The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator.

Charles Babbage began to construct a small difference engine in c. 1819 [4] and had completed it by 1822 (Difference Engine 0). [5] He announced his invention on 14 June 1822, in a paper to the Royal Astronomical Society, entitled "Note on the application of machinery to the computation of astronomical and mathematical tables".

Computer: A History of the Information Machine is a history of computing written by Martin Campbell-Kelly and William Aspray first published in 1996. It follows the history of "information machines" from Charles Babbage's difference engine through Herman Hollerith's tabulating machines to the invention of the modern electronic digital computer.
