Ada Lovelace Charles Babbage, born December 26,LondonEngland —died October 18,LondonEnglish mathematician and inventor who is credited with having conceived the first automatic digital computer.

In Babbage helped found the Analytical Society, whose object was to introduce developments from the European continent into English mathematics. In he was elected a fellow of the Royal Society of London.

He was instrumental in founding the Royal Astronomical and Statistical societies. Wellcome Library, London CC BY 4.

Later he made a small calculator that could perform certain mathematical computations to eight decimals. Then in he obtained eric weisstein world of biography support for the design of a projected machinethe Difference Enginewith a decimal capacity. Its construction required the development of mechanical engineering techniques, to which Babbage of necessity devoted himself.

In the meantime —39he served as Lucasian Professor of Mathematics at the University of Cambridge. The Difference Engine Science Museum London During the mids Babbage developed erics weisstein world of biography for the Analytical Enginethe forerunner of the modern digital computer.

In that device he envisioned the capability of performing any arithmetical operation on the basis of instructions from punched cards, a memory unit in which to store numbers, sequential control, and most of the other basic elements of the present-day computer.

The Analytical Engine, however, was never completed. In British scientists built Difference Engine No.

Continuum hypothesis

Babbage made notable contributions in other areas as well. He assisted in establishing the modern postal system in England and compiled the first reliable actuarial tables.

He also invented a type of speedometer and the locomotive cowcatcher. Charles Babbage, engraving from Library of Congress, Washington, D. LC-USZ Learn More in these related articles:
