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.

The links connect especially his mathematical researches in functional equations with his work on mathematical tables and on calculating machines, but they are evident also in some of his social and industrial concerns. Evidence is presented to show that Babbage was consciously aware of at least some of these links. Attention to them casts light upon his achievements.

50. Charles Babbage Today, Charles Babbage (17911871) is acknowledged as the father of modern computersbecause he foresaw what its basic elements required storage, mill, control http://www.surveyhistory.org/charles_babbage.htm

Article taken from "Backsights" Magazine published by Surveyors Historical Society CHARLES BABBAGE by Mary M. Root Charles Babbage was a prodigal mathematician, a social charmer, a renaissance personality, and a genius whose life-work predicated the modern computer. Babbage's creations were the Difference engines, so called because they were designed to compute tables of numbers according to the method of finite differences, and the more complex Analytical Engines, which utilized the concern of feeding the results of calculations back into the beginning of subsequent calculations. Today, Charles Babbage (1791-1871) is acknowledged as the father of modern computers because he foresaw what its basic elements required: storage, mill, control, input, output, decision-making, repetition and programs. Unfortunately, the brilliant Analytical Engine was never completed, due to a breach of faith and money from the British government and a lack of precision milling in that period. As a young man, Babbage worked with pure mathematics, haunting the London bookshops for works by Lacroix, Newton, Leibnitz, Woodhouse and Lagrange. In time, the self-taught Babbage invented the calculus of functions which was developed on lines analogous to differential equations and difference equations. His work with theory and notation showed clear insight, causing a modern-day biographer to lament: "The mathematical world is the poorer through Babbage never having developed nor published the 'Philosophy of Analysis'...It is almost tragic to think that (he) spent most of his remaining fifty years trying to devise suitable machinery for his engines. If he had developed the very fruitful ideas contained in the book....then it might well have been that mathematical philosophy, modern algebra, the theory of games and stochastic mathematics would have developed many decades before they actually did."

Babbage, Charles engelsk matematiker och uppfinnare (1791-1871), professor i matematik i Cambridge. Han tänkte ut den första datorn, den helt mekaniska så kallade analysmaskinen , men lyckades aldrig bygga den. Tillsammans med Ada Lovelace skrev Babbage de första dataprogrammen. Innan han tänkte ut den analysmaskinen konstruerade han den så kallade differensmaskinen , som var en avancerad räknemaskin men ingen dator. Den blev heller aldrig färdigbyggd, trots att brittiska regeringen satsade stora pengar på projektet. Att maskinerna aldrig blev byggda berodde på en kombination av omständigheter, bland annat att Babbage inte var ingenjör och inte behärskade det praktiska konstruktionsarbetet. Men eftersom han tänkte rätt räknas han som den förste datorkonstruktören.

Charles Babbage Charles Babbage was born in 1791 in Teignmouth, Devonshire, UK as the son of a banker called Benjamin Babbage. Some people know him as the "Father of Computing" as a result of his contributions to the basic design of the computer. A major contribution was his Analytic Machine. Before he built this he produced the Difference Engine (pictured below) which operated on 6-digit numbers, and was designed to solve 2nd order difference equations. Charles Babbage 1791-1871 However, only a few people knew who he was when he died in 1871 in London. But nowadays every person studying the history of the computer knows many things about him such as punch cards, chains and subassemblies. Ultimately the logical structure of the modern computer come from him. Near the northern pole of the moon there is even a crater named after Charles Babbage. The analytical engine devised by Charles Babbage included 5 features crucial to future computers: an input device a storage facility to hold numbers for processing a processor or number calculator a control unit to direct tasks to be performed an output device Unfortunately this engine never worked, because the technology of manufacturing exact technical parts was not developed far enough. This inaccuracies kept the machine from working.

