Engraving of Charles Babbage, an English mathematician, born December 1792, died October 1871. In 1823 Babbage began work on the Difference Engine no.1, an early adding machine. A portion was built in 1833, but the project was abandoned as Babbage became involved in designing a more complicated machine, the Analytical Engine.
