  J. Presper Eckert - Wikipedia, the free encyclopedia
John Presper Eckert, a computer pioneer, was born April 9, 1919 in Philadelphia and died June 3, 1995 in Bryn Mawr, Pennsylvania.
Mauchly and Eckert among others who also devised the stored-program concept when they understood the limitations of ENIAC.
In 1950, Eckert-Mauchly Computer Corporation ran into financial troubles and was acquired by Remington Rand Corporation.

 ENIAC - Wikipedia, the free encyclopedia
The computer was commissioned on May 17, 1943 as Project PX, constructed at the Moore School of Electrical Engineering from mid-1944, and formally operational from February 1946 having cost almost $500,000.
The idea of the stored-program computer came during the development of the ENIAC, but it was not implemented because (1) the machine was to be completed quickly so that it could aid in the war effort, and (2) it was realized that 20 storage locations for memory and programs would be much too small.
Eckert and Mauchly took the experience they gained and founded the Eckert-Mauchly Computer Corporation, producing their first computer, BINAC, in 1949 before being acquired by Remington Rand in 1950 and renamed as their UNIVAC division.

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 1937 and 1942 with a graduate student, Clifford Berry.
Mauchly and Eckert resigned from the Moore School shortly after the public announcement of the ENIAC and formed the Electronic Controls Company.
Eckert and Mauchly were recognized with numerous honors and awards for their work, having both received the U.S. National Medal of Science in 1969 and the IEEE Computer Society Pioneer Award in 1980.

Eckert and Mauchley's Electronic Discrete Variable Automatic Computer (EDVAC) was completed in 1950 and was the first to use magnetic disks for storage.
Their company, the Eckert-Mauchly Computer Corporation soon hit financial difficulties, the main problem being that this was such a new area that costs of production were extremely hard to estimate.
Mauchly left Remington Rand and formed Mauchly Associates of which he was president from 1959 to 1965 when he became chairman of the board.

 ENIAC
ENIAC, short for Electronic Numerical Integrator And Computer, was the first all-electronic computer designed to be Turing-complete, capable of being reprogrammed by rewiring to solve a full range of computing problems.
It was preceded in 1941 by the fully tape-programmable but still mechanical Z3 designed by Konrad Zuse and by the all-electronic rewire to reprogram but not fully general purpose British Colossus computer.
The freeze on design in 1943 meant that the computer had a number of short-comings which were not solved, notably the inability to store a program.

Eckert assumed the task of designing a new computer system, more or less along the lines laid out in von Neumann's report.
Mauchly, meanwhile, took on the more general task of identifying the uses of electronic computers.
Mauchly recognized that the decennial census was but four years away and reasoned that he could sell a computer to the Census Bureau as a way of reducing its costs for tabulating its immense volume of data.

Although Mauchly and Eckert could produce an experimental machine in the confines of a laboratory, a standard commercial system run by trained operators rather than research engineers required further improvements in design and reliability.
Ultimately it was the cost of developing a commercial computer that led Eckert and Mauchly sold their company to Remington Rand in February of 1950.
In this connection, EMCC had developed a digital magnetic tape recording unit that could deliver data to the UNIVAC at a rate of 40,000 binary digits (bits) per second.

Eckert then set me to work to design the crystal transducer system for the acoustic memories of the UNIVAC and then all of the electronics for the memory system.
Eckert, who had been my mentor, said to me when I left: "You may never build another computer again, but it is probably true that everything you build in the future will in one way or another resemble a computer." He was right.
Bear in mind that with Eckert's $100,000 engineering goal (even if that translates to $500,000 today) he intended to design from scratch the world's first commercial computer, the world's first card-to-tape converter, the world's first commercial acoustic memories, etc. Keep in mind that there was typically a half to one engineer working on each subsystem.

After USNR Midshipman's School-W, she was assigned to the Bureau of Ordnance Computation Project at Harvard University, where she worked at Harvard's Cruft Laboratories on the Mark series of computers.
The key to opening up new worlds to computing, she knew, was the development and refinement of programming languages - languages that could be understood and used by people who were neither mathematicians nor computer experts.
Pursuing her belief that computer programs could be written in English, Admiral hopper moved forward with the development for Univac of the B-O compiler, later known as FLOW-MATIC.

These cards were sold at the main office of the Andrew R. Jennings Computing Center of the Case Institute of Technology, and a generation punched their first programs onto them, usually written in Algol for the Case UNIVAC 1107.
In 1967, Case Institute of Technology shut down the 1107 and spun off its main computing facility as a private "computing utility" (a buzz word of the time bearing the same cachet "Internet Commerce Server" has at this writing) which provided the university computing services as its "base load customer".
