Sie stehen für die Anfänge des Computers im Spannungsfeld der durch den Zweiten Weltkrieg ausgelösten Technologieoffensive in den USA. So erklärte sich schon im Jahr 1939 die US-Navy bereit, Aikens Projekt zum Bau des Automatic Sequence Controlled Calculators (ASCC - später Harvard Mark I) mit Hilfe der IBM in die Tat umzusetzen. 1943 war diese Maschine betriebsfähig. In diesem Jahr drangen Eckert und Mauchly mit ihrem Vorschlag bei der US-Army durch, einen elektronischen Computer mit bis dahin ungekannter Rechengeschwindigkeit zu bauen, den Electronic Numerical Integrator and Computer - ENIAC. Howard H. Aiken sah sich in der Nachfolge von Charles Babbage. Es gelang ihm, gemeinsam mit den Entwicklungsingenieuren der IBM eine elektromechanische, programmgesteuerte Großrechenmaschine zu realisieren. Bis zum Jahr 1956 berechnete "Bessie" im Computation Laboratory der Universität von Harvard Tafelwerke mathematischer Funktionen. Eckert und Mauchly lernten sich an der Moore School of Electronics der Universität von Pennsylvania in Philadelphia kennen.

Extractions: These three American computer pioneers symbolize the dawn of the Computer Age. Their machines were the first automatic calculators that captured the imagination of the general public. Howard H. Aiken John W. Mauchly and J. Presper Eckert developed the ENIAC, the world's first electronic large-scale general-purpose digital automatic calculator, at the University of Pennsylvania. It was fully operational in 1946. The two inventors were convinced that computers could bring benefits beyond the area of scientific and military applications. They set up their own business to develop the UNIVAC (Universal Automatic Computer). Due to financial difficulties, Mauchly and Eckert had to sell their company to Remington Rand in 1950 but remained in charge of the development of UNIVAC. On presidential election night in 1952, UNIVAC, on the basis of only 3,398,745 votes in, predicted a landslide victory for Eisenhower - in complete contrast to opinion polls that had predicted a close race. But UNIVAC was right! After this election night on television, UNIVAC rapidly became the generic name of a computer in the USA.

Extractions: J. Presper Eckert was co-inventor of ENIAC, introduced to the public at the University of Pennsylvania in 1946. ENIAC was considered a computer marvel, containing over 17,000 vacuum tubes and weighing over 30 tons. Although ENIAC was not the first computer, it was the first electronic device designed to carry out general-purpose computation. It could add, subtract, multiply, divide, and extract square roots, as well as predict weather, calculate atomic energy, study cosmic rays and examine wind tunnel design. ENIAC, housed at the Moore School of Electrical Engineering, was 1,000 times faster than previous electromechanical calculators.

Extractions: ENIAC 1996: Celebrating the birth of modern computing By Peter C. Patton In 1776 a group of patriots met in a tavern at Fourth and Walnut Streets in Philadelphia to plan a revolution that changed the world. In 1942 a group of Penn electrical engineering faculty and graduate students met at Linton's Restaurant at Thirty-third and Chestnut Streets to discuss the feasibility of electronic digital computing. On St. Valentine's Day, 1946 they demonstrated the first working electronic digital computerstarting a technological revolution as profound as the political one nearly two centuries before. In 1996 Penn and Philadelphia will mark the 50th anniversary of this eventthe birth of modern computingwith 18 months of programs and celebrations. Forerunners There had been earlier attempts to build machines that did computing. Charles Babbage had designed a general-purpose mechanical digital computer in the 1700s, and his colleague Countess Ada Lovelace had proposed means for "programming" it, much as a Jacquard loom is controlled to create woven patterns. Mechanical analog computing had been developed by Vannevar Bush at MIT in the 1930s. In 1939 Howard Aiken, a mathematics professor, had built an electromechanical digital computer, the Harvard-IBM Sequence Controlled Calculator, designed to compute tables of mathematical functions like sines, cosines, and Bessel functions. Such machines relied on moving mechanical parts to perform calculations, limiting the potential compactness, speed, and reliability of these devices.

