WHO NEEDS PERSONAL COMPUTERS? by J. Presper Eckert J. Presper Eckert was the chief engineer on ENIAC I. He is currently vice-president and technical assistant to the president of Sperry Computer Company. I must confess that I don't own a personal computer. I have no reason to. I suppose I could use a computer for my hobby, electronic musical instruments, and conduct research on how to generate an accurate replica of a piano note (today's electronic pianos lack warmth in their tones). But I would need a pretty fast computer to handle the sampling of a note's characteristics in a reasonable amount of time. I may just wait for the next generation of personal computers based on the 32-bit microprocessors now appearing from a number of manufacturers. We've come a long way since the day when Dr. Howard Aiken, designer of the pioneering Mark series of computers at Harvard, could say that just a half-dozen electronic machines would be enough to fulfill the world's computational needs (a statement he later retracted). On the other hand, I remember my late colleague John Mauchly talking about the importance of personal computers long before they existed. During the late 1950s I was involved in trying to build what could now be called a personal computer, probably the first such machine to fit on a desktop. We used hundreds of magnetic core amplifiers and diodes, a few transistors and tubes, and a motor-driven drum for memory storage. The same motor powered a flyprinter, which typed the computer's output onto a moving strip of paper. Unlike the first microcomputer systems, which came later, our machine included a keyboard for easy input. We figured we could sell our Desk Computer for $5,000. Some insurance firms expressed interest, but our executives just couldn't see business need for that small a computer.

Professor Wallace J. Eckert First Automated Scientific Calculations First Scientifc Computing Lab First Computer Book Naval Observatory ... Apollo Missions Photo: About 1930, Columbiana Archive. Wallace Eckert , 1902-1971. With graduate study at Columbia, the University of Chicago, and Yale, he received his Ph.D. from Yale in 1931 under Professor Ernest William Brown (1866-1938), who devoted his career to developing a theory of the motions of the moon. Best known for the lunar orbit calculations that guided the Apollo missions to the moon , Eckert was a Columbia University Astronomy Professor from 1926 to 1970, founder and Director of the Thomas J. Watson Astronomical Computing Bureau at Columbia University (1937-40), Director of the US Naval Observatory Nautical Almanac Office (1940-45), and founder and Director of the Watson Scientific Computing Laboratory at Columbia University (1945-1966). First, foremost, and always an astronomer, Eckert drove and often oversaw the construction of increasingly powerful computing machines to solve problems in celestial mechanics, particularly to verifying, extending, and improving Brown's theory. He was one of the first to apply punched-card machines to the solution of complex scientific problems. Perhaps more significantly, he was the first to automate the process when

Programming the ENIAC Built in 1943-45 at the Moore School of the University of Pennsylvania for the War effort by John Mauchly and J. Presper Eckert (no relation to Columbia University's Wallace Eckert ) but not delivered to the Army until just after the end of the war, the Electronic Numerical Integrator And Computer (ENIAC) was the first general-purpose electronic digital computer. It was 150 feet wide with 20 banks of flashing lights and about 300 times faster than the Mark 1 at addition. Wallace Eckert is cited in the histories as an influence on the designers, as he was for the Mark 1. These US Army photos from the archives of the ARL Technical Library show two early programmers (Gloria Gorden and Ester Gerston) at work on the ENIAC. The ENIAC was not a stored-program computer. It was programmed by a combination of plugboard wiring (shown at the top) and three "portable function tables", shown above ( CLICK HERE and HERE for better views). Each function table has 1200 ten-way switches, used for entering tables of numbers. Note the IBM punches on the far right a bit hard to make out; better visible in this clearer but less atmospheric copy of the same photo .

Fascinating facts about the invention of the ENIAC Computer by John Mauchley and J. Presper Eckert in ENIAC COMPUTER In 1936 British mathematician Alan Turing proposed the idea of a machine that could process equations without human direction. The machine (now known as a Turing machine) resembled an automatic typewriter that used symbols for math and logic instead of letters. Turing intended the device to be used as a "universal machine" that could be programmed to duplicate the function of any other existing machine. Turing's machine was the theoretical precursor to the modern digital computer. In the 1930s American mathematician Howard Aiken developed the Mark I calculating machine, which was built by IBM. This electronic calculating machine used relays and electromagnetic components to replace mechanical components. In later machines, Aiken used vacuum tubes and solid state transistors (tiny electrical switches) to manipulate the binary numbers. Aiken also introduced computers to universities by establishing the first computer science program at Harvard University. Aiken never trusted the concept of storing a program within the computer. Instead his computer had to read instructions from punched cards. John Mauchley, an American physicist, and J. Presper Eckert, an American engineer, proposed an electronic digital computer, called the Electronic Numerical Integrator And Computer (ENIAC), which was built at the Moore School of Engineering at the University of Pennsylvania in Philadelphia. The computer was based on some concepts developed by John Atanasoff, a physics teacher at Iowa State College. ENIAC was completed in 1945 and is regarded as the first successful, general digital computer.

