There was little evidence to prove which was right until Hyman (see [8]) in 1975 found that Babbage's birth had been registered in St Mary's Newington, London on 6 January 1792. Babbage's father was Benjamin Babbage, a banker, and his mother was Betsy Plumleigh Babbage. Given the place that his birth was registered Hyman says in [8] that it is almost certain that Babbage was born in the family home of 44 Crosby Row, Walworth Road, London.

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.

Biography Charles Babbage (1791-1871) Although born in London, Babbage came from an old Totnes family, and retained close links with the region all his life. The West Country, with its mining and engineering was particularly important in the early stages of the industrial revolution, and from the extraordinarily wealthy Totnes region, with its port at Dartmouth, came also Newcomen and Savery, pioneers of the steam engine. Babbage went up to Cambridge in 1810 and with some friends effected the crucial introduction of the Leibnitz notation for the calculus, which transformed mathematics in Cambridge and thus throughout Britain. In 1814 Babbage married Georgiana Whitmore, from a landowning Shropshire family. Her half brother, Wolryche Whitmore, was the M.P. who rose year after year in the House of Commons to move the repeal of the Corn Laws. He was also a leading member of the Political Economy Club, and played an important part in Babbage's life. Babbage's greatest achievement was his detailed plans for Calculating Engines, both the table-making Difference Engines and the far more ambitious Analytical Engines, which were flexible and powerful, punched-card controlled general purpose calculaters, embodying many features which later reappeared in the modern stored program computer. These features included: 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.

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.

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.
