It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer.

J. Presper Eckert and John W. Mauchly similarly were not aware of the details of Babbage's Analytical Engine work prior to the completion of their design for the first electronic general-purpose computer, the ENIAC.

The Engine is not a replica ( one was never built during Babbage's lifetime ); therefore this is the first one-the original.

British countess and mathematician Ada Lovelace is popularly credited as history's first programmer, as she was the first to express an algorithm intended for implementation on a computer, Charles Babbage's analytical engine, in October 1842, intended for the calculation of Bernoulli numbers.

Her work never ran because Babbage's machine was never completed to a functioning standard in her time ; the first programmer to successfully run a program on a functioning modern electronically based computer was pioneer computer scientist Konrad Zuse, who achieved this feat in 1941.

Charles Babbage's analytical engine ( 1830s ) would have been the first Turing-complete machine if it had been built at the time it was designed.

* Ada Lovelace translates and expands Menabrea's notes on Charles Babbage's analytical engine, including an algorithm for calculating a sequence of Bernoulli numbers, regarded as the world's first computer program.

The Science Museum now holds a collection of over 300, 000 items, including such famous items as Stephenson's Rocket, Puffing Billy ( the oldest surviving steam locomotive ), the first jet engine, a reconstruction of Francis Crick and James Watson's model of DNA, some of the earliest remaining steam engines, a working example of Charles Babbage's Difference engine ( and the latter, preserved half brain ), the first prototype of the 10, 000-year Clock of the Long Now, and documentation of the first typewriter.

The first design for a program-controlled computer was Charles Babbage's Analytical Engine in the 1830s.

She is also considered to have been the world's first computer programmer, having written the first algorithm intended to be processed by a machine -- Charles Babbage's analytical engine.

She is credited as being the first programmer, having assisted in realising the potential of Babbage's analytical engine.

There are orbits of size 1 and there are no orbits of size p. Thus we first obtain Babbage's theorem

Joseph Clement ( 1779 – 28 February 1844 ) was a British engineer and industrialist, chiefly remembered as the maker of Charles Babbage's first Difference engine, between 1824 and 1833.

Ludgate also helped advance calculators by expanding Charles Babbage's design for the first programmable computer.

) Henry Babbage's " Analytical Engine Mill " is on display at the Science Museum in London.

Babbage's birthplace is disputed, but he was most likely born at 44 Crosby Row, Walworth Road, London, England.

During the 1980s, Allan Bromley, an associate professor at the University of Sydney, Australia, studied Babbage's original drawings for the Difference and Analytical Engines at the Science Museum library in London.

Replacement of the hard-to-implement decimal system ( used in Charles Babbage's earlier design ) by the simpler binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time.

While at Clement's workshop he helped with the manufacture of Charles Babbage's calculating machine, the Difference engine.

In 2005, Tim Robinson displayed his own Meccano differential analyser at the Computer History Museum, at Mountain View, California, USA, and Robinson has also built and exhibited two models of Charles Babbage's difference engine, also using Meccano.

It was not until the mid-19th century ( in Babbage's secret work during the Crimean War and Friedrich Kasiski's generally equivalent public disclosure some years later ), that cryptanalysis of well-implemented polyalphabetic ciphers got anywhere at all.

Although Babbage's design was technically feasible, no one had built a mechanical device to such exacting standards before, so the engine proved to be much more expensive than anticipated.

However, up to the 1940s, many subsequent designs ( including Charles Babbage's machines of the 1822 and even ENIAC of 1945 ) were based on the decimal system ; ENIAC's ring counters emulated the operation of the digit wheels of a mechanical adding machine.

* In common with many other complex mechanical devices, Charles Babbage's analytical engine used banks of cams to control each operation, i. e. it had a read-only control store.

Among the most complex were Babbage's difference and analytical engines, which were mechanical versions of computers.

The modern notion of records in computer science, with fields of well-defined type and size, was already implicit in 19th century mechanical calculators, such as Babbage's Analytical Engine.

To supervise his collections Darwin had to return to London, and on Lyell's advice he planned to arrive on Friday 3 March 1837, in time for one of Charles Babbage's Saturday parties, talking shops about the latest developments " brilliantly attended by fashionable ladies, as well as literary and scientific gents " and " a good mixture of pretty women ", bankers and politicians, where Babbage promoted such projects as his mechanical computer.

Despite this, Babbage's work fell into historical obscurity and the Analytical Engine was unknown to builders of electro-mechanical and electronic computing machines in the 1930s and 1940s when they began their work, resulting in the need to re-invent many of the architectural innovations Babbage had proposed.

The device was inspired by the similar work done by Per Georg Scheutz and has similarities with Charles Babbage's difference engine.

In 1991, the London Science Museum built a complete and working specimen of Babbage's Difference Engine No. 2, a design that incorporated refinements Babbage discovered during the development of the Analytical Engine.

* The cyberpunk novelists William Gibson and Bruce Sterling co-authored a steampunk novel of alternative history titled The Difference Engine in which Babbage's Difference and Analytical Engines became available to Victorian society.

June 14: Charles Babbage | Babbage's Difference engine.

He was influential in publicising Charles Babbage's Difference engine.

Aiken was inspired by Charles Babbage's Difference Engine.

Some notable examples include the reconstruction of Babbage's Difference engine ( more than a century after its design ) and the implementation of Plankalkül in 2000 ( more than half a century since its inception ).

Jacquard looms and Charles Babbage's Difference Engine both had simple, extremely limited languages for describing the actions that these machines should perform.

In October 2010, John Graham-Cumming started a campaign to raise funds by " public subscription " to enable serious historical and academic study of Babbage's plans, with a view to then build and test a fully working virtual design which will then in turn enable construction of the physical Analytical Engine.

Howard Aiken, who built the quickly-obsoleted electromechanical calculator, the Harvard Mark I, between 1937 and 1945, praised Babbage's work likely as a way of enhancing his own stature, but knew nothing of the Analytical Engine's architecture during the construction of the Mark I, and considered his visit to the constructed portion of the Analytical Engine " the greatest disappointment of my life ".

* In the Neal Stephenson novel The Diamond Age, ubiquitous molecular nanotechology is described to make use of " rod logic " similar to that imagined by Babbage's design for the Analytical Engine.

* Moriarty by Modem, a short story by Jack Nimersheim, describes an alternate history where Babbage's Analytical Engine was indeed completed and had been deemed highly classified by the British government.

This short story follows Holmes as his program is rebooted on modern computers and he is forced to compete against his nemesis yet again in the modern counterparts of Babbage's Analytical Engine.

Its design was influenced by Babbage's Analytical Engine, using decimal arithmetic and storage wheels and rotary switches in addition to electromagnetic relays.

During a nine-month period in 1842-1843, Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea about Charles Babbage's newest proposed machine, the Analytical Engine.

Working alone, Ludgate designed an Analytical Engine while unaware of Charles Babbage's designs, although he later went on to write about Babbage's machine.
