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.

Meanwhile, Babbage's attention had moved on to developing an analytical engine, further undermining the government's confidence in the eventual success of the difference engine. By improving the concept as an analytical engine, Babbage had made the difference engine concept obsolete, and the project to implement it an utter failure in the view ...
Ada Lovelace. In 1840, Charles Babbage was invited to give a seminar in Turin on his analytical engine, [12] the only public explanation he ever gave on the engine. [13] During Babbage's lecture, mathematician Luigi Menabrea wrote an account of the engine in French. [12]
Difference Engine, 1822 – Charles Babbage's mechanical device to calculate polynomials. Analytical Engine, 1837 – A later Charles Babbage device that could be said to encapsulate most of the elements of modern computers. Odhner Arithmometer, 1873 – W. T.

Babbage, Charles: Originated the concept of a programmable general-purpose computer; designed the Analytical Engine and built a prototype for a less powerful mechanical calculator. 1973 Bachman, Charles: Outstanding contributions to database technology. [7] 1954, 1963 Backus, John
Replica of the Difference Engine in the Science Museum, reconstructed after studies of Charles Babbage's original drawings by Allan Bromley. Most discussions of the history of computing start with Charles Babbage, and what we know about Charles Babbage's Difference and Analytical engines really starts with the scholarship of Allan Bromley.
Ada Lovelace's note G on the Analytical Engine from 1842 describes an algorithm for generating Bernoulli numbers with Babbage's machine; [5] it is disputed whether Lovelace or Babbage developed the algorithm. As a result, the Bernoulli numbers have the distinction of being the subject of the first published complex computer program.
