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.
The London Science Museum's difference engine, the first one actually built from Babbage's design. The design has the same precision on all columns, but in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.

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]
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.
