Early Life and Education
Born on July 10, 1856, in Smiljan, Austrian Empire (modern-day Croatia), Nikola Tesla was the fourth of five children in a Serbian family. His early fascination with engineering clashed with his father’s wish for him to join the clergy. Despite financial hardships forcing him to leave Graz University of Technology without a degree, Tesla’s self-driven studies in physics and mathematics laid the foundation for his groundbreaking work.
Key Milestones:
- 1875–1880: Studied in Graz and Prague, focusing on electrical engineering.
- 1882: Conceptualized the rotating magnetic field while working for Edison’s Paris subsidiary.
- 1884: Emigrated to the U.S., joining Edison’s lab before parting ways over a payment dispute.
The AC Revolution and "Current War"
Tesla’s invention of the alternating current (AC) induction motor in 1887 revolutionized power transmission. Partnering with George Westinghouse, he championed AC over Edison’s DC system, culminating in the electrification of the 1893 Chicago World’s Fair. This victory marked the dawn of modern electrical grids.

Notable Achievements:
- 1888: Patented the Tesla coil, enabling wireless energy transfer.
- 1891: Became a U.S. citizen and developed high-frequency AC generators.
- 1895: Designed Niagara Falls’ first hydroelectric plant, powering Buffalo, NY.
Wireless Energy and Futuristic Visions
Tesla’s later work focused on wireless communication and energy transmission. His Wardenclyffe Tower (1901–1905) aimed to provide free global wireless power but was halted due to funding issues.
Pioneering Inventions:
- X-Ray Research: Preceded Röntgen’s discoveries but lost notes in a lab fire.
- Radio Technology: Developed early radio transmitters, though Marconi initially received credit.
- "Death Ray": A particle-beam weapon concept (1930s) later explored in defense tech.
Legacy and Later Years
Tesla’s final decades were marked by financial struggles and eccentric behavior, yet his genius endured. He died alone on January 7, 1943, in New York City.
Honors:
- SI Unit: The tesla (T) measures magnetic flux density.
- Belgrade Museum: Houses his ashes and 160,000 documents, recognized as a UNESCO Memory of the World.
- Pop Culture: Featured in films, comics, and as the namesake of Tesla, Inc. (electric cars).
FAQ
Q: Why did Tesla abandon AC patents?
A: To ensure free access to electricity, Tesla forfeited royalties, prioritizing humanity over profit.
Q: Was Tesla involved in the "Philadelphia Experiment"?
A: No evidence links him to this myth; it conflates his work with later military projects.
Q: How did Tesla envision the future?
A: He predicted wireless communication, renewable energy, and AI-driven automation.
