Charles de Coulomb (1736-1806), French physicist, pioneer in electrical theory, born in Angoulême. He served as a military engineer for France in the West Indies, but retired to Blois, France, at the time of the French Revolution to continue research in magnetism, friction, and electricity. In 1777 he invented the torsion balance for measuring the force of magnetic and electrical attraction. With this invention, Coulomb was able to formulate the principle, now known as Coulomb's law, governing the interaction between electric charges. In 1779 Coulomb published the treatise Théorie des machines simples (Theory of Simple Machines), an analysis of friction in machinery. After the revolution Coulomb came out of retirement and assisted the new government in devising a metric system of weights and measures. The unit of quantity used to express electrical charge, the coulomb, was named after him.
