[[File:Robert Wilhelm Bunsen (HeidICON 53016) (cropped).jpg|thumb|right|Robert Bunsen]] '''Robert Wilhelm Eberhard Bunsen''' (30 March 1811 – 16 August 1899) was a [[Germany|German]] [[chemist]]. He improved the [[bunsen burner]] which now has his name. It was invented by [[Michael Faraday]]. Much more important was the work he did which led to [[spectroscopy]]. Together with [[Gustav Kirchhoff]], he developed a method of using the [[spectrum]] of light to identify the composition of [[solid]]s,[[liquid]]s or [[gas]]es. Spectroscopy originated through the study of visible light dispersed according to its wavelength, for example, by a [[prism]]. Bunsen found the elements [[caesium]] and [[rubidium]] with his [[spectroscope]].<ref>{{cite web |url= http://www.rsc.org/chemsoc/visualelements/pages/data/rubidium_data.html |title=Visual elements: Rubidium |first= |last=|work=rsc.org |year=2011 |accessdate=26 June 2011}}</ref> In 1841, Bunsen developed the [[Bunsen cell]], by improving the [[Chemical cell|galvanic cell]] [[William Grove]] had developed in 1839. ==References== {{reflist}} {{bio-stub}} {{DEFAULTSORT:Bunsen, Robert Wilhelm}} [[Category:German chemists]] [[Category:1811 births]] [[Category:1899 deaths]]
