About Robert Bunsen
Robert Wilhelm Eberhard Bunsen 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. In 1841, Bunsen created the Bunsen cell battery, using a carbon electrode instead of the expensive platinum electrode used in William Robert Grove's electrochemical cell. Bunsen was the youngest of four sons of the University of Göttingen's chief librarian and professor of modern philology, Christian Bunsen (1770–1837). During his journeys, Bunsen met the scientists Friedlieb Runge (who discovered aniline and in 1819 isolated caffeine), Justus von Liebig in Giessen, and Eilhard Mitscherlich in Bonn.
