	ROBERT WILHELM BUNSEN
		Bunsen was born on March 31, 1811 in Göttingen, Germany, the youngest of four sons.
		In 1836, Bunsen was nominated to succeed Wöhler at Kassel.
		Bunsen's habit was to assign a scientific task to his students and then to work with a student only as long as required to reach some measure of independence.

	Robert Bunsen - Wikipedia, the free encyclopedia
		Robert Wilhelm Bunsen (31 March 1811 – 16 August 1899) was a German chemist.
		In 1841, Bunsen created a carbon electrode that could be used instead of the expensive platinum electrode used in Grove's battery.
		For that purpose, Bunsen (or his laboratory assistant Peter Desdega) had in 1855 perfected a special gas burner, invented by the scientist Michael Faraday, that was later named the "Bunsen burner".

		Ironically, Bunsen will be remembered by generations of chemistry students for a mere improvement in a burner, when his other contributions to the field of chemistry are vastly more significant and diverse, covering such areas as organic chemistry, arsenic compounds, gas measurements and analysis, the galvanic battery, elemental spectroscopy and geology.
		Bunsen himself described one of these compounds: "the smell of this body produces instantaneous tingling of the hands and feet, and even giddiness and insensibility...It is remarkable that when one is exposed to the smell of these compounds the tongue becomes covered with a fl coating, even when no further evil effects are noticeable."
		Bunsen's daring experiments showed that cacodyl was an oxide of arsenic that contained a methyl radical (a group of atoms acting as one species).

		Robert Wilhelm Bunsen (31 marzo 1811 - 16 agosto 1899) fu un chimico e fisico tedesco.
		Al suo ritorno in Germania Bunsen divenne lettore a Göttingen dove iniziò i suoi studi sperimentali sulla solubilità dei sali dell'acido arsenioso.
		Nel 1841 Bunsen creò un elettrodo di carbonio da usare al posto del costoso elettrodo di platino nella pila di Grove.

		Robert Bunsen was born on March 31, 1811 in Göttingen, Germany, the youngest of four sons.
		The Bunsen burner consists of a metal tube on a base with a gas inlet at the lower end of the tube, which may have an adjusting valve; openings in the sides of the tube can be regulated by a collar to admit as much air as desired.
		Bunsen also invented the filter pump (1868), the vapour calorimeter (1887) and grease-spot photometer used to compare intensity of similar light sources (1844), a new valve, Bunsen-effuser (determines gas density by velocity measurement of gas drain through a small hole).

		ROBERT W. Robert Wilhelm Bunsen is probably best known for the laboratory gas burner which bears his name, though in fact, it was probably developed by his laboratory technician, Robert Desdega.
		Bunsen’s first important work was in the area of organic chemistry, where he studied the reactions of cacodyl, an organometallic compound of arsenic.
		Use of the latter in conjunction with a glass prism led to the development of the Bunsen spectroscope in collaboration with the German physicist Gustav Kirchoff and to the spectroscopic discovery of the elements rubidium and cesium.

	Robert Bunsen Biography (1811-1899)
		Robert Bunsen is best known for his invention of the improved gas flame device which bears his name: the Bunsen burner.
		However, Robert Wilhelm Eberhard Bunsen's contributions to science extend far beyond this one invention; he developed a number of other common laboratory instruments, as well as a new device and process for analyzing the elemental constituents of chemicals called spectroscopy.
		Bunsen was again forced to invent equipment whose precision would match that of his own research.

		Together with Bunsen, he immediately discovered that the resulting spectrum had bright lines on a continuous background, that the pattern of lines was different for each element, and that some of these lines coincided with the dark lines of the solar spectrum.
		Bunsen noted that a mixture of air and gas burned at a higher temperature and with less luminosity than a pure gas flame.
		With this new instrument Bunsen and Kirchhoff quickly discovered two new elements, alkali metals they called "cesium" and "rubidium" for the Latin for the main colours of their spectral lines, blue and red respectively.

		Bunsen was working on cacodyl compounds, unpleasant and dangerous organic compounds of arsenic, until a laboratory explosion cost him the sight of one eye and he nearly died of arsenic poisoning.
		Using electrolysis, he was the first to isolate metallic magnesium and demonstrate the intense light it produces when burned in air.
		The Bunsen burner was probably used to heat metal salts for spectroscopic analysis, a technique which he pioneered, together with physicist Gustav Kirchhoff, and by which he discovered the new elements.

		While Bunsen invented or improved numerous pieces of laboratory equipment, the Bunsen burner was not his invention, but rather a laboratory tool he popularized to such an extent that it became linked to his name.
		Two inventions that were properly his and rightly bear his name are the Bunsen cell that converts chemical energy into electrical energy and the Bunsen photometer that measures the intensity of a light source.
		He was the first to obtain magnesium in the metallic state and study its physical and chemical properties, demonstrating the brilliance of the flame when magnesium is burned in air, an effect of later importance in photography.
