Nikola Tesla
Serbian‑American inventor and electrical engineer (1856–1943) whose work on alternating current, the induction motor and the Tesla coil helped shape modern electrical power and early wireless technology.
Photo by Brecht Corbeel on UnsplashNikola Tesla (1856–1943) was a Serbian‑American inventor and electrical engineer noted for the development of polyphase alternating‑current systems and the induction motor.
He invented the Tesla coil and performed high‑voltage, high‑frequency experiments that influenced early radio and lighting technologies; his life combined influential technical achievements with later financial and personal struggles.
Quick facts
- Nikola Tesla was born July 10, 1856 in Smiljan (then in the Austrian Empire, now in Croatia) and died January 7, 1943 in New York City. ([englishdocs.eu](https://englishdocs.eu/nikola-tesla/?utm_source=openai))
- He was a Serbian‑American inventor and electrical engineer who developed and patented the rotating magnetic field and the polyphase alternating‑current system that underpins modern AC power generation and motors. ([englishdocs.eu](https://englishdocs.eu/nikola-tesla/?utm_source=openai))
- In 1891 Tesla invented and publicly demonstrated the resonant high‑frequency transformer that became known as the Tesla coil; his high‑frequency work influenced early radio and related technologies. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Tesla_coil?utm_source=openai))
- Tesla sold key patents and worked with George Westinghouse on AC power distribution (helping win the so‑called 'War of the Currents'); he later relinquished royalty claims that would have made him enormously wealthy.

- Many later claims about Tesla (for example, that he single‑handedly invented commercial radio or had a working 'free energy' system) are exaggerated or incorrect; the U.S. Supreme Court acknowledged Tesla's prior patents in a 1943 decision related to Marconi litigation, but history of radio is complex and not a single‑inventor story.

A surprising fact
The SI unit of magnetic flux density is named the tesla (T) in his honour — the name was adopted by the international community (General Conference on Weights and Measures) in 1960. ([technav.ieee.org](https://technav.ieee.org/topic/magnetic-flux-density/?utm_source=openai))
