DEAD: ON THIS DATE

Robert Bunsen (aged 88)
German chemist

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 for spectroscopy is named after Bunsen and Kirchhoff.

DEATH: When Bunsen retired at the age of 78, he shifted his work solely to geology and mineralogy, interests which he had pursued throughout his career. He died in Heidelberg at the age of 88.