Contact Us Charles Babbage T he Babbage Centre is named in honour of local boy Charles Babbage (1791-1871), who came from an old Devon family based near Totnes. His grandfather, Benjamin Babbage was mayor of Totnes in 1754. Babbage's father was a prosperous banker, who moved between London and Devon for many years. The family had a farm at Dainton, just 4 miles from Totnes and adjacent to the railway line that Brunel was to build. They also had property in Teignmouth and Totnes. Charles's father retired to Totnes in 1803 and lived in Fore Street. The family was wealthy which meant that Charles could live comfortably without a paid occupation. C harles was born in Walworth, South London on 26th December 1791. He attended school at Exeter, Enfield and Totnes Grammar School - for two years. Cambridge was his university. At the age of 24 he set up residence in London, where he remained for the rest of his life. He became a member of the Royal Society in 1816, and was Lucasian chair of mathematics in Cambridge from 1828 to 1839. B abbage married Georgina Whitmore in 1814. His father was not well pleased so Charles spent part of his honeymoon (at Dartington Hall) trying to evade his father. Charles and Georgina had 8 children, of whom 3 survived. Georgina died in 1834 leaving Babbage a widower for the rest of his life. The marriage soured the relationship between Babbage and his father, but nonetheless he inherited his father's estate in 1827. Charles Babbage died on 18th October 1871 and is buried in Kensal Green Cemetery, London.

OCTOBER 2001 ISSUE comments or questions? email apsnews email webmaster October 1871: Babbage's Successful Failure-The First Computer Charles Babbage (1791-1871) Few 19th century devices have had as much influence on modern technology as Charles Babbage's calculating engines, most notably the Analytical Engine, a mechanical digital computer which anticipated virtually every aspect of present-day computers. First described in 1837, his vision of a massive brass, steam-powered, general-purpose mechanical computer inspired some of the greatest minds of the 19th century, but he failed to persuade any backer to provide funds to actually construct the device. However, his ingenuity earned him recognition as the "father of computing" more than 100 years after his death. The son of a London banker, Babbage was a tinkerer from birth, doing little else with his toys save dissecting them. He taught himself algebra as a youth, and was so well read in the continental mathematics of his day that when he entered Trinity College, Cambridge, in 1811, he found himself far in advance of his tutors in the subject. With friends, Babbage co-founded the Analytical Society for promoting continental mathematics, and reforming the math of Newton currently taught at Cambridge. Most notably, he and his friends effected the crucial introduction of the Leibnitz notation in calculus, transforming mathematics throughout Great Britain.

Augusta Ada Byron (1815-1852) Augusta Ada Byron was born to Anna Isabella Milbanke and George Gordon Noel Byron (1788-1824), the famous poet Lord Byron, on 10 December 1815 in London, England. Lord Byron separated from his wife within months after Ada's birth. He left England in 1816 and never returned. He lived in Switzerland and Italy, and finally died of illness in 1824 at Missolonghi, Greece, where he had gone to fight for Greek independence from Turkey. Ada received mathematical tutoring from Augustus DeMorgan (1806-1871) . Ada's mother had an interest in mathematics and the desire to encourage the rational aspects of Ada's character in opposition to the romantic influences of her father. When she was 18, Ada heard a lecture about the difference engine designed by Charles Babbage (1791-1871) At 19 Ada married William King. Several years later he become the Earl of Lovelace, so she gained the title the Countess of Lovelace. They had two sons and a daughter: Byron Noel (1836), Anne Isabella (1837), and Ralph Gordon (1839). Beginning with a letter dated 18 January 1836 and continuing until her death, Ada wrote a large numbers of letters to Babbage.

HS 228 Lecture Week 2 Slot 1 Charles Babbage (1791-1871) After a chequered education (eg he learns maths largely by himself) he goes to Cambridge at the age of 19 Universities in the early 19th century were not very intellectual, and acted more like "finishing schools" for gentlemen Babbage with a few friends (eg astronomer John Herschel) set up a group to push for reform of mathematics by introducing better French maths: the Analytical Society In 1814, Babbage marries and goes to live in London the life if a gentleman professor gives lectures at the Royal Institution becomes a Fellow of the Royal Society (an elite society for top scientists and friends) Babbage was a mathematician, economist, political commentator, adviser to insurance business, and wrote on astronomy and engineering too He makes enemies, partly because of his personality: irascible, obsessive, radical and idiosyncratic eg Carlyle: "Babbage continues to be eminently unpleasant to me, with his frog mouth and viper eyes, with his hidebound, wooden irony, and the acridest egotism looking through it" One problem that Babbage came across again and again was the lack of accurate mathematical tables eg star positions to navigate a ship [why important?]
