Inventor · 1856 – 1943
Nikola Tesla
Key Takeaways
- Tesla developed the alternating-current (AC) system that powers the modern world.
- He invented the AC induction motor and the Tesla coil.
- He held hundreds of patents and conducted visionary research on wireless power.
- He won the "War of the Currents" against Edison's direct current.
Nikola Tesla was the visionary engineer who helped light up the modern world. A Serbian-American immigrant of extraordinary imagination, he gave us the electrical system on which civilization now runs.
Alternating current
Tesla’s greatest achievement was the alternating-current (AC) system, which — unlike the direct current promoted by his rival Thomas Edison — could carry electricity efficiently over long distances. In the “War of the Currents,” AC prevailed, and it remains the basis of the world’s power grids, including the harnessing of Niagara Falls.
Inventor and visionary
Tesla invented the AC induction motor, the Tesla coil, and held hundreds of patents. He pursued bold ideas far ahead of his time, including the wireless transmission of power and information — anticipating technologies that would only later become reality. Building on the electrical pioneering of Benjamin Franklin, he helped open the modern electrical age alongside physicists like Einstein.
Legacy
Brilliant but unworldly, Tesla died alone and in debt despite the immense value of his work. Long overshadowed, he is now celebrated as one of history’s great inventors — a kindred spirit to Leonardo da Vinci — with the unit of magnetic flux density, and a famous car company, bearing his name.
Influence
Tesla's alternating-current system became the foundation of global electrical power, and his inventions and ideas underpin much of modern electrical and wireless technology.
Legacy
Once overshadowed, Tesla is now celebrated as a visionary genius of the electrical age; the unit of magnetic flux density and a famous car company bear his name.
Controversies
- His visionary later projects, such as wireless global power, were never realized and left him impoverished.

Frequently Asked Questions
Who was Nikola Tesla?
Nikola Tesla (1856–1943) was a Serbian-American inventor and electrical engineer whose alternating-current system and many inventions helped electrify the modern world.
What was the War of the Currents?
It was the competition between Tesla's alternating current (AC) and Edison's direct current (DC) for the standard of electrical power; AC ultimately prevailed for long-distance transmission.
