Nikola Tesla

← Encyclopedia

Nikola Tesla (1856–1943) was the Serbian-American inventor whose polyphase alternating-current system and induction motor set the pattern on which electric power is generated and distributed to this day, and whose high-frequency resonant transformer — the Tesla coil — opened the territory from which radio engineering grew. That much is patent record, court record, and working infrastructure. Around it stands a second, posthumous figure: the suppressed genius of free energy, the man who heard the planets. The last four decades of his life went to projects of planetary scale, described with total conviction and never completed, and the distance between what he demonstrated and what he announced is the space the myth has filled.

From Smiljan to the City Park

He was born on 10 July 1856 in Smiljan, a village on the Military Frontier of the Austrian Empire in present-day Croatia, a son of a Serbian Orthodox priest. At the Polytechnic School in Graz, from 1875, the school’s new Gramme dynamo sparked badly at the commutator brushes, and Tesla suggested the commutator might be dispensed with altogether; his physics professor devoted a lecture to explaining that this amounted to perpetual motion. In 1880 he went to Prague, at his father’s wish, still without a working answer.

The answer came in Budapest, where he had gone to work on the newly arriving telephone system and where a nervous collapse of strange intensity — he reported hearing the ticking of a watch three rooms away — preceded the most famous scene in his own telling of his life. Walking in the City Park at sunset in early 1882, reciting Goethe’s Faust from memory, he saw the rotating magnetic field complete in his mind, drew diagrams in the sand with a stick, and told his companion, “See my motor here; watch me reverse it.” The scene comes to us only from Tesla, in the autobiography he serialized in 1919, told with a visionary’s certainty that the machine existed whole before any iron was cut.

Edison, Westinghouse, and the currents

Paris and the Continental Edison Company followed, then, in 1884, New York and the Edison Machine Works. His own account of that year is admiring of Edison and bitter about the ending: he redesigned two dozen of the company’s machines, was promised fifty thousand dollars, and resigned when the promise was treated as a joke. In April 1887 the new Tesla Electric Company gave him a laboratory, and the motors he built there ran, he said, exactly as he had pictured them in Budapest. In May 1888 he presented the polyphase system in an address to the American Institute of Electrical Engineers, and that year George Westinghouse arranged to manufacture the motors under license to his patents.

The rivalry the newspapers called the war of the currents was, on its technical side, an argument about transmission: direct current served its own neighborhood; alternating current could be stepped up and carried far. The campaign against AC — staged electrocutions, the promotion of the electric chair — issued from the Edison side; economics decided the outcome. Westinghouse lit the Chicago world’s fair of 1893 on the Tesla system, and when the Niagara Falls generating station, built under his patents, sent power to Buffalo in November 1896, the argument was over. Tesla, an American citizen from 1891, kept the citizenship papers in a safe, his medals packed in old trunks.

High frequency, London, and the séance question

In November 1890 he lit sealed, electrodeless glass tubes across open space, and from that work came the air-cored resonant transformer patented in 1891 — the Tesla coil, to this day the standard producer of high-voltage, high-frequency discharge. The lectures that followed made him famous, and in February 1892 brought him to London — the Institution of Electrical Engineers, then the Royal Institution — where Lord Rayleigh’s praise, he said, turned him toward one big idea.

London also fixed the friendship most relevant to the esoteric side of his story: William Crookes, whose work on radiant matter, Tesla said, had decided him on an electrical career when he read it as a student. The two discussed spiritualism together, and Tesla was under the sway of that conversation weeks later when his mother lay dying. Exhausted at her bedside, he dreamed of a cloud bearing angelic figures, one of which took on his mother’s face, woke to unearthly singing, and knew with certainty that she had died — which was true. He wrote to Crookes in the grip of the experience. The sequel, though, is pure Tesla: after months of searching he traced the angelic cloud to a painting he had seen and the music to the Easter mass of a nearby church, and concluded that psychical phenomena, so far as his experience went, rested on no foundation at all. The man whom occult literature later adopted as a mystic reported exactly one borderline experience and explained it away himself.

