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
. 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
