His father brought home a Dietzgen slide rule and young John's interest was captivated. He read the manual of how to use the slide rule and became fascinated with the underlying mathematical principles. With his mother's help, he began self-study of a college algebra book from his father's library. The family moved to Florida where John attended high school and graduated in only two years, receiving straight A's is all of his science and math courses. He did some work to accumulate funds and delayed his entry to university for short while. He received a Bachelor of Science degree in electrical engineering from the University of Florida in 1925 with a perfect record of straight A's as an undergraduate.

While at Iowa, he built a crude, vacuum-tube computing device and showed it to interested persons, including William Mauchly. John was unable to market the device, however, and Mauchly along with John Eckert developed the ENIAC in the 1940's. ENIAC was the first electronic digital computer. It was used from 1946 to 1955. In 1971, the patentability of ENIAC's basic digital concepts was challenged. The Eckert-Mauchly patent was declared invalid in 1973, earning John V.

John William Mauchly Mauchly worked with John Eckert to build the ENIAC and UNIVAC computers. Mauchly got his doctorate in physics before he took a defense electronics course from Eckert in 1941 at the Moore School of Electrical Engineering. Mauchly had an idea to build a computer that was better than the very limited models available at the time. He and Eckert became good friends. They went on to work together to build the ENIAC, which was the first general-purpose electronic digital computer. The two formed their own company and developed the first computer produced for sale in the United States, the UNIVAC.

John Presper Eckert Jr. Eckert, from Pennsylvania, worked with John Mauchly to build the first general-purpose electronic digital computer, called ENIAC. ENIAC stood for Electronic Integrator and Computer. ENIAC was completed after World War II, but it was designed during the war to figure out trajectories for bombs and shells. After the war, ENIAC was used in top-secret projects such as the development of nuclear weapons. ENIAC was quite a bit larger than most modern computers, about 7 feet high and 65 feet long (2.5 X 24 meters). It was 1,000 times faster than the processors that came before it. Following ENIAC, Eckert and Mauchly developed UNIVAC, the Universal Automatic Computer, which was the first computer that people could buy in the United States.

John Williams Mauchly (1907-1980) John Williams Mauchly había nacido en Cincinnati, Ohio (EE.UU.) el 30 de agosto de 1907. Sus magnificas aptitudes como estudiante le valieron una beca para la Escuela de Ingeniería Eléctrica de la Universidad Johns Hopkins. Al cabo de dos años en esta especialidad se dio cuenta que su verdadera vocación no era la ingeniería sino la física. En 1932, a los 35 años de edad, Mauchly se graduó de Doctor en Ciencias Físicas. Luego de doctorarse y pasar un año trabajando en Johns Hopkins, Mauchly pasó a ser el jefe del Departamento de Física en el Ursinus College de Collegeville, Filadelfia, donde se mantuvo desde 1933 hasta 1941. En este año se enroló en el curso de ocho semanas sobre la electrónica aplicada en el campo de la defensa que se dictó en la Universidad de Pennsylvania; allí conoció a Presper Eckert y luego continuó trabajando para dicha Universidad como instructor.

John Atanasoff Who was John Atanasoff? The prototype ... Unveiling the Monument THE PROTOTYPE In the late 1930s, John Atanasoff was still trying to develop ways to facilitate the process of calculating solutions to the extended systems of linear algebraic equations that were applicable to his research work. He became convinced that the digital approach offered considerable advantages over the slower and less accurate analog machines. In December of 1939, working with his graduate student Clifford Berry, John Atanasoff developed and built the prototype of the first electronic digital computer, which would be fully completed in 1942. This prototype of the first computer included four significant and entirely novel operating principles in its operation: The binary system, regenerative data storage, logic circuits as elements of a program, and electronic elements as data carrying media. "After the prototype had started working, we were convinced we could build a computer capable of calculating whatever we would like to", wrote Atanasoff. Having demonstrated the viability of the four major principles, the prototype unequivocally opened the way for all present day computers. In their history of the ENIAC computer, Alice R. Burks and Arthur W. Burks summarize the Atanasoff achievement as follows:

Ames , Iowa The Trial (1 June 1971 to 19 October 1973) The Team. In late 1966 or early 1967, patent lawyer Charles G. Call was summoned to the office of senior partner D. Dennis Allegretti and asked him if he would be interested on taking a case which might take ten years of his time. Call, eager to demonstrate his talents, accepted. Allegretti explained that the client was the Honeywell Company of Minneapolis and the case involved a controversy with the Sperry Rand Corporation over what was called generally "the ENIAC PATENTS." Sperry Rand and its subsidiary corporation, Illinois Scientific Development, Incorporated, had purchased those patent rights from John W. Mauchly and J. Presper Eckert, Jr. Call was somewhat familiar with the earlier litigation involving the ENIAC patents, for that patent challenge had been brought and fought by Bell Telephone Laboratories against Sperry Rand at a time when Call was employed by Bell. U.S. District Judge Archie Dawson had upheld the validity of Sperry Rand's ENIAC patents in his 1962 decision on grounds that Bell Telephone Laboratories had failed to produce sufficient evidence of "prior public use" of ENIAC ideas. It would be an uphill battle for Honeywell to get another court to take any action that would upset Judge Dawson's decision, and Call and Allegretti recognized that point. Allegretti said Honeywell's lawyers had some new evidence that was related to the ENIAC patents and also some antitrust theories for attacking Sperry Rand under the Sherman Act and Clayton Act. It was a tremendous challenge in the face of Judge Dawson's decision for Sperry Rand, but Honeywell lawyers had assured Allegretti that there would be virtually no limitation on the expenditures they could make in following leads that might unearth facts or law to break the ENIAC patents.

