	Ingenhousz, Jan
		Jan Ingenhousz was a pioneer in plant physiology and demonstrated that oxygen is produced during photosynthesis.
		Born in the Netherlands, Ingenhousz practiced medicine in several European countries and served as a court physician to Empress Maria Theresa of Austria for twenty years.
		Ingenhousz used the gas-measuring techniques of his friend Joseph Priestley to study how plants alter the air.

		Jan Ingenhousz or Ingen-Housz (December 8, 1730 - September 7, 1799) was a Dutch-born British physiologist, botanist and physicist.
		Jan Ingenhousz was born on Dec. 8, 1730, in Breda.
		Ingenhousz also opposed the theory of subtle electrical fluids and repeated some of the experiments on plant electricity to disprove the accepted view that positive electricity was good for the growth of plants and that negative electricity retarded it.

	Biography: Jan Ingenhousz - ChemgaPedia
		In London, Ingenhousz was an early champion of the inoculation against smallpox by taking small amounts of the live, unmodified virus from patients with mild cases of the disease.
		Ingenhousz carried out a series of experiments to prove that the bubbles were independent of heat and that the cause of this phenomenon must be light.
		Ingenhousz's work, Experiments On Vegetables, Discovering their Great Power of Purifying the Common Air in Sunshine, and of Injuring it in the Shade or at Night, 1779, laid the foundations for the study of photosynthesis.

	Scientist and Inventor: Benjamin Franklin: In His Own Words... (AmericanTreasures of the Library of Congress)
		Benjamin Franklin's formulation of a general theory of electrical "action" won him an international reputation in pure science in his own day.
		Writing to Dutch physician and scientist Jan Ingenhousz, Franklin responds to a number of his friend's questions about electricity and the Leyden jar, an early form of electrical condenser.
		In this lengthy essay intended for his fellow scientist Jan Ingenhousz, Benjamin Franklin attempted to explain the effects of lightning on a church steeple in Cremona, Italy, by describing the effects of electricity on various metals.

	Photosynthesis: Discovery Milestones
		Jan Baptista van Helmont, Flemish physician, chemist, and physicist, in the 1600s carried out a famous experiment by growing a willow tree in a pot for five years.
		Ingenhousz was mistaken in believing that the oxygen made by plants came from carbon dioxide.
		However, Jan Ingenhousz was the first person to show that light is essential to the plant process that somehow purifies air fouled by candles or animals.

	Ingenhousz, Jan
		Ingenhousz was born in Breda and studied at Louvain and Leiden and abroad at Paris and Edinburgh, after which he set up a private medical practice in Breda.
		In 1768 he was sent to the Austrian court by George III, to inoculate the royal family, and became court physician there 1772-79.
		Apart from studying plants, Ingenhousz developed in 1776 an improved apparatus for generating large amounts of electricity; he also invented a hydrogen-fuelled lighter to replace the tinderbox, and investigated the use of an air and ether vapour mixture as a propellant for an electrically fired pistol.

	Project Ingenhousz
		Capitalizing on its leading position in photosynthesis and related fields and consistent with its abundance of solar radiation, Arizona State University is poised to expand and broaden this area of excellence in a University-wide initiative.
		Jan Ingenhousz (1730-1799), a Dutch physiologist, was one of the first scientists to investigate photosynthesis.
		Jan Ingenhousz demonstrated that plants take in carbon dioxide and release oxygen when exposed to light.

		Ingenhousz war ein Verfechter der - bereits von Mary Wortley Montagu propagierten - Pockenschutzimpfung; er entnahm Patienten, die an einer milden Form der Pocken erkrankt waren, Serum (mit noch lebenden Viren) und „inokulierte“ damit noch nicht erkrankte Personen.
		Ingenhousz führte daraufhin nach seiner Rückkehr aus Wien 1779 umfangreiche Versuchsreihen durch.
		Ingenhousz stellte auch eine Reihe von Versuchen an zur elektrischen Leitfähigkeit unterschiedlicher Materialien und zum Magnetismus.

	No. 2192: Franklin and Balloons
		Ingenhousz had responded to the first letter with a several questions about that second ascent.
		Next, he tells Ingenhousz, it's too bad so many rulers fail to take balloons seriously, because it'd be impossible to defend against an attack of steerable balloons.
		Ingenhousz had also suggested that British nationalism might be what had kept then from developing their own balloons.

	Biografia de Jan Ingenhousz
		(Johannes o Jan Ingenhousz; Breda, 1730 - Bowood, 1799) Fisiólogo y químico holandés, descubridor del proceso de la fotosíntesis en vegetales, por el cual las plantas, en presencia de luz, elaboran sustancias orgánicas a partir de otras sustancias inorgánicas, y liberan oxígeno a la atmósfera durante el proceso.
		Después de su estancia en Austria regresó a Londres, y aquí Ingenhousz comenzó a interesarse por el oxígeno producido por las plantas.
		Ingenhousz ideó una serie de procedimientos y realizó cientos de experimentos para medir la cantidad de oxígeno consumida y desprendida por las plantas en el proceso de respiración, y en 1779 demostró que las plantas eliminan dióxido de carbono (CO2) en la oscuridad.

	Chemistry of Life: Faces—The Human Dimension
		Jan Ingenhousz was born in Breda, Netherlands, and was a physician by trade.
		Joseph Priestley had earlier shown that plants could restore the ability of the air in the jar to support a flame or keep animals alive, but it was Ingenhousz who observed that plants only had this effect when exposed to light.
		For elucidating this cycle, Ingenhousz is considered the discoverer of photosynthesis.

	The Reactions of Photosynthesis (Site not responding. Last check: )
		Priestley concluded that plants release oxygen and use carbon dioxide.
		Ingenhousz found that the effects observed in Priestley’s experiment only occurred in the light.
		Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into oxygen and high energy sugars.
