2. Babbage, Charles (1791-1871) -- From Eric Weisstein's World Of Scientific Biogra Babbage, Charles (17911871), This entry contributed by MargheritaBarile. English mathematician and inventor. Babbage was obsessed http://scienceworld.wolfram.com/biography/Babbage.html

Branch of Science Engineers Branch of Science Mathematicians ... Barile Babbage, Charles (1791-1871) This entry contributed by Margherita Barile English mathematician and inventor. Babbage was obsessed from his boyhood with the idea of an universal language, and he conceived his first mechanical calculator around 1812 while he was a student at the Trinity College in Cambridge, England. At that time, he was involved in research on differential and integral calculus as a co-founder of the new Analytical Society. Later, he would become Lucasian professor (1828) and contribute to establishing the Royal Astronomical Society (1820) and the London Statistical Society (1834). The project of Babbage's Difference Engine No. 1 was completed in 1822. Two improved versions followed in the next years, but were never realized. These devices, based on a system of toothed gears, could automatically compute arithmetical sequences of high order involving numbers having up to 5 digits. Babbage's (unachieved) masterpiece was the Analytical Engine, a much more sophisticated invention, which worked using punched cards, could perform any arithmetical operation, and was even able to print out the results. One of the main outcomes of Babbage's research was the conclusion that every game of skill could be played by a properly instructed automaton.

Charles Babbage, 1791-1871 Charles Babbage wurde im Jahre 1791 vermutlich in der Nähe von London als Sohn eines Bankers geboren. Aufgrund der guten finanziellen Lage der Familie konnte Charles eine Privatschule in London besuchen. Schon in jungen Jahren zeigte sich, dass er die Gabe hatte, selbst komplizierte mathematische Probleme auf eine unkomplizierte Art erklären zu können. Auf der anderen Seite hatten die Lehrer grosse Probleme, dem Jungen wenigstens ein Wenig klassische Bildung auf den Weg zu geben; Geisteswissenschaften waren klar nicht die Stärke des Sprösslings. Nach dem Abschluss seines Mathematistudiums übte er sich im Selbststudium und verfasste mit Freunden, die meisten unter ihnen bekannte Mathematiker und Physiker, kleine Arbeiten, wodurch er auf sich aufmerksam machte. Er fand Anerkennung in der Mathematiker-Gesellschaft, was für die damalige Zeit grundlegend für jede Mathematikerkarriere war. Er begab sich auf einen Exkurs in die Astronomie, wobei ihm immer die Notwendigkeit einer funktionierenden Rechenmaschine bewusst wurde, die Tabellen berechnen kann, um den Mathematikern diese mühsame Arbeit abzunehmen; vor allem war man damals im Begriff, Logaritmen- und trigonometrische Tabellen zu fertigen. Er begann Pläne für ein derartiges Gerät zu fertigen und schrieb anno 1822 einen Brief an die Dachorganisation der Astronomen Englands. Diese waren begeistert von dieser Idee und gewährten Babbage eine Summe von 1'500£ für die Fertigung, welche nach Babbage etwa drei Jahre in Anspruch nehmen sollte.

Introduction The calculating engines of English mathematician Charles Babbage (1791-1871) are among the most celebrated icons in the prehistory of computing. Babbage’s Difference Engine No.1 was the first successful automatic calculator and remains one of the finest examples of precision engineering of the time. Babbage is sometimes referred to as "father of computing." The Charles Babbage Foundation took his name to honor his intellectual contributions and their relation to modern computers. Biographical note Charles Babbage was born in London on December 26, 1791, the son of Benjamin Babbage, a London banker. As a youth Babbage was his own instructor in algebra, of which he was passionately fond, and was well read in the continental mathematics of his day. Upon entering Trinity College, Cambridge, in 1811, he found himself far in advance of his tutors in mathematics. Babbage co-founded the Analytical Society for promoting continental mathematics and reforming the mathematics of Newton then taught at the university. In his twenties Babbage worked as a mathematician, principally in the calculus of functions. He was elected a Fellow of the Royal Society in 1816 and played a prominent part in the foundation of the Astronomical Society (later Royal Astronomical Society) in 1820. It was about this time that Babbage first acquired the interest in calculating machinery that became his consuming passion for the remainder of his life.

Charles Babbage (1791-1871) John van Wyhe Charles Babbage was an astonishingly original and innovative thinker in Victorian Britain. Many innovations and important contributions are attributed to him including his idea for machines to perform mathematical calculations (his Calculating Engines) and the far more ambitious Analytical Engines which were flexible punch-card controlled general calculaters, he produced a Table of logarithms of the natural numbers from 1 to 108000 which was a standard reference from 1827 through the end of the century. Babbage pioneered many other technical innovations as well as developing mathematical code breaking. Babbage's Analytical Engine designs are particularly impressive today as they contained many similar elements to modern digital computers. For example, Babbage's engines 'punched card control; separate store and mill; a set of internal registers (the table axes); fast multiplier/divider; a range of peripherals; even array processing' (Hyman). The Science Museum assembled Babbage's Calculating Engine number 2 according to his original designs in 1991. To witness the whirl and thudding stamp of this machine is a thrilling experience.

