Google Celebrating 200th Birthday of Robert Bunsen a German Chemist - Google Doodle Logo on 31st March, 2011

Robert Wilhelm Eberhard Bunsen (30 March 1811 – 16 August 1899)[1] was a German chemist. He investigated emission spectra of heated elements, and with Gustav Kirchhoff discovered caesium (in 1860) and rubidium (in 1861). 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. The Robert Wilhelm Bunsen Medal is assigned every year by the European Geosciences Union ( to scientists who provided significant advance in the fields of Geochemistry, Mineralogy, Petrology, and Volcanology.
