Robert Wilhelm Eberhard Bunsen (30see below 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 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. 羅伯特·威廉·本生（Robert Wilhelm Bunsen，1811年3月31日－1899年8月10日），德國化學家。輻射元素銫和銣的發現者，本生燈以他命名，此外他研究了熱體的電磁波譜。
