Dr. Veblen listened for a short period of time before cutting off Goldstine. John Mauchly died on January 8 1980, in Ambler, Pennsylvania. Thanks to the Collections of the University of Pennsylvania Archives. He subsequently transferred to the Physics Department, and without completing his undergraduate degree, instead earned a Ph.D. in physics in 1932.

The biggest challenge facing Mauchly and Eckert was devising a means to control the circuits responsible for counting the electronic pulses. One malfunction had the potential to throw off ENIAC's entire calculation, and Eckert and Mauchly worked tirelessly to guard against potential kinks in the system. These units had the capacity both to store numbers and to combine them.

The machine was less accurate than a digital, or electronic, machine would have been because the solutions it provided were estimates. John William Mauchly (August 30, 1907 – January 8, 1980) was an American physicist who, along with J. Presper Eckert, designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States. Dr. Veblen listened for a short period of time before cutting off Goldstine. As soon as you start to attempt to answer the question of who invented the first computer you start to realize the question itself has little meaning. But it worked. 17 34 ENIAC, patent interference, correspondence and documents relating to, 1954. The Franklin Institute acknowledged their work with the Potts Medal in 1949, and the American Federation of Information Processing Societies with the Harry Goode Medal in 1966. Mauchly consistently maintained that it was the use of high-speed electronic flip-flops in cosmic-ray counting devices at Swarthmore College that gave him the idea for computing at electronic speeds. Some of the elements that led up to Eckert and Mauchly's work are described in other articles - Shannon's idea to base computers on binary arithmetic and later Von Neumann's invention of the stored program computer. When army gunners aimed their artillery guns, they relied on a booklet of firing tables to aim properly. The problem was that the heating filament consumed lots of electrical power, generated lots of heat and burned out at regular intervals. Philadelphia, PA 19103, The Franklin Institute Eckert's decade counter provided the crucial technology for turning pulses into numbers. Mauchly was principal consultant for the ENIAC project, and J. Presper Eckert, Jr., the man who became Mauchly's close associate, was chief engineer. The design of ENIAC was based on this notion, and ENIAC's final design was decentralized, meaning that its computing power was spread throughout many units. They tried to find a buyer for their planned machine and for the second time in the history of computing the US Census Bureau fitted the bill. It was roughly a thousand times faster than the existing technology. Univac was the first commercial computer in the US (LEO 1 was produced commercially in the UK in the same year) and, proving the pessimists wrong, various companies immediately ordered a total of 50. Mauchly's scheme to create an electronic calculator that would take the place of all the "computers" made its way to Goldstine, who immediately recognized the ingeniousness of Mauchly's proposal. The trouble is that it took at least one vacuum tube per logic gate and two for each unit of storage. Eckert and Mauchly eventually ran into financial troubles, and in 1950 they sold their company along with their computer patents to Remington Rand.