Telautomatics and the 1943 radio decision

His Fifth Avenue laboratory burned in 1895. In 1898 he exhibited a boat steered and signaled entirely by wireless control; the basic patent issued that November — only, he recalled, after the Patent Office’s Examiner-in-Chief came to New York in person, the claims seeming unbelievable. Tesla named the art telautomatics and forecast machines acting as if possessed of judgment — adding that he himself was such an automaton.

On radio priority the documents are exact. Tesla’s patent No. 645,576, applied for on 2 September 1897 and allowed on 20 March 1900, disclosed a four-circuit system, two circuits each at transmitter and receiver, all tuned to the same frequency. In June 1943, five months after his death, the Supreme Court decided Marconi Wireless Telegraph Co. of America v. United States (https://www.law.cornell.edu/supremecourt/text/320/1). The decision is often summarized as the Court naming Tesla the inventor of radio; its actual holding was narrower. The broad claims of Marconi’s four-circuit tuning patent of 1904 were ruled invalid as anticipated by prior art — above all by John Stone Stone, with Tesla and Oliver Lodge also ahead of Marconi — and one remaining claim was sent back to the Court of Claims. The Court stated plainly that “Marconi’s reputation as the man who first achieved successful radio transmission rests on his original patent, which became reissue No. 11,913, and which is not here in question.” Tesla’s anticipation of the tuned four-circuit apparatus is law; sole invention of radio is not what the case held.

Colorado Springs

In the spring of 1899 he moved to a station outside Colorado Springs and built the device he called the magnifying transmitter — a giant resonant transformer he considered his most important invention, made not merely for sparks but to excite the earth itself. His conviction, never withdrawn, was that the planet is a conductor that can be set into electrical resonance, so that power impressed on it at one point could be drawn from it at any other — energy everywhere for the taking, by anyone with a tuned receiver. He produced discharges he reported at a hundred feet and concluded that he had established stationary waves in the earth, a claim never substantiated in the form he meant it.

One night in 1899 his instruments registered faint, regularly spaced disturbances he could not assign to any cause known to him. He announced them in Collier’s Weekly in February 1901 as possibly the first signals received from another world — “The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another” (https://earlyradiohistory.us/1901talk.htm) — adding that with two thousand horsepower he could signal Mars with certainty. Later writers have proposed natural origins, terrestrial and astronomical, for what his receivers caught; the episode stands at the head of the lineage of listening that runs to SETI.

Wardenclyffe

He returned to New York in 1900 and won J. Pierpont Morgan’s backing for a transatlantic wireless station — by the standard accounts, $150,000. On Long Island at Shoreham he built a brick laboratory and raised a tower 187 feet high, designed for a spherical terminal about 68 feet across. Morgan had funded message traffic; Tesla quietly enlarged the plan toward his World-System — telephony, broadcasting, navigation signals, and above all power without wires, the Colorado conviction built in steel. Marconi bridged the Atlantic in December 1901 with apparatus costing a fraction of Wardenclyffe’s; Morgan declined to invest further; the plant never went into service, and by 1906 the work had effectively stopped. Mortgaged against Tesla’s debts to the Waldorf-Astoria, the property passed out of his hands, and on 4 July 1917 a salvage firm began dynamiting the tower for scrap; it was fully down by September. In 1919 Tesla rejected the wartime rumor of government demolition, defended Morgan as having kept his promise to the letter, and declared the project delayed only by the laws of nature and a world not yet ready — a triumph deferred, in his accounting, not refuted.

The birthday table

From his seventy-fifth birthday in 1931, when Time put him on its cover, Tesla gave annual birthday audiences to the press, and those interviews are the documentary substance of the late projects. In 1934 he described a defensive weapon the papers christened a death ray and he insisted was no ray at all: concentrated streams of minute particles projected through the open air by electrostatic force, with claimed ranges of hundreds of miles — a weapon, he said, that would make every border impassable and war pointless. What survives on paper is a technical memorandum of 1937, The New Art of Projecting Concentrated Non-dispersive Energy through Natural Media, which he circulated to several governments; Marc Seifer traced a Soviet test arrangement through the Amtorg agency, with a $25,000 payment, and a copy of the paper is preserved in the Belgrade museum archive. Nothing was built. In the same years he told reporters he had measured cosmic-ray particles moving faster than light, rejected relativity and curved spacetime outright — empty space, he held, has no properties to curve — and returned to his old idea that thought forms images that might one day be read and projected. None of it came with apparatus or data; it was said at a birthday table, and printed because the name was Tesla.

