Robert Wilhelm Bunsen
(1811–1899)
Direktor des Chemischen Laboratoriums
der Universität Heidelberg von 1852 bis 1889
1855 als modernstes Chemie-Laboratorium Europas eröffnet, war dieser Bau ganz auf Bunsens anorganisch-analytische Arbeiten zugeschnitten. Seine methodischen und apparativen Innovationen machten Bunsen zum Wegbereiter der physikalischen Chemie. Mehr als 3000 Studierende aus aller Welt erlernten hier seine gasometrischen Verfahren und die gemeinsam mit Gustav Kirchhoff 1859/60 entwickelte Spektralanalyse: Mit dieser entdeckten beide die Elemente Caesium (1860) und Rubidium (1861).
Enthüllt am 12. Oktober 2011. Im 200. Geburtsjahr Robert Wilhelm Bunsens und im 625. Gründungsjahr der Universität Heidelberg.

Robert Wilhelm Eberhard Bunsen (30 March 1811 – 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. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.(Submitted on February 27, 2026, by James Hulse of Medina, Texas.)
Bunsen also developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organic arsenic chemistry. With his laboratory assistant Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use.