Preferred Citation: Honeywell, Inc., Honeywell vs. Sperry Rand Records (CBI 1), Charles Babbage Institute, University of Minnesota, Minneapolis. Historical Note The Honeywell-Sperry Rand suit grew out of the ENIAC patent, which covered basic patents relating to the design of electronic digital computers. After the patent was granted to the Sperry Rand Corporation in 1964, the corporation demanded royalties from all major participants in the computer industry. Honeywell refused to cooperate, so Sperry Rand then filed a patent infringement suit against Honeywell in 1967. Honeywell responded in the same year with an antitrust suit charging that the Sperry Rand-IBM cross-licensing agreement was a conspiracy to monopolize the computer industry, and also that the ENIAC patent was fraudulently procured and invalid. Honeywell filed suit against Sperry Rand and its subsidiary, Illinois Scientific Instruments, Inc., in U.S. District Court (Minnesota District, 4th Div., No. 4-67-Civ. 138). The ENIAC patents were filed in 1947 by John W. Mauchly and J. Presper Eckert, arising from the work conducted at the Moore School of Electrical Engineering at the University of Pennsylvania.  In 1946, Eckert and Mauchly left the Moore School and formed their own commercial computer enterprise, the Electronic Control Company, which was later incorporated as the Eckert-Mauchly Computer Corporation. In 1950 Remington Rand acquired Eckert-Mauchly.  The rights to the ENIAC patent eventually passed to Sperry Rand as a result of a merger of the Sperry Corporation and Remington Rand in 1955.

NCERD IT Timeline A Short Biography of John Mauchly (American 1907-1980) and J. Presper Eckert (American 1919-1995) ENIAC America’s first completely electronic computer was designed by the engineer John Mauchly and a graduate student called J. Presper Eckert. The ENIAC (Electrical Numerical Integrator and Calculator) weighed 50 tonnes and occupied 2000 sq. ft. It contained 18000 vacuum tubes and several kilometers of electrical wire. It could store about 20 words in its memory. At a press conference at the University of Pennsylvania in 1946 it was announced that ENIAC could multiply a 5-digit number by itself 5000 times in half a second. ENIAC ENIAC was designed to calculate ballistic trajectories. One of the first test runs was the “Manhatten Project” to help create the first atomic bombs which were dropped on Hiroshima and Nagasaki. EDVAC Eckert and Mauchley's Electronic Discrete Variable Automatic Computer (EDVAC) was completed in 1950 and was the first to use magnetic disks for storage. Eckert and Mauchly were better at computer design than they were at the economics of running a company. 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.

J. Presper Eckert Eckert was a grad student studying at the Moore School in 1943. There, he met John Mauchly, who spoke about the idea of an electronic version of the Ganged Calculator. Mauchley needed someone to oversee the design and construction of the ENIAC, and it was J. Presper Eckert who rose to the challenge. Because vacuum tubes were well-known to burn out without warning, one of the largest engineering challenges facing the ENIAC team was how to make the tubes more reliable. Eckert's design addressed this problem in three ways. First, he designed the circuits of the ENIAC so that the tubes only needed to represent "on" or "off" instead of any numerical value. This design feature meant that even if a tube varied from its specification, it would still be correct in terms of being on or off. Second, the tubes themselves led "pampered" lives, for vacuum tubes. Eckert knew that tubes usually fail early or late in their lives, so he made sure the ENIAC used only tubes drawn from a special 'burnt-in" selection. These were tubes that had been running long enough to be known to be good, but still young enough to have many useful hours left. Also, the circuits were only energized with about one quarter of the normal voltage for the tubes. This way, the tubes ran much cooler and thus lasted longer. Third, Eckert designed the ENIAC using a "component" system. By organizing the parts into discreet components, Eckert simplified the tasks of maintenance and troubleshooting. Whenever there was a problem, it was a simple matter to replace the broken component.
