John presper eckert invention

In Mauchly drafted a memo outlining the first large-scale digital electronic computer designed for general numerical computations. An official proposal was submitted in April ofand the U. Mauchly, who was responsible for much of the overall design, is said to have been influenced by the work of Iowa State College professor John V. Atanasoff, who had designed and built an electronic computing device between and with a graduate student, Clifford Berry.

He overcame many difficult technical challenges before he succeeded. Unknown to many, these six women wrote and tested the programs for the ENIAC and without their work, the project may not have been completed. Government asked women to fill-in with positions typically given to men. This is how the women were hired by the U. The hour-long calculations they performed by hand would only take a computer mere seconds today.

Though it had been funded as a technology that might help the war effort, the war was over by that time. In the process of the trial the source of John Mauchly's ideas for the electronic devices was in question. Honeywell supported the claim that Mauchly had acquired the basic concepts from John Vincent Atanasoff during a visit to the latter's home in Iowa.

Atanasoff and Clifford Berry. Berkeley, Edmund C. Burks, A. Eckert, J. Evans, Christopher, "J. Mauchly, John W. Maynard, M. Presper, " in Ralston, Anthony, and Edwin D. Reilly, Jr. Presper, Jr. Mauchly, Herman H. Goldstine, and J. All rights reserved. A year later, soon after ENIAC was dedicated to the public, the Moore School clarified its patent policy and now insisted that any future patent rights of researchers had to come to the university.

By this time, with the war over, Eckert and Mauchly were already considering other career possibilities, and the new policy became a determining factor. They both refused to sign and resigned from the university. While both had several job possibilities, they decided they should take a bold step. In Marchthey established the Electronic Control Company, the first commercial computer company in the United States.

The application was finally filed on 26 Junebut the patent, U. Patent 3,, was not finally granted until 4 February At that time, the rights were owned by Sperry Rand, where Eckert then worked. When the company began trying to collect royalties on the patent, some firms, such as International Business Machines IBMreached negotiated settlements.

Honeywell Corporation, in contrast, decided to challenge the patent, and filed suit in A trial finally began inand ran until 13 March In a dramatic conclusion, Judge Earl R. While he noted many findings, he gave two primary reasons. First he concluded that Mauchly had not conceived his idea independently, but had derived it from knowledge of the work of John V.

Atanasoff at Iowa State University. Atanasoff had developed an electronic computing device in the late s, and Mauchly had visited him for four days in June Although Mauchly argued that this interaction was not the source of his idea, the judge ruled against him. The judge also concluded that there had been substantial public disclosure before the patent was filed.

Creating a Computer Company. In the postwar period, there was little venture capital available to finance start-up companies, and no established market for digital computers. When creating their computer company, Eckert and Mauchly had to start small and continually struggle to finance company operations. Their first customer was the. Army Ordnance Department to develop a computer.

The expectation was that the project could develop into a larger contract for a full computer. In Decemberthe two incorporated their company and renamed it the Eckert-Mauchly Computer Company. Funding from the Census Bureau would not keep them afloat, especially as they added employees, so they continually sought new customers. It was not fully a success, however, as it was delivered more than a year late.

Northrop was never able to run the computer reliably once it had been transferred to them. Again, development took longer than expected. Because of delays and cost escalation, Prudential and Nielsen ultimately canceled their contracts. However, other government agencies and private companies bought machines. The most famous was serial number 5, which was sold to the Atomic Energy Commission and installed at the University of California Radiation Laboratory.

In the CBS john presper eckert invention network used it to predict the outcome of the presidential election between Adlai Stevenson and Dwight Eisenhower. On election night, with only 3. The prediction was so lopsided that CBS decided not to air it, but the computer turned out to be close. Eisenhower won by thirty-nine states to nine, with a total of He was there whenever anyone else was, working on the nagging problems of the moment.

Although Eckert and Mauchly had produced the first successful business computer in the United States, they were not themselves successful businessmen. They grossly underestimated both the cost of developing their products and the time required.

Their company remained in financial difficulty. The problem was finally solved when the Remington Rand Company, a major producer of office equipment, bought the Eckert-Mauchly Computer Company on 1 February In Remington Rand also acquired Engineering Research Associates, another fledgling computer company, and thus became one of the leading computer companies in the United States.

Other mergers would follow. In the mids, it seemed that Remington Rand was poised to take the lead in the new business of computer development, but the company was unable to turn a profit with computers. Not until the early s did the computer division make money, and by that time, Remington Rand was being overshadowed in the market by rival IBM.

In contrast, other firms that entered the business in the s gave up after years of major losses. Mauchly left Remington Rand in to form a consulting firm, Mauchly Associates. Eckert, however, stayed with the company. He served as director of engineering, —; vice president and director of commercial engineering, —; vice president and executive assistant to the general manager, —; and vice president and technical advisor to the president, — Eckert published few technical papers during his career.

In the article he summarized the range of memory devices then being used or explored for use in computer systems. They ranged from vacuum tubes, such as were employed in ENIAC, to ferromagnetic cells, which would form the foundation of magnetic core memories. Eckert gave special attention to delay-line memories, which he had personally pioneered.

The article makes clear, however, that he knew other techniques would soon surpass what could be done with delay-line systems. He was issued ninety during his career: twenty-nine to him personally, ten jointly with Mauchly, and fifty-one jointly with other inventors. The topics ranged from electronic circuits, to memory systems, to printers.

Patent 2,, for example, was the first patent Eckert and Mauchly received on the ideas inherent in the mercury delay memory system. Clearly Eckert saw patents as more important to his legacy as an engineer than publications. Eckert was elected to the National Academy of Engineering in He fully retired inand died of leukemia in Inafter noting the remarkable progress in computer development over four decades, he penned his own wry epitaph.
