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.

Robert Wilhelm Bunsen (March 30, 1811-August 16, 1899) was a German chemist.
After his return to Germany, Bunsen became a lecturer at Göttingen and began experimental studies of the (in)solubility of metal salts of arsenious acid[?].
For that purpose, Bunsen developed a special gas burner in 1885 that was later named the "Bunsen burner".

Bunsen's studies of the composition of gases given off from blast furnaces showed that 50 to 80 percent or more of the heat was wasted and led to elaboration of his methods of measuring volumes of gases in his only publication, Gasometrische Methoden (1857).
Bunsen also invented the filter pump (1868), the ice calorimeter (1870), and the vapour calorimeter (1887).
Though he is generally credited with the invention of the Bunsen burner, he seems to have contributed to its development only in a minor way.

  Robert Wilhelm Von Bunsen - LoveToKnow 1911
ROBERT WILHELM VON BUNSEN (1811-1899), German chemist, was born at Gottingen on the 31st of March 1811, his father, Christian Bunsen, being chief librarian and professor of modern philology at the university.
The first research by which attention was drawn to Bunsen's abilities was concerned with the cacodyl compounds (see Arsenic), though he had already, in 1834, discovered the virtues of freshly precipitated hydrated ferric oxide as an antidote to arsenical poisoning.
Bunsen founded no school of chemistry; that is to say, no body of chemical doctrine is associated with his name.

Robert Wilhelm Bunsen (March 30, 1811-August 16, 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 developed a special gas burner in 1885 that was later named the "Bunsen burner".

 Bunsen
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 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 had become interested in the chemical properties of alkali metals, such as barium and sodium.

 Robert Wilhelm Eberhard Bunsen Biography | World of Chemistry
The son of a university professor, Bunsen graduated from the Gymnasium at Holzminden in 1828.
Bunsen and Kirchhoff knew that the key to analyzing incandescent light was to view it through a spectroscope, a device that split the light into its component colors.
However, the spectra produced from Bunsen and Kirchhoff's initial experiments were tainted: light from the gas burner used to heat the specimens to incandescence would creep into the beam, skewing the spectrum.

Also while at Marsburg, Bunsen developed techniques that could reduce the loss of certain valuable gases and by-products used in furnaces, from which nearly half the heat was lost previously.
In 1841, Bunsen developed a carbon electrode, which was an important part of the "Bunsen battery," used in electroplating.
Bunsen's contribution was the idea to mix gas and air before the flame is lit, which is important in getting the flame to the high temperature that Kirchoff needed for his experiments.
