Bunsen at the University of Marburg in Germany, earning his doctorate in 1851. Member of the Royal Society of London (1852) and professor at the Royal Institution (53). Known for his research on the scattering of light by large molecules and small particles (the Tyndall phenomenon), he elucidated the mechanism behind why the sky appears blue. He also studied the magnetic properties of crystals, the heat absorption and radiation of gases, and is famous for confirming that food does not spoil in sterile air, thus dispelling the theory of spontaneous generation. Contributed to the popularization of science. His main work was Heat Considered As a Mode of Motion (63). Tyndall |
