who invented the computer?

Answer 1

Charles Babbage was the first to conceptualize and design a fully programmable computer as early as 1820, but due to a combination of the limits of the technology of the time, limited finance, and an inability to resist tinkering with his design, the device was never actually constructed in his lifetime. By the end of the 19th century a number of technologies that would later prove useful in computing had appeared, such as the punch card and the vacuum tube, and large-scale automated data processing using punch cards was performed by tabulating machines designed by Hermann Hollerith.

but the very first computers were inverted in Greece Examples of these early devices, the ancestors of the computer, included the abacus and the Antikythera mechanism, an ancient Greek device for calculating the movements of planets which dates from about 87 BC.[1] The end of the Middle Ages saw a reinvigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers.[2]

Answer 2

The Atanasoff-Berry Computer was the world's first electronic digital computer. It was built by John Vincent Atanasoff and Clifford Berry at Iowa State University during 1937-42. It incorporated several major innovations in computing including the use of binary arithmetic, regenerative memory, parallel processing, and separation of memory and computing functions.

On October 19, 1973, US Federal Judge Earl R. Larson signed his decision following a lengthy court trial which declared the ENIAC patent of Mauchly and Eckert invalid and named Atanasoff the inventor of the electronic digital computer -- the Atanasoff-Berry Computer or the ABC.
Clark Mollenhoff in his book, Atanasoff, Forgotten Father of the Computer, details the design and construction of the Atanasoff-Berry Computer with emphasis on the relationships of the individuals. Alice and Arthur Burks in their book, The First Electronic Computer: The Atanasoff Story, describe the design and construction of the ABC and provide a more technical perspective. Numerous articles provide additional information. In recognition of his achievement, Atanasoff was awarded the National Medal of Technology by President George Bush at the White house on November 13, 1990.

Answer 3

Supposing you mean "who invented the electronic computer", there are at least six different answers.

John V. Atanasoff and Clifford Berry constructed an electronic machine "ABC" which contained a binary adding circuit, at Iowa State College in 1939. This was important - see below.

Max Newman and Tommy Flowers invented the Colossus calculating machine in 1943, to help break German codes at Bletchley park in England. It contained 1500 electronic valves. It is often supposed that Alan Turing helped with this invention, but there are contradictory accounts.

J. Presper Eckert and John W. Mauchly built the ENIAC calculator at the Moore School of Electrical Engineering in Pennsylvania in 1944-45 to work out artillery firing tables. It had 18,000 electronic valves. When they tried to use its invention to apply for a patent on electronic computing, the judge threw it out, citing John V. Atanasoff's invention as "prior art".

John von Neumann of the Princeton Institute of Advanced Study, together with A.W. Burks and H.H. Goldstein, wrote an incredibly important paper "Preliminary discussion of the logical design of an electronic computing instrument" in 1946. It laid down the design of proper computers, building on the ideas in Colossus and ENIAC, and was pretty strictly followed for a long time.

Freddie Williams and Tom Kilburn of Manchester University in the UK built the first machine which worked according to the von Neumann design. They called it "Baby". It ran its first program on June 21, 1948, but it had no proper input/output equipment.

Maurice Wilkes built the EDSAC computer at Cambridge, England, to the von Neumann design. It had proper input/output equipment, and first ran in May 1949. For eighteen months it was the only fully working computer in the world.

Grace Hopper was involved in *electro-mechanical* calculators used for similar purposes to the ENIAC. It was the early to mid 1950's before she started her notable contributions to the ease of use of the new electronic computers.

Answer 5

Neumann János Lajos AKA John von Neumann

"By eight, he had mastered calculus; by twelve he was at the graduate level in mathematics reading such books as Emile Borel's "Theorie des Fonctions". His interests as a child were not confined to the realm of mathematics, though, and accounts tell of how, by eight years of age, he had completed his reading of all forty-four volumes of the universal history, which resided in the family’s library. Indeed, he could memorize pages on sight - a gift that later would continue to surprise even Nobel Prize laureates. He loved to invent mechanical toys, and was an expert on the Civil War, the trial of Joan of Arc, and Byzantine history.

He entered the Lutheran Gymnasium in Budapest in 1911. In 1913, his father purchased a title, and the Neumann family acquired the Hungarian mark of nobility Margittai, or the Austrian equivalent von. Neumann János therefore became János von Neumann — a name that he later changed to the German Johann von Neumann. After teaching as history's youngest Privatdozent of the University of Berlin from 1926 to 1930, he, his mother, and his brothers emigrated after Hitler's rise to power from Germany to the United States in the 1930s. Curiously, while he anglicized Johann to John , he kept the Austrian-aristocratic surname of von Neumann, whereas his brothers adopted the different surnames of Vonneumann and Newman.

Although von Neumann unfailingly dressed formally, with suit and tie, he enjoyed throwing the most extravagant parties and driving hazardously (frequently while reading a book, and sometimes crashing into a tree or getting himself arrested as a consequence). He was a profoundly committed hedonist who liked to eat and drink heavily (it was said that he knew how to count everything, except calories), tell dirty stories and very insensitive jokes (e.g. "bodily violence is a displeasure done with the intention of giving pleasure"), and insistently gaze at the legs of young women (so much so that the female secretaries at Los Alamos were often compelled to cover up the exposed undersides of their desks with sheets of paper or cardboard.)"

Answer 6

Modern algorithmic computers were developed in the later 1940s by a slew of people, most notably among them was one Admiral Grace Hopper. She was part of the team of geniuses who developed binary and the machine to use it. Google her name...
