Quick Facts
Tesla worked for Thomas Edison, then quit after a dispute over money.
His AC system won the 'War of the Currents' because it could transmit power over long distances.
He built a 187-foot tower on Long Island to test wireless power. It was never completed.
He claimed to have invented a 'death ray' that could bring down airplanes.
He died alone in a hotel room, owing thousands of dollars in rent.
Visual answer
Tesla's Greatest Inventions
The ideas that made Tesla famous, then forgotten, then famous again.
Alternating Current (AC)
The system that powers the world. AC can travel hundreds of miles. DC, Edison's system, could only go about a mile.
Tesla Coil
A high-voltage transformer that produces spectacular lightning-like discharges. Still used in radios and televisions.
Radio
Tesla demonstrated radio in 1893, before Marconi. The Supreme Court later credited Tesla with the invention.
Wireless Power
Tesla dreamed of transmitting electricity through the air. He built a tower to test it. It failed, but the dream lives on.

The Story
How a Quitting Job Changed the World
When Nikola Tesla arrived in the United States, he had four cents in his pocket and a letter of introduction to Thomas Edison. Edison, already famous for the light bulb, hired the young immigrant immediately.
The two men were a perfect mismatch. Edison was a tinkerer who solved problems by trial and error. Tesla was a theorist who designed machines in his head and then built them perfectly on the first try. Edison promised Tesla a large bonus if he could fix a problem with Edison's direct current generators. Tesla did it. Edison said the bonus was a 'joke.' Tesla quit on the spot.
The feud that followed, the War of the Currents, was brutal. Edison publicly electrocuted animals to prove that Tesla's AC system was dangerous. Tesla staged spectacular lightning shows to prove it was safe. In the end, AC won because it could transmit power over long distances. Every time you plug in a phone charger, you are using Tesla's system.
Famous Quote
"I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the mind unfolding to success."
, Nikola Tesla
Tesla felt this thrill many times. He also felt the opposite: the despair of seeing his ideas fail or be stolen.

Analogy
Tesla Was Like a Rock Star Who Died Broke
The familiar part
Imagine a musician who sells out stadiums, then ends up forgotten, then becomes famous again decades after death, and then has a car company named after him.
How it applies
That was Tesla. In the 1890s, he was a celebrity. He gave public lectures with lightning bolts shooting from his hands. He was friends with Mark Twain. Then his ideas got too weird. He claimed to have invented a death ray. He fell in love with a pigeon. People stopped taking him seriously.
Where the analogy breaks
Rock stars usually have groupies. Tesla had pigeons.
Curiosity Notes
Details Most People Miss
Why this still matters
Why This Still Matters
Tesla's story is still told because it is the ultimate tale of the misunderstood genius. He was right about AC. He was right about radio. He was probably wrong about the death ray and wireless power. But the mix of brilliance and eccentricity makes him irresistible. He is the patron saint of inventors who are ahead of their time, which is to say, inventors who will die poor and unappreciated. The car company named after him is a monument to that irony.

Final insight
A Last Thought
Nikola Tesla gave us the gift of electricity delivered to our homes. We owe him the lights that turn on, the phones that charge, and the screens that glow. He died broke in a hotel room, cared for only by a hotel manager and a collection of pigeons. There is no justice in that. But there is a lesson: the world does not always reward its greatest benefactors. Sometimes it forgets them. And sometimes, a century later, it remembers.
Quick answers
Common questions
Did Tesla invent the death ray? +
He claimed to have invented a 'teleforce' weapon that could bring down airplanes from 250 miles away. He tried to sell it to various governments. No one bought it. Most historians believe it was either a hoax or a delusion.
Was Tesla a genius or a madman? +
Both. He was undoubtedly a brilliant inventor. He also had obsessive-compulsive tendencies, a phobia of germs, and a romantic attachment to a pigeon. Genius and madness are not opposites. They are neighbors.