75. The First Stored Program Computer -- EDVAC In August 1994, mauchly and Eckert proposed the building of a new machine called the it s creators, john William mauchly and J. Presper Eckert Jr., http://www.maxmon.com/1946ad.htm

1944 AD to 1952 AD The First Stored Program Computer EDVAC As was previously discussed, If we ignore both Atanasoff's machine and COLOSSUS , then the first true general- purpose electronic computer was the ENIAC , which was constructed at the University of Pennsylvania between 1943 and 1946. However, ENIAC's underlying architecture was very different to that of modern computers. During the course of designing ENIAC, it's creators, John William Mauchly and J. Presper Eckert Jr. , conceived the concept of stored program computing. This concept was subsequently documented by Johann (John) von Neumann in his paper which is now known as the First Draft (The computer structure resulting from the criteria presented in the " First Draft " is popularly known as a von Neumann Machine, and virtually all digital computers from that time forward have been based on this architecture.) a In August 1944, Mauchly and Eckert proposed the building of a new machine called the electronic discrete variable automatic computer (EDVAC) . Unfortunately, although the conceptual design for EDVAC was completed by 1946, several key members left the project to pursue their own careers, and the machine did not become fully operational until 1952. When it was finally completed, EDVAC contained approximately 4,000 vacuum tubes and 10,000 crystal diodes. A 1956 report shows that EDVAC's average error-free up-time was approximately 8 hours.

Country: United States Era: 1950 to 1969 John Mauchly grew up in Chevy Chase, Maryland. He went to school in Washington DC where his father was employed as a physicist in the Department of Terrestrial Magnetism at the Carnegie Institute of Technology. In 1925 John was awarded a scholarship by the State of Maryland to allow him to attend Johns Hopkins University in Baltimore, Maryland. He began studying engineering at Johns Hopkins but his interests changed in the course of his studies towards pure science and his first degree was in physics. Mauchly continued studying physics after taking his first degree and he was awarded his doctorate in 1932. He then taught physics at a number of different colleges and spent some time at the Carnegie Institution in Washington DC undertaking research on analysing the weather. By 1940, Mauchly was teaching physics at Ursinus College near Philadelphia. While there he became interested in developing electronic computers which combined his interests in physics and engineering. It may seem strange today that someone with an interest in engineering would be drawn towards building computers, but at this time a computer was a huge mechanical construction. Also, Mauchly's interests were in electrical engineering and he looked for ways to develop electrical circuits for computation.

80. Vonneumann's First Computer Program when john mauchly of Philadelphia and a colleague, J. Presper Eckert, Although mauchly, Eckert, and Von Neumann all contributed to its success, http://www.amphilsoc.org/library/exhibits/treasures/vonneuma.htm

The first stored program for a computer Over the past decade, the popular press has periodically announced that as the atomic age has passed and the information ages dawned, the a-bomb has been replaced in our hearts and minds by the computer. In a remarkable feat of synchronicity, these two technological achievements , icons of modernity, were developed at nearly the same time, and for nearly the same reasons. Research and development of a practical electromechanical calculator was being carried out at a number of American laboratories by 1942, when John Mauchly of Philadelphia and a colleague, J. Presper Eckert, drew up a technical outline of a machine intended to perform the laborious calculations needed to calculate the trajectories of artillery shells and submitted it to the Ballistic Research Laboratory (BRL) of the Army. The government soon devoted its resources to developing what would become the computer, and organized a project supervised by J.G. Brained and appointing Lt. Herman H. Goldstine as technical liason for the BRL. The fruits of this first essay into modern computing was the Electronic Numerical Integrator and Computer (ENIAC), which was dedicated on February 15, 1946. Weighing in at over 30 tons, 150 feet in length, and consuming over 19,000 vacuum tubes, ENIAC was a giant, faster than any previous computer, able to perform fourteen 10-digit multiplications in a mere second - 500 times faster than the best mechanical calculators of the day. Despite its speed, however, it was hampered by highly limited in its internal memory and the need to rewire the computer manually for each separate program it was to run. Mauchly and Eckert had adopted such an inflexible design for ENIAC as a matter of expediency, given the demands of the wartime military, but they recognized that the inefficiency could be lessened by adopting serial calculation rather than parallel, and thus a new project, the Electronic Discrete Variable Computer (EDVAC) was born. Enter John Von Neumann.
