Biography
Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American electrical engineer, inventor, mechanical engineer, and physicist who changed the way electricity was generated, transmitted, and used worldwide with his work on alternating current systems. He was born in Smiljan, in what was then the Austrian Empire, to a Serbian Orthodox priest and a mother who was known for her knack for mechanics. Tesla grew up surrounded by an environment that encouraged his fantastic memory and interest in math and science. He attended the Karlovac Gymnasium, then went to Graz University of Technology to study electrical engineering, and later spent some time at Charles University in Prague, although he did not earn a degree from either school.
In the early 1880s, Tesla worked in telephony and for Continental Edison in Paris, where he gained practical experience with electrical power systems. He moved to the United States in 1884 and briefly worked at the Edison Machine Works in New York City. However, his partnership with Thomas Edison ended quickly due to disagreements over payment and technical ideas. Tesla soon started his own venture and, with help from investors, set up labs in New York. There, he developed his important AC induction motor and polyphase alternating current patents. Westinghouse Electric licensed these patents in 1888, which became the basis for the AC power distribution systems that power homes and industries around the world today.
In the 1890s, Tesla carried out high-voltage, high-frequency experiments in New York and in a special lab at Colorado Springs, looking into wireless power transmission and lighting. He created one of the first remote-controlled vehicles, a boat guided by radio, and showed it to the public in 1898. His dramatic presentations made him a popular public figure, and he entertained scientists, business people, and socialites with impressive electrical demonstrations in his lab. One of his most ambitious projects was the Wardenclyffe Tower on Long Island, designed to be a global wireless communication and power transmission center. However, he ran out of funds, and the unfinished tower was pulled down in 1917.
Even though the Wardenclyffe project collapsed, Tesla kept inventing into the early 1900s, securing patents for turbines, oscillators, and other devices. He received the Edison Medal from the American Institute of Electrical Engineers in 1916 and the Elliott Cresson Medal in 1894, along with many other tributes. He was honored as a Fellow of the IEEE and the American Association for the Advancement of Science, and received honorary awards, including a doctorate from the University of Zagreb and the Knight Grand Cross of the Order of Saint Sava, as well as the Grand Cross of the Order of the White Lion in 1936. Tesla lived out his later years in relative poverty and seclusion at the Hotel New Yorker, where he passed away on 7 January 1943. In recognition of his contributions, he was inducted into the National Inventors Hall of Fame posthumously in 1975, and the SI unit of magnetic flux density was named the tesla in 1960 to honor him.
Before Fame
Tesla was born on July 10, 1856, in Smiljan, a village in what was then the Austrian Empire, in a Serbian family. His father, Milutin Tesla, was an Orthodox priest, and his mother, Georgina Đuka Tesla, had no formal education but was credited by Tesla as the source of his inventive spirit. From a young age, he had an exceptional memory and could do integral calculus in his head, which led his teachers to suspect he was cheating. He went to Karlovac Gymnasium and later enrolled in Graz University of Technology in 1875. There he studied electrical engineering and became interested in alternating current motors after seeing a direct current Gramme machine.
After leaving Graz without a degree and recovering from a personal crisis, Tesla attended Charles University in Prague. He eventually moved to Budapest in 1881 to work for the American Telephone Company. During a walk in a city park there, he reportedly came up with the rotating magnetic field principle, which became the basis for his AC induction motor. He then moved to Paris to work for Continental Edison, where he got hands-on experience with large electrical installations. A recommendation later brought him to New York City in 1884 with only a letter of introduction to Thomas Edison and four cents in his pocket.
Key Achievements
- Developed the polyphase alternating current induction motor and transformer, whose patents were licensed by Westinghouse Electric and became the basis of modern AC power distribution
- Conducted foundational experiments in high-frequency electricity that contributed to the development of radio technology
- Built and demonstrated one of the world's first radio-controlled vehicles, a wirelessly guided boat, in 1898
- Designed the AC generators and transmission system used at Niagara Falls, the first large-scale hydroelectric power station in North America
- Received the Edison Medal (1916), Elliott Cresson Medal (1894), and John Scott Award (1934), and was posthumously inducted into the National Inventors Hall of Fame in 1975
Did You Know?
- 01.Tesla claimed to have conceived the rotating magnetic field principle during a walk in a Budapest park in 1882 while reciting a passage from Goethe's Faust.
- 02.His 1898 radio-controlled boat, demonstrated at Madison Square Garden, was so technically advanced that some audience members believed it was guided by a trained monkey hidden inside.
- 03.Tesla reportedly had an extreme aversion to pearls and refused to speak to any woman wearing them, once sending his secretary home to change her jewelry.
- 04.At his Colorado Springs laboratory in 1899, Tesla generated artificial lightning bolts measuring up to 135 feet in length, producing thunder heard 15 miles away.
- 05.Tesla held approximately 300 patents across 26 countries by the time of his death, covering inventions ranging from AC motors to a bladeless turbine.
