Editing Denis Papin (section)

==Career==
In 1673, Papin worked with [[Christiaan Huygens]] and [[Gottfried Leibniz]] in Paris, and became interested in using a [[vacuum]] to generate motive power.

In 1675, he first visited London, where he worked with [[Robert Boyle]] from 1676 to 1679, publishing an account of his work in ''Continuation of New Experiments'' (1680).<ref>Anita McConnell, 'Papin, Denis (1647–1712?)', ''[http://www.oxforddnb.com/view/article/21249 Oxford Dictionary of National Biography]'', Oxford University Press, 2004, accessed 29 April 2006]</ref> During this period, Papin invented the ''[[steam digester]],'' a type of [[pressure cooker]] with a [[safety valve]]. He first addressed the Royal Society in 1679 on the subject of his digester, and remained mostly in London. As a [[Huguenot]], Papin found himself greatly affected by the increasing restrictions placed on Protestants by [[Louis XIV of France]] and by the King's ultimate revocation of the [[Edict of Nantes]] in 1685.

In Germany, he was able to live with fellow Huguenot exiles from France, so in about 1687, he left to take up an academic post in Germany.

In 1689, Papin suggested that a force pump or bellows could maintain the pressure and fresh air inside a [[diving bell]]. (Engineer [[John Smeaton]] utilised this design in 1789.<ref name=davis1955>{{cite book |author=Davis, RH |author-link=Robert Davis (inventor) |title=Deep Diving and Submarine Operations |year=1955 |edition=6th |publisher=[[Siebe Gorman|Siebe Gorman & Company Ltd]] |location=Tolworth, Surbiton, Surrey |page=693 }}</ref><ref name=dive_hx>{{cite journal |last=Acott |first=C. |title=A brief history of diving and decompression illness. |journal=South Pacific Underwater Medicine Society Journal |volume=29 |issue=2 |year=1999 |issn=0813-1988 |oclc=16986801 |url=http://archive.rubicon-foundation.org/6004 |archive-url=https://web.archive.org/web/20080627230124/http://archive.rubicon-foundation.org/6004 |url-status=usurped |archive-date=27 June 2008 |access-date=17 March 2009 }}</ref>)

While in [[Marburg]] in 1690, having observed the mechanical power of atmospheric pressure on his 'digester', Papin built a model of a piston [[steam engine]], the first of its kind.  In 1705 while teaching mathematics at the [[University of Marburg]],<ref name=Acemog>{{cite Q|Q7997840}}<!-- Why Nations Fail: The Origins of Power, Prosperity, and Poverty -->.</ref> he developed a second steam engine with the help of [[Gottfried Leibniz]], based{{Citation needed|date=August 2020|reason=Papin worked on steam engines since before 1690, so a citation is required.}} on an invention by [[Thomas Savery]], but this used steam pressure rather than atmospheric pressure.  Details of the engine were published in 1707.

In 1705, Papin constructed a ship powered by hand-cranked paddles. An apocryphal story originating in 1851 by [[Louis Figuire]] held that this ship was steam-powered rather than hand-powered and that it was therefore the first steam-powered vehicle of any kind. The myth was refuted as early as 1880 by {{ill|Ernst Gerland|de|Ernst Gerland (Physiker)}}, though still it finds credulous expression in some contemporary scholarly work.<ref name=wootton>{{cite book |author=Wootton, David|title=The Invention of Science |year=2015|publisher=Harper Collins |location=New York |page=498,647 }}</ref>

Papin's ship was said to have been destroyed in 1707 by the boatmen of [[Hann. Münden|Munden]] who feared it would threaten their livelihood.<ref>{{Cite journal |last=Valenti |first=Philip |date=December 1979 |title=A Case Study of British Sabotage Leibniz, Papin, and The Steam Engine |url=http://21sci-tech.com/Articles%202008/papin_steam_engine.pdf |journal=Fusion |pages=41 |via=sci-tech}}</ref> The scene of boatmen destroying Papin's ship is depicted in several pieces of art in the eighteenth century and serves as an example of the resistance and fear inspired by the creative destruction that accompanies new technology.<ref>{{Cite web |last=LIBRARY |first=SCIENCE, INDUSTRY & BUSINESS LIBRARY/NEW YORK PUBLIC LIBRARY/SCIENCE PHOTO |title=Destruction of Papin's steamboat, 1707 - Stock Image - V900/0062 |url=https://www.sciencephoto.com/media/364656/view/destruction-of-papin-s-steamboat-1707 |access-date=2024-04-17 |website=Science Photo Library |language=en}}</ref><ref>{{Cite web |last=Limited |first=Alamy |title=Destruction of Denis Papin Steamboat,1707 Stock Photo - Alamy |url=https://www.alamy.com/destruction-of-denis-papin-steamboat1707-image151886440.html |access-date=2024-04-17 |website=www.alamy.com |language=en}}</ref>

Later,{{when|date=January 2021}} at the iron foundry in Veckerhagen (now [[Reinhardshagen]]), he cast the world's first steam cylinder.

In 1707, Papin returned to London leaving his wife in Germany. Several of his papers were put before the Royal Society between 1707 and 1712 without acknowledging or paying him, about which he complained bitterly. Papin's ideas included a description of his 1690 atmospheric steam engine, similar to that built and put into use by [[Thomas Newcomen]] in 1712, thought to be the year of Papin's death.
