Nikola TeslaÂ was aÂ Serbian born and later Â inventor,Â electrical engineer,Â mechanical engineer,Â physicist, andÂ futuristÂ best known for his contributions to the design of the modernalternating currentÂ (AC)Â electricity supplyÂ system.
Tesla gained experience inÂ telephonyÂ and electrical engineering before emigrating to theÂ United StatesÂ in 1884 to work forÂ Thomas Edison. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented ACÂ induction motorÂ and transformer were licensed byÂ George Westinghouse, who also hired Tesla as a consultant to help develop aÂ power systemÂ usingÂ alternating current. Tesla is also known for his high-voltage, high-frequency power experiments in New York and Colorado Springs which included patented devices and theoretical work used in the invention ofÂ radioÂ communication,Â Â for his X-ray experiments, and for his ill-fated attempt at intercontinental wireless transmission in his unfinishedÂ Wardenclyffe TowerÂ project.
Tesla’s achievements and his abilities as a showman demonstrating his seemingly miraculous inventions made him world-famous.Â Â Although he made a great deal of money from his patents, he spent a lot on numerous experiments. He lived for most of his life in a series of New York hotels although the end of his patent income and eventual bankruptcy led him to live in diminished circumstances.Â Tesla still continued to invite the press to parties he held on his birthday to announce new inventions he was working and make (sometimes unusual) statements.Â Â Because of his pronouncements and the nature of his work over the years, Tesla gained a reputation in popular culture as the archetypal “mad scientist”.Â Â He died in room 3327 of theÂ New Yorker HotelÂ on 7 January 1943.
Tesla’s work fell into relative obscurity after his death, but since the 1990s, his reputation has experienced a comeback inÂ popular culture.Â His work and reputed inventions are also at the center of manyÂ conspiracy theoriesÂ and have also been used to support variouspseudosciences,Â UFOÂ theories andÂ New AgeÂ occultism. In 1960, in honor of Tesla, theÂ General Conference on Weights and MeasuresÂ for theInternational System of UnitsÂ dedicated the term “tesla” to the SI unit measure forÂ magnetic fieldÂ strength.
