Myths and Rumors persist in the tale of legendary inventor Nikola Tesla
By David Jerale
There has been a great increase in the popularity of inventor Nikola Tesla in recent years; well deserved, as Tesla’s work helped shape the modern world. However, his return to the spotlight has brought with it fabricated or exaggerated claims about his achievements and intentions, some of the most persistent surrounding Tesla’s biggest failure: the Wardenclyffe tower.
Nikola Tesla was an inventor who obtained around 300 patents worldwide for his inventions. Some of Tesla’s patents are not accounted for, and various sources have discovered some that have lain hidden in patent archives. There are a minimum of 278 patents issued to Tesla in 26 countries that have been accounted for. Many of Tesla’s patents were in the United States, Britain, and Canada, but many other patents were approved in countries around the globe. Many inventions developed by Tesla were not put into patent protection. …more
Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success—unlike his early employer and chief rival, Thomas Edison.
Nikola Tesla’s Early Years
Nikola Tesla was born in 1856 in Smiljan, Croatia, then part of the Austro-Hungarian Empire. His father was a priest in the Serbian Orthodox church and his mother managed the family’s farm. In 1863 Tesla’s brother Daniel was killed in a riding accident. The shock of the loss unsettled the 7-year-old Tesla, who reported seeing visions—the first signs of his lifelong mental illnesses.
Tesla studied math and physics at the Technical University of Graz and philosophy at the University of Prague. In 1882, while on a walk, he came up with the idea for a brushless AC motor, making the first sketches of its rotating electromagnets in the sand of the path. Later that year he moved to Paris and got a job repairing direct current (DC) power plants with the Continental Edison Company. Two years later he immigrated to the United States.
Nikola Tesla and Thomas Edison
Tesla arrived in New York in 1884 and was hired as an engineer at Thomas Edison’s Manhattan headquarters. He worked there for a year, impressing Edison with his diligence and ingenuity. At one point Edison told Tesla he would pay $50,000 for an improved design for his DC dynamos. After months of experimentation, Tesla presented a solution and asked for the money. Edison demurred, saying, “Tesla, you don’t understand our American humor.” Tesla quit soon after.
Nikola Tesla and Westinghouse
After an unsuccessful attempt to start his own Tesla Electric Light Company and a stint digging ditches for $2 a day, Tesla found backers to support his research into alternating current. In 1887 and 1888 he was granted more than 30 patents for his inventions and invited to address the American Institute of Electrical Engineers on his work. His lecture caught the attention of George Westinghouse, the inventor who had launched the first AC power system near Boston and was Edison’s major competitor in the “Battle of the Currents.”
Westinghouse hired Tesla, licensed the patents for his AC motor and gave him his own lab. In 1889 Edison arranged for a convicted New York murderer to be put to death in an AC-powered electric chair—a stunt designed to show how dangerous the Westinghouse standard could be.
Buoyed by Westinghouse’s royalties, Tesla struck out on his own again. But Westinghouse was soon forced by his backers to renegotiate their contract, with Tesla relinquishing his royalty rights.
In the 1890s Tesla invented electric oscillators, meters, improved lights and the high-voltage transformer known as the Tesla coil. He also experimented with X-rays, gave short-range demonstrations of radio communication two years before Guglielmo Marconi and piloted a radio-controlled boat around a pool in Madison Square Garden. Together, Tesla and Westinghouse lit the 1891 World’s Columbian Exposition in Chicago and partnered with General Electric to install AC generators at Niagara Falls, creating the first modern power station.
Nikola Tesla’s Failures, Death and Legacy
In 1895 Tesla’s New York lab burned, destroying years’ worth of notes and equipment. Tesla relocated to Colorado Springs for two years, returning to New York in 1900. He secured backing from financier J.P. Morgan and began building a global communications network centered on a giant tower at Wardenclyffe, on Long Island. But funds ran out and Morgan balked at Tesla’s grandiose schemes.
Tesla lived his last decades in a New York hotel, working on new inventions even as his energy and mental health faded. His obsession with the number three and fastidious washing were dismissed as the eccentricities of genius. He spent his final years feeding—and, he claimed, communicating with—the city’s pigeons.
Tesla died in his room on January 7, 1943. Later that year the U.S. Supreme Court voided four of Marconi’s key patents, belatedly acknowledging Tesla’s innovations in radio. The AC system he championed and improved remains the global standard for power transmission.
George W. Damm suggests that Nikola Tesla incorporated acoustic resonant criteria in the design and modulation of his tower at Shoreham, Long Island. At first, this seems a bit farfetched, but a pause to check the dimensions of the tower’s components and their acoustic resonant frequencies reveals that they are well-matched to the earth’s electrical resonant frequencies. Tesla’s sensitivity to sound, vibration and light, and his early work with compressed air oscillator frequency control may have been combined in his last major project. …more
Tesla was born “at the stroke of midnight” with lightning striking during a summer storm. He was born to a Serbian family in Smiljan near Gospić, Lika, (the Military Frontier of Austria-Hungary, now in Croatia). The midwife commented, “He’ll be a child of the storm,” to which his mother replied, “No, of light.” Tesla was baptized in the Old Slavonic Church rite. His Baptism Certificate reports that he was born on June 28 (Julian calendar; July 10 in the Gregorian calendar) 1856, and christened by the Serbian orthodox priest, Toma Oklobdžija. …more
