These giant computers, which used thousands of vacuum tubes for computation, were the forerunners of today’s digital computers. A mechanical digital calculating machine was built in France in 1642, but a 19th century Englishman, Charles Babbage, is credited with devising most of the principles on which modern computers are based. It was designed principally by J. Presper Eckert and John Mauchly,[1,2] the inventors of the first general-purpose electronic computer, the ENIAC. Betsy Ross.

Who invented the first Programmable Computer and where? The political situation in California was tense in 1846. UNIVAC was, effectively, an updated version of ENIAC. Even so, this machine still got a great amount of publicity from being able to do the work of many people in a short span of time. Mathematician Grace Hopper completes A-0, a program that allows a computer user to use English-like words instead of numbers to give the computer instructions. Forty-six UNIVAC computers were built for both government and business uses. CSCA0101 Computing Basics 24 History of Computers The UNIVAC, or universal automatic computer, was invented by Eckert and Mauchly, inventors of the ENIAC.The UNIVAC was a general-purpose computer using Von-Neumann’s concept of stored program (we’re all kind of used to that today), with IO devices including magnetic tape in addition to the standard punch card, a printer, and a typewriter with standard typewriter keyboard. The ERA 1101 was publicly announced in December 1951. Forty-six UNIVAC computers were built for both government and business uses. He invented a way to record data to control the weaving patterns of loom using a big loop of paper with precisely punched holes. The search for mechanical devices to aid computation began in ancient times. Remington Rand eventually sold 46 Univac 1s at more than $1 million each. The abacus, developed in various forms by the Babylonians, Chinese, and Romans, was by definition the first digital computer because it calculated values by using digits.

UNIVAC I was soon used to tabulate part of the 1950 population census and the entire 1954 economic census. When the truth was revealed, it was considered amazing that a computer could do what political forecasters could not, and the UNIVAC quickly became a household name. On March 31, 1951, the Census Bureau accepted delivery of the first UNIVAC computer. Mary Bellis covered inventions and inventors for ThoughtCo for 18 years. These were, in turn, supplanted by the integrated-circuit machines of the mid-1960s and 1970s. ENIAC (which meant "Electronic Numerical Integrator And Computer") was a computer built between 1943 and 1946. Remington Rand's lawyers unsuccessfully tried to re-negotiate the government contract for additional money. Later in 1950, the ERA 1101 or UNIVAC 1101 was the first computer to store and execute a program from memory and delivered to the United States government for the first time. With further improvements by other inventors, these semi-automated looms sold very modestly. The computer had correctly predicted that Eisenhower would win, but the news media decided to blackout the computer's prediction and declared that the UNIVAC had been stumped. In 1950, Eckert and Mauchly were bailed out of financial trouble by Remington Rand Inc. (manufacturers of electric razors), and the "Eckert-Mauchly Computer Corporation" became the "Univac Division of Remington Rand." Sept. 1947...developed by Bell Labs. On June 14, 1951 the very first electronic computer produced in series (and in the United States), the UNIVAC I (Universal Automatic Computer) was delivered to the US States Census Bureau at the price of $1.6 Mio. John Presper Eckert and John Mauchly, after leaving the academic environment of The Moore School of Engineering to start their own computer business, found their first client was the United States Census Bureau. EDVAC was one among the earliest electronic computers invented. The UNIVAC was used to calculate company payrolls, sales records, analysis of sales performance and other company business.

A single IC chip may contain thousands of transistors. When was the first personal computer invented? The sponsor was the U.S. Army Ordnance Department, which wanted a better way of calculating artillery firing tables, and the work was done at the University of Pennsylvania. By the 1920s, companies such as the International Business Machines Corporation (IBM) were supplying governments and businesses with complex punch-card tabulating systems, but these mechanical devices had only a fraction of the calculating power of the first electronic digital computer, the Atanasoff-Berry Computer (ABC).

UNIVAC tapes were ½" wide, 0.0015" thick, up to 1,500' long, and made of phosphor-bronze with a metallic coating. UNIVAC and other first-generation computers were replaced by transistor computers of the late 1950s, which were smaller, used less power, and could perform nearly a thousand times more operations per second.
