Charles Babbage

About this figure

Charles Babbage (1791-1871) was an English mathematician, philosopher, and inventor best remembered as a pioneer of mechanical computing. Educated at Cambridge, he held the university's Lucasian Chair of Mathematics, a position once occupied by Isaac Newton, from 1828 to 1839, though he lectured little and devoted most of his energy to other projects. His central ambition was to eliminate human error from mathematical tables by building machines that could calculate automatically. The Difference Engine, begun in 1823 with British government funding, was designed to compute polynomial functions using the method of finite differences; despite years of work and considerable expense, construction stalled over disputes with his engineer and was formally abandoned in 1842, with no complete machine built in his lifetime. Babbage went on to design a far more ambitious device, the Analytical Engine, conceived in the 1830s as a general-purpose mechanical computer that could be programmed using punched cards, an idea borrowed from the Jacquard loom, and that included concepts recognizable today as memory and a processing unit. It, too, was never built, but Ada Lovelace's published notes on the machine, including what is often regarded as the first published computer algorithm, later gave Babbage's design a lasting place in the history of computing.

Frustrated by his repeated failures to secure sustained funding and by what he saw as the indifference of British scientific institutions, Babbage became an outspoken critic of the state of English science, publishing "Reflections on the Decline of Science in England" in 1830. His later memoir, "Passages from the Life of a Philosopher" (1864), recounts these disputes at length alongside his wide-ranging interests outside computing, including cryptography, actuarial science, and the economics of manufacturing, the subject of his 1832 book "On the Economy of Machinery and Manufactures." He was also known, and sometimes mocked, for eccentric public campaigns, including a long crusade against London street musicians. Babbage did not live to see his designs realized: it was not until 1991 that the Science Museum in London built a working Difference Engine No. 2 from his original drawings, proving that his calculations had been sound all along.
