Famous French People

	Denis Papin - LoveToKnow 1911
		Shortly after the publication of the Experiences, Papin, who had crossed to London, was hospitably received by Robert Boyle, whom he assisted in his laboratory and with his writings.
		About this time also he introduced into the air-pump the improvement of making it with double barrels, and replacing by the two valves the turncock hitherto used; he is said, moreover, to have been the first to use the plate and receiver.
		Papin, on his arrival in London, found himself without resources and almost without friends; applications through Sir Hans Sloane to the Royal Society for grants of money were made in vain, and he died in total obscurity, probably about the beginning of 1712.

	Denis Papin - Wikipedia, the free encyclopedia
		A Huguenot, Papin's life was greatly affected by the increasing restrictions placed on Protestants by Louis XIV of France and the King's ultimate revocation of the Edict of Nantes in 1685.
		Denis Papin fled to London where the last evidence of his whereabouts was a letter he wrote dated January 23, 1712.
		Papins ideas included a description from 20 years earlier of an atmospheric steam engine, the likes of which was built and put into use by Thomas Newcomen in 1712, coincidentally thought to be the year of Papins death.

	Denis Papin Summary
		Denis Papin was an early pioneer in the study of steam pressure.
		Papin's best-known and most influential invention was his 1679 steam "digester," a direct forerunner of modern pressure cookers and hospital steam sterilizers.
		A Huguenot, Papin's life was greatly affected by the increasing restrictions placed on Protestants by Louis XIV of France and the King's ultimate revocation of the Edict of Nantes in 1685.

	Denis Papin
		Papin could at least make the operation of the engine more secure with his invention of a touch-pan.
		Papin also invented a geared piston bar, which could turn a cogwheel while the piston slided downward during the work period of the engine.
		Papin was more successful in inventing other different things besides steam power.

	Papin, Denis (Site not responding. Last check: 2007-10-16)
		Papin was born in Blois, on the Loire, and studied medicine at Angers.
		Papin worked with Huygens and Irish physicist Robert Boyle on an air pump and invented the condensing pump.
		In 1690, Papin suggested a cylinder-and-piston steam engine, but his scheme was unworkable, because he proposed to use one vessel as both boiler and cylinder.

	The Galileo Project
		From a Huguenot family; Papin's life was greatly influenced by the revocation of the Edict of Nantes, which kept him in exile, though he had already left France, possibly because of the increasing restrictions that were the prelude to the revocation.
		Charles-Auguste, Landgrave of Hesse-Kassel, appointed Papin Professor of Mathematics at University of Marburg, 1687-95.
		Whatever the father's status, Papin received no patrimony and was utterly dependent on patronage all his life, but as a refugee (and difficult man) he never got the position and security he needed.

	History of STEAM (Site not responding. Last check: 2007-10-16)
		By 1690 Papin is professor of mathematics at the university of Marburg.
		Papin's machine is extremely leisurely because he uses the same container as both boiler and cylinder.
		Though probably unaware of this, they are combining two elements pioneered separately by Denis Papin and Thomas Savery - Papin's piston and Savery's separation of the boiler (providing the supply of steam) from the cylinder (where the steam does its work).

	Denis Papin
		Denis Papin (August 22, 1647 - c.1712) was a French physicist, mathematician and inventor.
		Further, from a different source: Several of Papins' papers were put before the Royal Society between 1707 and 1712 without acknowledging or paying him, about which he complained bitterly.
		Papins ideas included a description from 20 years earlier of an atmospheric steam engine, the likes of which was built and put into use by Newcomen in 1712, coincidentally thought to be the year of Papins death.

	Capsule Pipelines - History - Early Developments
		Denis Papin is widely attributed with the presentation of a paper entitled the 'Double Pneumatic Pump' to the Royal Society of London in 1667 [1/2].
		All the available evidence suggests this is inaccurate, although Denis Papin, Christiaan Huygens, Robert Hooke and Robert Boyle were all involved in early experiments with pneumatics between 1660 and 1690 [A].
		[A] Denis Papin was born in Blois, France on 22 August 1647 [13].

	Leibniz, Papin and the Steam Engine
		Although Papin's immediate motive was, as he wrote to Huygens, "to relieve poverty, and to get wholesome and agreeable foods from things that we ordinarily reject as useless," his digester was also a major advance toward the steam engine, because of a totally new feature -the safety valve.
		With this discovery, Papin was prepared to initiate a qualitative technological advance -not a linear extrapolation from his 1690 results, such as building larger atmospheric engines, but a proposal to directly harness the violent force of the expanding steam.
		Papin's 1707 "Proposition" was thus the last heard of any practical plan for a steamship or for early application of steam power, besides pumping mines, until the intervention of Benjamin Franklin's networks in England later in the century.

	Denis Papin
		Denis Papin, one of the inventors of the steam-engine, was a native of Blois, where he was born on the 22nd of August 1647.
		Shortly after the publication of the Expériences, Papin, who had crossed to London, was hospitably received by Robert Boyle, whom he assisted in his laboratory and with his writings.
		At Münden, however, the vessel was confiscated at the instance of the boatmen, who objected to the invasion of their exclusive privileges in the Weser navigation.
