Born 9 Apr 1770; died 10 Dec 1831 at age 61.
German physicist who discovered (1821) that an electric current flows between different conductive materials that are kept at different temperatures, known as the Seebeck effect. It is the basis of the thermocouple and is considered the most accurate measurement of temperature. It is also a key component of the semi-conductor, the foundation of the modern computer business. Seebeck's work was the basis of German physicist Georg Simon Ohm (1789-1854) discoveries in electricity and of French physicist Jean Charles Athanase Peltier (1785-1845), whose Peltier effect became well known as a way to use electricity to freeze water (air conditioning, refrigeration).
