John Tyndall

Born 2 Aug 1820; died 4 Dec 1893 at age 73. Irish physicist who demonstrated why the sky is blue. He became known to the scientific world in 1848 as the author of a substantial work on Crystals. In 1856 he traveled with Professor Huxley to Switzerland, after which he co-authored On the Structure and Motion of Glaciers. He also published Heat as a Mode of Motion (1863), On Radiation (1865), followed by Sound, then in 1870 he published Light. Included in these works were studies of acoustic properties of the atmosphere and the blue colour of the sky, which he suggested was due to the scattering of light by small particles of water. His initial scientific reputation was based on a study of diamagnetism. He carried out research on radiant heat, studied spontaneous generation and the germ theory of disease, glacier motion, sound, the diffusion of light in the atmosphere and a host of related topics. He showed that ozone was an oxygen cluster rather than a hydrogen compound, and invented the firemans respirator and made other less well-known inventions including better fog-horns. One of his most important inventions, the light pipe, has led to the development of fibre optics. The modern light instrument is known as the gastroscope, which enables internal observations of a patient's stomach without surgery. Tyndall was a very popular lecturer.
