Who was Nikola Tesla? "The pioneer of wireless signal"

  Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American[2][3][4] inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electrical supply system.[5]

Tesla started working in the telephony and electrical fields before immigrating to the United States in 1884 to work for Thomas Edison. He soon struck out on his own with financial backers, setting up laboratories/companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla as a consultant to help develop an alternating current system. 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 of radio communication,[6] for his X-ray experiments, and for his ill-fated attempt at intercontinental wireless transmission in his unfinished Wardenclyffe Tower project.[7]

Tesla's achievements and his abilities as a showman demonstrating his seemingly miraculous inventions made him world-famous.[8] Although he made a great deal of money from his patents, he spent a lot on numerous experiments over the years. In the last few decades of his life, he ended up living in diminished circumstances as a recluse in Room 3327 of New Yorker Hotel, occasionally making unusual statements to the press.[9][10][11] 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".[12][13] Tesla died penniless and in debt on 7 January 1943.[14][15][16][17]

Tesla's work fell into relative obscurity after his death, but since the 1990s, his reputation has experienced a comeback in popular culture.[18] 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.[19] His work and reputed inventions are also at the center of many conspiracy theories and have also been used to support various pseudosciences, UFO theories and New Age occultism.
In 1960, in honor of Tesla, the General Conference on Weights and Measures for the International System of Units dedicated the term "tesla" to the SI unit measure for magnetic field strength.[20]

Here are some of Tesla invention

RadioTesla's theories on the possibility of the transmission by radio waves go back as far lectures and demonstrations in 1893 in St. Louis, Missouri, the Franklin Institute in Philadelphia, Pennsylvania, and the National Electric Light Association.[104] Tesla's demonstrations and principles were written about widely through various media outlets.[85] Many devices such as the Tesla Coil were used in the further developement of radio.[6]
Tesla's radio wave experiments in 1896 were conducted in Gerlach Hotel (later renamed The Radio Wave building), where he resided.[105]
In 1898, Tesla demonstrated a radio-controlled boat (U.S. Patent 613,809Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles).
In 1898, Tesla demonstrated a radio-controlled boat—which he dubbed "teleautomaton"—to the public during an electrical exhibition at Madison Square Garden.[1] The crowd that witnessed the demonstration made outrageous claims about the workings of the boat: everything from magic and telepathy to being piloted by a trained monkey hidden inside.[106] Tesla tried to sell his idea to the U.S. military as a type of radio-controlled torpedo, but they showed little interest.[107] Remote radio control remained a novelty until World War I and afterward, when a number of countries used it in military programs.[citation needed]

In 1900, Tesla was granted patents for "system of transmitting electrical energy" and "an electrical transmitter". When Guglielmo Marconi made his famous first ever transatlantic radio transmission in 1901, Tesla quipped that it was done with 17 Tesla patents. This was the beginning of years of patent battles over radio with Tesla's patents being upheld in 1903, followed by a reverse decision in favor of Marconi in 1904. In 1943, a Supreme Court of the United States decision restored the prior patents of Tesla, Oliver Lodge, and John Stone.[108] The court declared that their decision had no bearing on Marconi's claim as the first to achieve radio transmission, just that since Marconi's claim to certain patents were questionable, he could not claim infringement on those same patents[109] (there are claims the high court was trying to nullify a World War I claim against the U.S. government by the Marconi Company via simply restoring Tesla's prior patent).[108]

Later in life, Tesla made claims concerning a "teleforce" weapon after studying the Van de Graaff generator.[147][148] The press called it a "peace ray" or death ray.[149][150] Tesla described the weapon as being able to be used against ground based infantry or for antiaircraft purposes.
Tesla gives the following description concerning the particle gun's operation:
[The nozzle would] send concentrated beams of particles through the free air, of such tremendous energy that they will bring down a fleet of 10,000 enemy airplanes at a distance of 200 miles from a defending nation's border and will cause armies to drop dead in their tracks.[151][152]

The list of credits given to Nikola Tesla is large indeed. He has been associated with:
  • cosmic rays
  • radar
  • diathermy
  • the high-frequency furnace
  • wave-guide for microwave transmission
  • space navigation code
  • cryogenic engineering
  • electrotherapeutics
  • energy transmission to satellites
  • principles of solid state transistor technology
  • the reciprocating dynamo
