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.

Babbage went on to design his much more general analytical engine, but later designed an improved "Difference Engine No. 2" design (31-digit numbers and seventh-order differences), [9] between 1846 and 1849. Babbage was able to take advantage of ideas developed for the analytical engine to make the new difference engine calculate more quickly ...
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]
Babbage conceived, and began to design, his decimal 'Analytical Engine'. [30] A program for it was to be stored on read-only memory, in the form of punched cards. Babbage continued to work on the design for years, though after about 1840 design changes seem to have been minor.
Babbage argued that on the contrary, his experience programming the analytical engine, an early computer, enabled him to conceive of God that might design a complex, programmed world. [ 3 ] The book is a work of natural theology , an attempt to reconcile science and religion, and incorporates extracts from related correspondence of John ...
It seems that Ludgate worked as a clerk for an unknown corn merchant, in Dublin, and pursued his interest in calculating machines at night. [6] Charles Babbage in 1843 and Ludgate in 1909 designed the only two mechanical analytical engines before the electromechanical analytical engine of Leonardo Torres Quevedo of 1920 and its few successors, and the six first-generation electronic analytical ...
The use of the word Engine was in homage to Charles Babbage and his Difference Engine and Analytical Engine. Turing's technical design Proposed Electronic Calculator was the product of his theoretical work in 1936 "On Computable Numbers" [3] and his wartime experience at Bletchley Park where the Colossus computers had been successful in ...
