birth Robert Bunsen Born 31 Mar 1811; died 16 Aug 1899 at age 88. Robert Wilhelm Eberhard Bunsen was a German chemist who, working with Gustav Kirchhoff, about 1859 observed that each element emits a light of characteristic wavelength. (These studies opened the field of spectrum analysis, important in the study of the Sun and stars.) With this tool, Bunsen soon discovered two new elements: caesium and rubidium. He developed several techniques used in separating, identifying, and measuring various chemical substances. He also made a number of improvements in chemical batteries for use in isolating quantities of pure metals, (one is known as the Bunsen battery). His Bunsen burner was created for use in flame tests of various metals and salts because its nonluminous flame did not interfere with the colored flame given off by the test material. |
