Charles Babbage

Charles Babbage (1791-1871) was born in Walworth, Surrey, on December 26, 1791. He was one of four children born to the banker Benjamin Babbage and Elizabeth Tempe. He died on October 18, 1871 and was buried at Kensal Green cemetery in London. He was elected a fellow of the Royal Society in 1816 and occupied the Lucasian chair of mathematics at Cambridge University from 1828 to 1839.
The father of Charles was a rich man, so it was possible for Charles to receive instruction from several elite schools and teachers during the course of his elementary education. He was about eight when he had to move to a country school to recover from a dangerous fever. His parents sentenced that his "brain was not to be taxed too much"; Babbage wrote: "this great idleness may have led to some of my childish reasonings."Babbage arrived at Trinity College, Cambridge in October 1810. He had a big culture - he knew Lagrange, Leibniz, Lacroix, Simpson... and he was seriously disappointed about the math programs available at Cambridge. So he, with J.Herschel, G.Peacock, and other friends, decided to form the Analytical Society.
