Robert Bunsen is born in Göttingen, Germany. Bunsen goes on to investigate emission spectra of heated elements and is credited with the discoveries of caesium (in 1860) and rubidium (in 1861). He is perhaps most well known for his development of the Bunsen burner, an improvement on the laboratory burners then in use. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.
