Nikola Tesla

Nikola Tesla (1856–1943) was an inventor and electrical engineer whose work helped shape modern systems for generating, transmitting and using electricity. Born in Smiljan, in the Austrian Empire, he studied engineering in Graz and later worked in Budapest and Paris. In 1884, he moved to the United States and joined the company of Thomas Edison for a short period before pursuing his own projects. Tesla became particularly interested in alternating current, or AC, which changes the direction of electric flow periodically.

He developed important motors, generators and other electrical devices based on rotating magnetic fields. His induction motor and polyphase AC system became central technologies in the development of practical electrical power networks. In the late 1880s, Tesla worked with industrialist George Westinghouse, whose company helped develop and commercialize AC technology in the United States. Tesla continued experimenting with high-frequency currents, wireless communication, lighting and other electrical technologies.

In the 1890s, he demonstrated spectacular experiments with high-voltage alternating currents and helped popularize fluorescent and gas-discharge lighting concepts. He also conducted early experiments related to radio transmission and remote control, although the development of radio involved several inventors and scientists. Tesla's most ambitious project was the Wardenclyffe Tower on Long Island, intended to explore wireless communication and the transmission of electrical energy.

The project was never completed as originally planned and was dismantled in 1917. Tesla received numerous patents during his career, but many of his later projects struggled to attract sustained financial support. He spent his final years in New York and died in 1943. Today, his contributions to alternating-current systems, electric motors and electrical engineering remain an important part of the history of modern technology.
