Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff . [ 11 ]
A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.
Robert Bunsen invented the now-famous Bunsen burner in 1855, which was useful in flame tests due to its non-luminous flame that did not disrupt the colors emitted by the test materials. [ 4 ] [ 1 ] The Bunsen burner , combined with a prism (filtering the color interference of contaminants ), led to the creation of the spectroscope , capable of ...

Name Rationale Notes 1877: Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "For their researches & discoveries in spectrum analysis" [8] 1878: Louis Paul Cailletet and Raoul Pictet "For their researches, conducted independently, but contemporaneously, on the condensation of the so-called permanent gases" [9] 1879: Paul Emile Lecoq de Boisbaudran
Bunsen was joined in his research by Gustav Kirchhoff. Kirchhoff used the concept of the dispersion of white light by a prism in the invention of the spectroscope, a device with a prism at its centre which split the light from Bunsen's flames into distinct bands of its constituent colours – the element's spectral lines.