The private figure of those years is documented chiefly through John O’Neill, the science editor who knew him: the fastidious solitude, the unpaid hotel bills, the modest consulting stipend Westinghouse arranged, and the pigeons he fed daily and nursed when injured — above all a white bird he told O’Neill he had loved as one loves a person, whose death he took as a sign his own work was finished.

January 1943 and the seized papers

He died alone in his room at the Hotel New Yorker on 7 January 1943, aged eighty-six. His nephew Sava Kosanović, a Yugoslav official, reached the room the next morning and believed papers and a notebook were already missing. Two days after the death the Office of Alien Property took custody of his entire effects — though Tesla had been a United States citizen for more than fifty years — and the FBI’s released file on the affair is public in three parts at the Bureau’s records vault (https://vault.fbi.gov/nikola-tesla). The released record shows wartime anxiety rather than buried treasure: the New York field office calling the preservation of the papers a vital government interest, and the MIT engineer John G. Trump spending three days with the trunks and reporting that Tesla’s efforts of the previous fifteen years had been “primarily of a speculative, philosophical, and somewhat promotional character,” without new workable principles. PBS’s account of the missing papers (https://www.pbs.org/tesla/ll/ll_mispapers.html) traces the aftermath: copies of the particle-beam material examined in a postwar Air Force project that closed without published result, the copies unaccounted for afterward. The file documents custody, dispersal, and an unimpressed expert; it does not document a recovered weapon. In 1952 the estate was released to Kosanović and shipped to Belgrade, where the Nikola Tesla Museum, opened that year, holds the archive — some 160,000 documents, inscribed in UNESCO’s Memory of the World register in 2003 — together with his ashes in a gilded sphere.

The myth and the man

The posthumous Tesla grew quickly. By 1959 Margaret Storm’s contactee text Return of the Dove presented him as an emissary from Venus, and he has held a place in the genealogies of UFO religion ever since. The free-energy movement made Wardenclyffe its central relic: the tower reread as a working gift of limitless power, Morgan’s withdrawal as suppression by finance — a story the documents do not bear, since what Morgan stopped funding was a transmitter that had yet to carry a message, and what Tesla had demonstrated was resonance and spark, never delivered power at distance. His name now travels with zero-point devices dressed in the vocabulary of quantum physics, with the Philadelphia Experiment legend of a teleported warship, and with a saying about the numbers three, six, and nine that circulates over his signature without a documented source. The reception has an identifiable engine: Tesla really did speak in the idiom the myth requires — the resonant earth, energy free to all, beams to end war — and with the authority of unquestioned achievement, the very authority the myth borrows. What the myth discards is his habit of explanation: the man who traced his one visionary experience to a painting and a church choir would have made a poor disciple of his posthumous self. In 1960 the General Conference on Weights and Measures gave his name to the SI unit of magnetic flux density; of his two monuments, the tesla and the myth, that is the one with his engineering in it.

The biographers and the archive

The first biography, John J. O’Neill’s Prodigal Genius: The Life of Nikola Tesla (1944), by the journalist who had known him for decades, preserved anecdotes found nowhere else and set the prophetic tone that later popular writing inherited. Marc Seifer’s Wizard: The Life and Times of Nikola Tesla (1996) recovered the documentary trail of the late projects, including the fate of the 1937 paper. The standard scholarly life is W. Bernard Carlson’s Tesla: Inventor of the Electrical Age (Princeton University Press, 2013), which treats the inventions as disciplined workings-out of governing ideals and the showmanship as part of the method (https://press.princeton.edu/books/paperback/9780691165615/tesla). Tesla’s own telling is fully accessible: the 1919 autobiography My Inventions is online in full (http://www.tfcbooks.com/e-books/my_inventions.pdf), and the Collier’s Weekly article on the planetary signals, the 1943 decision, and the FBI file are linked above. The physical archive is at the Nikola Tesla Museum in Belgrade; the surviving Wardenclyffe laboratory at Shoreham is held by the Tesla Science Center founded to preserve it.
