	Geissler tube - Wikipedia, the free encyclopedia
		The tube was invented by the German glassblower Heinrich Geissler in 1857.
		Geissler tubes contain a combination of one of the following: rarefied (thinned) gasses such as neon, argon, or air, or conductive liquids or minerals.
		Geissler tubes have had a large impact on the development of such instruments as the x-ray tube, the Electrotachyscope, neon signs, mass spectrometry and some forms of the light bulb, all of which use related vacuum and discharge principles.

	Geissler (Site not responding. Last check: 2007-09-10)
		Heinrich Geissler was born in the village of Igelshieb, in the Rennsteig area of the Dukedom of Saxony-Meiningen.
		Heinrich Geissler's youth coincided with a flowering in interest in experimental natural sciences leading to a greater demand for laboratory apparatus, particularly hollow glassware, which was to catapult the craft of the glassblower from a cottage industry to a profession.
		Geissler's tubes are the predecessors to the modern neon and fluorescent tubes.

	Aargon Neon - "When Virtual Reality Is Not Enough" - History of Neon
		Geissler was born in the Saxe-Meiningen region of Germany in 1814 and was educated as a glass blower.
		Geissler also invented a mercury vacuum pump, a vaporimeter for measuring the alcoholic strength of wine, balances, a normal thermometer and an areometer.
		Geissler's activity was held back from further development by the limitations inherent in his storage-battery powered induction coil, his use of non-durable thin platinum wire electrodes (which would sputter away quickly as the tubes were used), and the lack of a source of stable inert gases.

		Born in the village of Igelshieb, in the Rennsteig area of the Dukedom of Saxony-Meiningen, Geissler is a well known figure in the history of scientific instruments since the descendants of his inventions - the Geissler tube and the mercury vacuum pump are still in use today.
		Geissler's father Georg was an innovative glass-blower and maker of instruments such as barometers and thermometers.
		Geissler, however, earned his living for a decade as a traveling instrument maker before settling and establishing a workshop in Bonn, a young university town with a demand for laboratory apparatus.

		Geissler was born into a family of craftsmen who were well versed in the art of glassworking: his grandfather was an accomplished glassmaker, his father was a maker of glass jewelry, and his brothers were glassblowers in Berlin and Amsterdam.
		Geissler began his own career in this field at an early age, and by his mid-twenties he had worked for several universities constructing glass devices for scientific instruments.
		Geissler's most important invention was an improved vacuum tube first described by Plücker in 1858, though Geissler himself claimed he had been constructing them since 1857.

	Heinrich Geissler
		Geissler opened a shop in Bonn in 1854 to make scientific apparatus and devised his mercury air pump in 1855.
		Among his other inventions were the vaporimeter and the Geissler tube, in which an electric current produces light when passed through a rarefied gas.
		It was one of Geissler's tubes that Julius Plücker used when he first observed cathode rays in 1859.

		Heinrich Geissler (May 26 1814 - January 24 1879) was a German physicist.
		Educated by his father as a glassblower and gifted for the design and engineering, Geissler is most remembered for the invention of sealed glass tubes (called Geissler tubes) from which he demonstrated with Julius Plucker emission of a bluish glow by exciting the gas with an induction coil.
		It was not uncommon for these tubes to display elaborate and artistic shapes, adding much to the optical effect.

		Heinrich Geissler (1814-1879) was a German inventor who devised a way to pump out a vessel to a higher vacuum than had ever been attained at the time.
		His sealed, evacuated glass tubes came to be known as Geissler tubes.
		Sir William Crookes (1832-1919) improved on Geissler's method of evacuating vessels and by 1875 achieved vacuums of about 1/100 mm of mercury.

		Caption: The Geissler tube is a generic name that is used for a huge variety of discharge tubes for which many of the names of their designers have long since been forgotten.
		Background: Geissler was the first person who was able to make this kind of tube because he improved upon an old idea called a mercury pump that had been invented in the 17th century.
		The electric discharge across this tube glows a faintly bluish violet colour characteristic a the tiny amount of mercury vapour left in the tube.
