Robert Bunsen's 202nd Birthday.

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 Gustav Kirchhoff. Bunsen developed several gas-analytical methods.. He 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 Bunsen burners are still being used in labs, across the world.
