Nikola Tesla

Nikola Tesla

Nikola Tesla (1856–1943) was a Serbian-American inventor and electrical engineer whose work on alternating current helped shape the modern electric power system. Born in Smiljan, in present-day Croatia, he studied engineering in Graz and emigrated to the United States in 1884, where he worked briefly for Thomas Edison before setting out on his own. His turning point came with his induction motor and polyphase alternating-current system, patented in 1888 and licensed to the industrialist George Westinghouse. The system lit the 1893 World's Columbian Exposition in Chicago and was adopted for the hydroelectric power plant at Niagara Falls, showing that electricity could be transmitted efficiently over long distances. He also invented the Tesla coil and made pioneering contributions to wireless transmission and radio technology. The SI unit of magnetic flux density, the tesla, is named in his honor.

Pioneers of Electricity and Communication

Samuel Morse developed a practical electric telegraph and the code that bears his name, while Michael Faraday discovered electromagnetic induction, the principle behind the electric generator. James Clerk Maxwell united electricity, magnetism and light in a single theory. Thomas Edison, who began his career as a telegraph operator, developed a practical incandescent light bulb, and Nikola Tesla pioneered alternating-current power systems.
