of instant information was later expanded by the telephone, radio and television. Then the digital electronic computer made it possible to process information instantly. As the computer developed and matured, communication and processing technologies were joined into networks that now stretch around the world, affecting all areas of global society.

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. Photograph of John W. Mauchly, ca. 1940-50. We attempt in this exhibition Recommended texts, currently in print, to learn more about ENIAC and the development of the personal computer:

J. Presper Eckert, John W. Mauchly and ENIAC (Continued) Calculating ballistic results was creating a bottleneck and John Mauchly proposed the construction of an electronic computer to eliminate this bottleneck. The person most taken by Mauchly's ideas was a young electronic engineer named, John Presper Eckert. After several attempts to get this proposal accepted by the BRL, they finally received the okay in 1943. ENIAC was Eckert and Mauchly's project. Eckert was the engineer, Mauchly was the visionary. Eckert recruited the top graduate students from the Moore School. Engineers were each assigned a space at a worktable that ran around the backroom of the school, while assemblers and wiremen occupied central floor space. Problems and dead-ends occurred so in 1944, John von Neummann was brought in as a consultant. Next Page

Presper Eckert's Childhood Pres Eckert was born on April 9, 1919 in Philadelphia. He was the only son of a prominent real estate developer and contractor and grew up in the Germantown section of town. He was christened by Russell H. Conwell, the charismatic Northern Baptist minister, founder of Temple University and author of the famous "Acres of Diamonds" motivational speech. His father consulted on construction projects in America and Europe combining business trips with family vacations, usually in the summer. By the time he was twelve years old Pres had traveled over 125,000 miles, visiting all 48 states, Alaska, most of Europe's great cities, and Egypt. As a result the collection includes many photos of Pres as a child in exotic locations and with some famous individuals. Pres went to The Penn Charter school in Germantown and developed a reputation as a math wiz and electronic genius at an early age as a result of his tinkering with radios and other electronic devices. An early radio he built as a child is included in the collection.
