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 ]
The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements, is a 2010 book by science reporter Sam Kean. The book was first published in hardback on July 12, 2010, through Little, Brown and Company and was released in paperback on June 6, 2011, through Little, Brown and ...
The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", [1] and has since been awarded 140 times. [1] The medal is awarded annually and, unlike other Royal Society medals (such as the Hughes ), has been awarded without interruption since its inception.
Spectroscope of Kirchhoff and Bunsen. The systematic attribution of spectra to chemical elements began in the 1860s with the work of German physicists Robert Bunsen and Gustav Kirchhoff, [30] who found that Fraunhofer lines correspond to emission spectral lines observed in laboratory light sources. This laid way for spectrochemical analysis in ...
Bunsen's first name is derived from Robert Bunsen, after whom the Bunsen burner was named. His last name is a reference to the honeydew melon , which his head resembles, as well as to Honeywell Labs , a technology company which aired TV commercials ( "That someday is today ... at Honeywell" ) well-known at the time of The Muppet Show .
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 ...
The Bunsen–Kirchhoff Award is a prize for "outstanding achievements" in the field of analytical spectroscopy. It has been awarded since 1990 by the German Working Group for Applied Spectroscopy, and is endowed with €2500 by PerkinElmer, Germany. [1] [2] The prize is named in honor of chemist Robert Bunsen and physicist Gustav Kirchhoff.
