He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. Bunsen developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organoarsenic chemistry. With his laboratory assistant, Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff. ==Early life and education== Robert Bunsen was born at Göttingen in 1811, in what is now the state of Lower Saxony in Germany. Bunsen was the youngest of four sons of the University of Göttingen's chief librarian and professor of modern philology, Christian Bunsen (1770–1837). Sources disagree on Robert Bunsen's exact birth date. His parish register, as well as two ''curricula vitae'' handwritten by Bunsen himself, support the claim that 30 March 1811 is Bunsen's true birth date;〔''Robert Wilhelm Bunsens Korrespondenz vor dem Antritt der Heidelberger Professur (1852): kritische Edition''; Christine Stock, () Stuttgart: Wissenschaftliche Verlagsgesellschaft, 2007. ISBN 3-8047-2320-9〕〔("Robert Wilhelm Bunsen" ), ''Encyclopædia Britannica''. ''Encyclopædia Britannica Online''. ''Encyclopædia Britannica'', 2011. Web. 3 April 2011〕〔Georg Lockemann: ''Robert Wilhelm Bunsen. Lebensbild eines deutschen Naturforschers'', Wissenschaftliche Verlagsgesellschaft Stuttgart, 1949, p. 18〕 however, many later sources cite 31 March as the date.〔〔("Robert Bunsen's 200th Anniversary" ), Royal Society of Chemistry〕〔("Bunsen without his burner" ), Colin A. Russell, ''Phys. Educ.'' 34(5) September 1999〕〔("Bunsen, Robert Wilhelm Eberhard ), ''Complete Dictionary of Scientific Biography'' (2008). Retrieved 31 March 2011 from Encyclopedia.com〕 According to his biographer Georg Lockemann, Bunsen himself celebrated his birthday on the 31st in his later years. Lockemann nevertheless regarded the 30th as the correct date.〔 After attending school in Holzminden, Bunsen matriculated at Göttingen in 1828 and studied chemistry with Friedrich Stromeyer as well as mineralogy with Johann Friedrich Ludwig Hausmann and mathematics with Carl Friedrich Gauss.〔 After obtaining a PhD in 1831, Bunsen spent 1832 and 1833 traveling in Germany, France, and Austria; Friedlieb Runge (who discovered aniline and in 1819 isolated caffeine), Justus von Liebig in Giessen, and Eilhard Mitscherlich in Bonn were among the many scientists he met on his journeys.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Robert Bunsen」の詳細全文を読む スポンサード リンク