Charles Babbage Fascinating facts about Charles Babbage inventor of the first mechanical computing machine in the 1820s. Babbage, Charles (1792-1871), British mathematician and inventor, who designed and built mechanical computing machines on principles that anticipated the modern electronic computer. Babbage was born in Teignmouth, Devonshire, and was educated at the University of Cambridge. He became a fellow of the Royal Society in 1816 and was active in the founding of the Analytical, the Royal Astronomical, and the Statistical societies. In the 1820s Babbage began developing his Difference Engine, a mechanical device that can perform simple mathematical calculations. Babbage started to build his Difference Engine, but was unable to complete it because of a lack of funding. However, in 1991 British scientists, following Babbage's detailed drawings and specifications, constructed the Difference Engine. The machine works flawlessly, calculating up to a precision of 31 digits, proving that Babbage's design was sound.

Babbage, Charles mathematician england 26 Dec 1791, Teignmouth, Devonshire - 18 Oct 1871, London Grave location: London: Kensal Green Cemetery, Kensal Green Born in Devonshire as the son of the banker Benjamin Babbage. As a child he suffered ill health. The young Babbage clearly had a passion for mathematics and a disdlike for the classics. He was educated by private tutors and then at Trinity College, Cambridge, where he received his M.A. in 1817. In 1830 he designed an analytical engine (on paper), which operated in a way similar to computers. Another of his designs was a difference engine, meant to produce tables. In 1827 he produced a table of logarithms from 1 to 108000; Babbage wanted to quantify everything. 1827 had been a year full of disaster. His father, his wife and two of his children died and he went abroad for his own health. Back in England he obtained the Lucasian Chair at Cambridge in 1828, but he never presented a single lecture. Babbage was one of the founders of the Astronomical Society (1820) as well as the Statistical Society (1834). In 1834 work on the Difference Engine came to an end. The government granted no more money and Babbage had already invested a huge sum of his own. In 1840 he visited Turin, where he discussed his work with mathematicians like Menabrea. Lady Ada Augusta Lovelace - Lord Byron's daughter - translated Menabrea's description of the analytical engine and extended it significantly by herself. She assisted Babbage on some of his projects and he was very fond of her.

Search Inventors Charles Babbage 1791-1871 The earliest known modern computer device was the analytical engine invented by Charles Babbage. Charles Babbage's mechanical analytical engine had a processing unit called the mill, stored number programs, used punch cards for data input, and printed an output. Being mechanical rather than electrical, the analytical engine worked by a series of gears and levers. Charles Babbage started building his analytical engine in 1833 and continued to tinker on his machine until the day he died. According to public lecture given by Philip Machanick at the University of the Witwatersrand: "What made the analytical engine such a feat of engineering was that it was built before the discovery of electronics, and was entirely mechanical. Its memory consisted of gears, while the processing unit, or mill, consisted of cams, clutches, cranks and gears. The analytical engine project grew out of an earlier, less ambitious project, the difference engine. Where the difference engine did a relatively fixed computation, the analytical engine was designed to be a truly general computational device. The use of cards to record a program was inspired by the

Charles Babbage (1791-1871) In the history of computers, Charles Babbage is often celebrated as the "first computer pioneer" and as a scientist and inventor who was 100 years ahead of his time. This reputation is primarily based on the invention of the Analytical Engine, a mechanical automatic calculating machine which featured an arithmetic and logic unit, memory, input/output, and sequential control by means of punched cards. Charles Babbage, the son of a banker born in 1791 in Walworth, England, studied mathematics at Cambridge University from 1810 to 1814. In 1816, he became a Fellow of the Royal Society of London, the most important scientific society in England. Following the death of his father, he was financially independent and exerted great influence on the evolution of science in England without ever holding an official post. He was not only an outstanding mathematician and inventor but also a reformer of science and society. Babbage's initial fame was due to the invention of the Difference Engine. His occupation with the preparation of mathematical tables - a time-consuming activity that was prone to error - gave him the idea in 1821 of doing this automatically with the aid of a machine which would total differences. Construction of the Difference Engine, which was to consist of 25,000 parts, developed into one of the first large-scale scientific projects, although it ultimately failed. In 1833, work on construction of the machine was discontinued after a dispute between Babbage and the engineer Joseph Clement. By then, more money had been spent on this project than would have been needed to build 20 steam locomotives. Finally, it was other inventors who built the first working difference engines, but they were all influenced by Babbage's ideas.
