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.

Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852), also known as Ada Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine.
The incomplete Difference Engine No. 1 was put on display to the public at the 1862 International Exhibition in South Kensington, London. [13] [14] 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 ...
Note G, originally published in Sketch of The Analytical Engine Invented by Charles Babbage. Note G [a] is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine.
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. Odhner's calculator who had millions of clones manufactured until the 1970s.
In his work Essays on Automatics, published in 1914, Torres Quevedo formulates what will be a new branch of engineering: automation and designed an electromechanical version of Babbage's Analytical engine which introduced floating-point arithmetic. 1991 Torvalds, Linus: Created the first version of the Linux kernel. 1965 Tukey, John W.
The first known computer algorithm was written by Ada Lovelace in the 19th century for the Analytical Engine, to translate Luigi Menabrea's work on Bernoulli numbers for machine instruction. [3] However, this remained theoretical only - the lesser state of engineering in the lifetime of these two mathematicians proved insufficient [ citation ...
