"Robert Wilhelm Eberhard Bunsen (/ˈbʌnsən/; German: [ˈbʊnzən]; 30 March 1811[a] – 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 for spectroscopy is named after Bunsen and Kirchhoff." - (en.wikipedia.org 10.11.2019)
