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.
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]

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". [ 6 ]
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.
Charles Babbage's first public exposition about his Analytical Engine at Accademia delle Scienze, Turin. [31] 1842 France: Timoleon Maurel patented the Arithmaurel, a mechanical calculator with a very intuitive user interface, especially for multiplying and dividing numbers because the result was displayed as soon as the operands were entered.
Among his notable publications: Sketch of the Analytical Engine Invented by Charles Babbage, Esq. with notes by translator Ada Lovelace (1842), which described many aspects of computer architecture and is considered the first modern example of programming. Both are available on Wikisource.
A demo of Babbage's unfinished Difference engine was on display for guests at some of the gatherings. [8] He also displayed a mechanical dancer. [9] In her autobiography, Harriet Martineau describes Babbage's disappointment at his guests being more interested in this dancing doll - a toy - than in his demo of a computing machine. [3]