http://www.scl.ameslab.gov/ABC/Articles/Future.html

Extractions: (Commentary aired on WOI Radio on July 14, 1995) The story of John Vincent Atanasoff has become an Iowa legenda legend that's still unfolding. The basic outlines of the tale are familiar. A bright young physics professor pursuing forefront research during the depths of the depression found the theoretical calculations extraordinarily tedious, using the desk top adding machines and calculators of the day. He became obsessed with the idea of automating such calculations using some combination of electrical and mechanical devices. After researching and pondering this problem to no avail, he hit upon a scheme for such an automatic computing device during a long wandering trip across the Iowa countryside, scribbled down his plan in an Illinois road house, and returned to Ames to embark on the construction of the first electronic digital computer. With help from a bright graduate student, and an expenditure of less that $1,000, an amount close to half of a young professor's salary in those depression years, the device was designed, redesigned, constructed, tested, and it worked. This achievement was little noted at the time, and after Atanasoff left Iowa State College for the Naval Ordnance Laboratory in 1941, the machine was consigned to oblivion in the Physics Building on campus. For a long time there was also little likelihood that this achievement would be long remembered. The fundamental ideas were pirated away, used as building blocks in the design of subsequent computers during and after World War II, and machines based on Atanasoff's concepts now from part of the bedrock of today's information revolution. The initial credit for inventing the electronic computer went to the purported pirate, John W. Mauchly, who died in 1980, and to J. Presper Eckert, who used the ideas in a wartime device built for computing artillery trajectories, (called ENIAC), which led eventually to UNIVAC.

Preferred Citation: Honeywell, Inc., Honeywell vs. Sperry Rand Records (CBI 1), Charles Babbage Institute, University of Minnesota, Minneapolis. 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.

Extractions: and J. Presper Eckert (American 1919-1995) Americas 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. 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.

Extractions: The History of the Computer Eckert and Mauchly John W. Mauchly and J. Presper Eckert were the builders of ENIAC, a very significant step in the history of computing. At the Moore School of the University of Pennsylvania, the two received military funding to work on the computer which Mauchly had envisioned. His vision, coupled with Eckert's superior engineering ability, enabled the ENIAC to be completed in a timely fashion. A dispute arose, however, when the two tried to patent their invention. This dispute eventually led to the resignation of the two visionaries, who in turn founded a new company, the Eckert - Mauchly Computer Corporation (EMCC). Eckert took to designing new computer hardware, while Mauchly sought business applications by which they could market their completed product. The first contract for EMCC was the U.S. Census bureau. The census was prefectly suited to the new computers due to the massive amount of information to process and the time restraints involved. In 1948, Prudential Insurance became the first private contract for EMCC, using ENIAC for calculating life expectency tables. Eckert and Mauchly vastly underestimated the cost in both money and time to produce a complex computer system, and in 1950 were forced to sell the company lest it go under. The purchaser was Remington-Rand, formerly the main competitor of EMCC.

Extractions: die Unisys Wurzeln bis Remington zurückreichen. Die erste Schreibmaschine wurde bereits in den 70iger Jahren des vorletzten Jahrhunderts (1873) entwickelt. Das änderte den Umgang mit Informationen grundsätzlich. American Arithmometer auch ein Vorgänger von Unisys war. Die erste kommerziell nutzbare mechanische Addier- und Rechenmaschine wurde 1886 entwickelt. Bis 1926 wurden mehr als eine Million Maschinen geliefert und somit der "mechanische Computer" (der PC der 20-iger Jahre) geschaffen. Unisys bzw. Sperry auf eine große Anzahl von Entwicklungen auf dem Gebiet der Gyroskop-, Navigations- und Steuerungstechnologien (1910) zurückblicken kann. Dadurch verbesserte sich die Art, wie diese speziellen Informationen für Schifffahrt- und Luftfahrtnavigation, Handel und Militär verwendet wurden. Unisys Wurzeln auch bei Rand zu finden sind. Rand entwickelte die ersten modernen Ablage- und Indexsysteme. Informationen werden seither auf neue Art und Weise organisiert, abgelegt und abgefragt.
