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]
After the attempt at making the first difference engine fell through, Babbage worked to design a more complex machine called the Analytical Engine. He hired C. G. Jarvis, who had previously worked for Clement as a draughtsman. [162] The Analytical Engine marks the transition from mechanised arithmetic to fully-fledged general purpose computation.
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. She was the first to recognise that the machine had applications ...
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".

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.
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.
Charles Babbage describes an Analytical Engine, the first mechanical, general-purpose programmable computer. [33] [34] The Cooke and Wheatstone telegraph, the first commercially successful electric telegraph, is designed by Sir Charles Wheatstone and Sir William Fothergill Cooke. [35] [36] [37] 1839. A pedal bicycle is invented by Kirkpatrick ...
