Nikola Tesla

   Nikola Tesla ( 10 July 1856 – 7 January 1943) was a Serbian American Inventor, physicst,mechanical engineer, electrical engineer and futurist. He was an important contributor to the use of commerical electricity and is best known for developing the modern alternating current (AC) electrical supply system. His many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries were based on the theories of electromagnetic technology discovered by Michael Faraday. Teslas’s parents and theoretical work also formed the basis of wireless communication and the radio.Born to Serbian parents in the village of Smiljan  (now part of Gospic, present day Croatia), Tesla was a subject of the Austrian Empire by birth and later became an American citizen.Because of his 1894 demonstration of short range wireless communication through radio and his eventual victory in the “War of Currents”, he was widely respected as one of the greatest electrical engineers who worked in America. He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. In the United States during this time, Tesla’s fame rivaled that of any other inventor or scientist in history or popular culture. Tesla demonstrated wireless energy transfer to power electronic devices in 1891, and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project.
      In the end of his life in the 1930s, Tesla became reclusive, living alone in a New York City hotel room and only appearing occasionally to make unusual statements to the press. 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”. He died penniless and in debt in January, 1943.Tesla’s work fell into relative obscurity after his death, but since the 1990s, his reputation has experienced a popular culture comeback. In 2005, he was listed amongst the top 100 nominees in the TV show “The Greatest American”, an open access popularity poll conducted by AOL and The Discovery Channel.  
  Briefly worked with Thomas Edison before the two parted ways.He died on January 7, 1943, in New York City.He sold several patent rights, including those to his alternating-current machinery, to George Westinghouse. His 1891 invention, the Tesla coil, is used in radio technology. The SI unit measuring magnetic field B (magnetic flux / intensity / induction), the TESLA , was named in his honor.
