Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January
1943) was a Serbian-American[2][3][4] inventor, electrical
engineer, mechanical engineer, physicist, and futurist who is best
known for his contributions to the design of the modern alternating
current (AC) electricity supplysystem.[5]
Born and raised in the Austrian Empire, Tesla received an advanced
education in engineering and physics in the 1870s and gained
practical experience in the early 1880s working in telephony and at
Continental Edison in the new electric power industry. He immigrated to
the United States in 1884, where he would become a naturalized
citizen. He worked for a short time at the Edison Machine Works in New
York City before he struck out on his own. With the help of partners to
finance and market his ideas, Tesla set up laboratories and companies
in New York to develop a range of electrical and mechanical devices.
His alternating current(AC) induction motor and related polyphaseAC
patents, licensed by Westinghouse Electricin 1888, earned him a
considerable amount of money and became the cornerstone of the
polyphase system which that company would eventually market.
Attempting to develop inventions he could patent and market, Tesla
conducted a range of experiments with mechanical
oscillators/generators, electrical discharge tubes, and early X-ray
imaging. He also built a wireless-controlled boat, one of the first ever
exhibited. Tesla became well known as an inventor and would
demonstrate his achievements to celebrities and wealthy patrons at
his lab, and was noted for his showmanship at public lectures.
Throughout the 1890s, Tesla would pursue his ideas for wireless
lighting and worldwide wireless electric power distribution in his high-
voltage, high-frequency power experiments in New York and Colorado
Springs. In 1893, he made pronouncements on the possibility
of wireless communication with his devices. Tesla tried to put these
ideas to practical use in his unfinished Wardenclyffe Tower project, an
intercontinental wireless communication and power transmitter, but
ran out of funding before he could complete it.[6]
After Wardenclyffe, Tesla went on to try and develop a series of
inventions in the 1910s and 1920s with varying degrees of success.
Having spent most of his money, he lived in a series of New York
hotels, leaving behind unpaid bills. The nature of his earlier work and
the pronouncements he made to the press later in life earned him the
reputation of an archetypal "mad scientist" in American popular culture.
[7] Tesla died in New York City in January 1943.[8] His work fell into
relative obscurity following his death, but in 1960, the General
Conference on Weights and Measures named the SI unit of magnetic flux
density the tesla in his honor.[9] There has been a resurgence in
popular interest in Tesla since the 1990s.[10]
