Who Invented Electricity ?
From the writings of Thales of Miletus it appears that Westerners knew as long ago as 600 B.C. that amber becomes charged by rubbing. There was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances . As a result, Gilbert is called the father of modern electricity.
In 1660 Otto von Guericke invented a crude machine for producing static electricity. Francis Hauksbee, made improvements with static electricity. Today's highly developed descendant of these early machines is the Van de Graaf generator. Robert Boyle realized that attraction and repulsion were mutual and that electric force was transmitted through a vacuum. Stephen Gray distinguished between conductors and nonconductors. C. F.
