Babbage is known for his ideas about building an "analytical engine", the predecessor of the digital computer. He proposed operations research which involves the idea of using machines to perform routine mathematical operations and thus deleting drudgery and errors in human calculation. Although he never built his computer, his ideas influenced those who later carried out his ideas.
Among Babbage's writings are Reflections on the Decline of Science in England written in 1831 and On the Economy of Machinery and Manufactures (1833).
Babbage died on October 18, 1871.
