Charles Babbage KH FRS (/ ˈ b æ b ɪ dʒ /; 26 December 1791 – 18 October 1871) was an English polymath. [1] A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.
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.
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".

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.
Built the first electronic digital computer, the Atanasoff–Berry Computer, though it was neither programmable nor Turing-complete. 1822, 1837 Babbage, Charles: Originated the concept of a programmable general-purpose computer; designed the Analytical Engine and built a prototype for a less powerful mechanical calculator. 1973 Bachman, Charles
Charles Babbage: Pioneer of the Computer is a biographical book about the Victorian computer pioneer Charles Babbage (1791–1871). The book was written by Anthony Hyman (1928–2011), a British historian of computing.
Charles Babbage is often regarded as one of the first pioneers of computing. Beginning in the 1810s, Babbage had a vision of mechanically computing numbers and tables. Putting this into reality, Babbage designed a calculator to compute numbers up to 8 decimal points long.
Computer: A History of the Information Machine is a history of computing written by Martin Campbell-Kelly and William Aspray first published in 1996. It follows the history of "information machines" from Charles Babbage's difference engine through Herman Hollerith's tabulating machines to the invention of the modern electronic digital computer.
