The man who electrified the future.

01 A Life in Sparks

From a Croatian parsonage to a Manhattan hotel room, Tesla's 86 years ran on obsession, brilliance, and financial ruin — often at the same time.

1. 1856

   Born in Smiljan

   Born July 10, 1856 in Smiljan, Austrian Empire (now Croatia), the fourth of five children of Serbian Orthodox priest Milutin Tesla and Georgina "Đuka" Mandić, whom Tesla credited with his eidetic memory.

2. 1875

   Graz & Prague

   Enrolled at the Imperial-Royal Technical College in Graz on a military scholarship; left in 1878 without graduating. Later audited philosophy lectures in Prague.

3. 1882

   The rotating field, in a park

   While working for the Continental Edison Company in Paris, Tesla conceived the rotating magnetic field — the principle behind AC motors — reportedly while reciting Goethe's Faust on a walk.

4. 1884

   Arrives in America

   Emigrated to the US and joined Edison Machine Works in Manhattan. After an all-night repair of dynamos aboard the SS Oregon, Edison reportedly called him "a damned good man." He quit six months later in a dispute over an unpaid bonus.

5. 1886

   Bankrupt, digging ditches

   His first company, Tesla Electric Light & Manufacturing, collapsed and investors took his patents. For a time he worked as a laborer for $2 a day.

6. 1887–88

   The AC motor, and Westinghouse

   With new backers he built a lab at 89 Liberty Street and patented a commutator-free AC induction motor (US 381,968). George Westinghouse licensed the polyphase system, igniting the "War of the Currents" against Edison's DC.

7. 1891

   Citizenship & the Tesla coil

   Became a naturalized US citizen at 35 and patented the Tesla coil — a resonant transformer that could generate spectacular high-voltage, high-frequency discharges.

8. 1893

   Chicago lights up

   Westinghouse's "Tesla Polyphase System" illuminated the World's Columbian Exposition, turning public opinion toward AC. Tesla personally demonstrated wireless-lit gas tubes on stage. That year he also advised on the Niagara Falls hydroelectric project.

9. 1895

   The lab burns

   A fire destroyed his South Fifth Avenue laboratory — models, notes, and years of experimental apparatus lost overnight. "I am in too much grief to talk," he told reporters.

10. 1898

    The radio-controlled boat

    Demonstrated a wireless remote-controlled boat — a "telautomaton" — at Madison Square Garden, decades ahead of its time. He tried, unsuccessfully, to sell it to the US military as a guided torpedo.

11. 1899–1900

    Colorado Springs

    Funded by John Jacob Astor IV, Tesla built a high-altitude experimental station and produced artificial lightning up to 135 feet long — and speculated that strange received signals might be interplanetary communication.

12. 1901–17

    Wardenclyffe Tower

    With $150,000 from J.P. Morgan, Tesla began a tower at Shoreham, Long Island, meant to transmit wireless power and messages across the Atlantic. Marconi beat him to a transatlantic radio signal in December 1901; funding dried up by 1904, and the half-finished tower was dynamited for scrap in 1917 to pay Tesla's hotel debts.

13. 1906

    The bladeless turbine

    On his 50th birthday, Tesla unveiled a 200-horsepower bladeless turbine spinning at 16,000 rpm — a radically efficient design using smooth spinning discs instead of blades.

14. 1928

    His last patent: a flying machine

    US 1,655,114, "Apparatus for Aerial Transportation," described a vertical-take-off aircraft with a tilting rotor and wing — a VTOL concept decades before the technology existed to build one.

15. 1937

    "A Machine to End War"

    In Liberty magazine, Tesla described a defensive particle-beam concept the press sensationalized as a "death ray" — he called it Teleforce, and offered it to several governments, none of which built it.

16. 1943

    Death in Room 3327

    Tesla died alone on January 7, 1943 in the New Yorker Hotel, reclusive and largely forgotten by the public, having spent his final years feeding and nursing pigeons from his window. Federal agents seized his papers soon after, citing wartime concerns about his weapons research.

02 Inventions & Ideas

Some changed the world. Some were decades ahead of their time. Some never worked at all — but every one of them was an act of imagination.

AC Induction Motor & Polyphase System

A self-starting motor powered by a rotating magnetic field, needing no commutator. It made alternating current practical to generate, transmit, and use — the foundation of the modern power grid.

1887–88

The Tesla Coil

A resonant air-core transformer producing high-voltage, high-frequency electricity. Built to explore wireless energy transmission, it became — and remains — the icon of "mad science" showmanship.

1891

Wardenclyffe & the World Wireless System

An unfinished tower meant to transmit both electrical power and messages across the globe without wires — Tesla's most ambitious, and most financially ruinous, idea.

1901–17

Wireless Lighting

Long before Wi-Fi, Tesla lit gas-discharge tubes and bulbs from across a stage using high-frequency AC fields alone — proof, he believed, that power itself could one day travel through the air.

1890s

Wireless Power Transmission

Patent 645,576 laid out a scheme to transmit electrical energy without wires — the theoretical seed of Wardenclyffe, and a dream still not fully realized today.

1897–1900

The Tesla Turbine

A bladeless turbine using smooth spinning discs and boundary-layer friction instead of blades — remarkably efficient, mechanically simple, and still studied by engineers today.

1906–11

The Telautomaton

A radio-controlled boat, steered by wireless signal with no human aboard — the ancestor of every drone and remote-controlled vehicle that followed. Tesla envisioned uncrewed weapons and machines "possessed of their own intelligence."

1898

Early X-Ray Experiments

Tesla was independently experimenting with high-energy vacuum tubes and may have captured an accidental X-ray image weeks before Wilhelm Röntgen's official 1895 announcement — but never published or claimed priority.

1894–96

Teleforce ("Death Ray")

A proposed particle-beam weapon that would accelerate tungsten pellets via electrostatic repulsion. Tesla insisted it was a defensive deterrent, not a weapon of aggression, and pitched it to multiple governments — none built it.

1930s–37

Telegeodynamics & the "Earthquake Oscillator"

A small mechanical oscillator Tesla claimed could resonate a building — and, by legend, nearly shook his own Manhattan block apart before he smashed it with a hammer. He proposed scaling the principle to transmit vibrations through the earth itself.

1890s

VTOL Flying Machine

Tesla's final patent, US 1,655,114, described an aircraft that could take off vertically using a tilting rotor and wing — a concept aviation wouldn't catch up to for decades.

1928

03 Selected Patents

Tesla held roughly 300 patents worldwide (about 112 in the US). Patents are public federal records — free to read, and full of his own period prose explaining the reasoning behind each idea.

04 Writings & Quotes

Tesla's own words — from his 1919 autobiography My Inventions, serialized in Electrical Experimenter magazine, to his visionary essays on energy and peace.

"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 brain unfolding to success… Such emotions make a man forget food, sleep, friends, love, everything." — My Inventions, Electrical Experimenter, 1919

"The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter — for the future." — "Radio Power Will Revolutionize the World," Modern Mechanix and Inventions, 1934

"Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I really worked, is mine." — interview, Politika (Belgrade), 1927

"This planet, with all its appalling immensity, is to electric currents virtually no more than a small metal ball." — "The Transmission of Electric Energy Without Wires," 1904

A note on a famous "fake": the widely-shared quote "if you want to find the secrets of the universe, think in terms of energy, frequency and vibration" does not appear in any of Tesla's patents, lectures, or writings — it traces to an unverified secondhand claim from the 1980s and isn't included above.

05 Legacy

Tesla died in debt and relative obscurity. Decades later, his name is everywhere.
