Wizard: The Life and Times of Nikola Tesla (22 page)

Since the contracts with Westinghouse and GE had been signed, Adams no longer had to pretend to be unbiased; now he was free to seek business ventures. He came down to New York to visit Tesla at his laboratory, and there Adams was introduced to the inventor’s new mechanical and electrical oscillators and to a revolutionary new AC system of lighting that was vastly superior to the existing one. Adams offered Tesla $100,000 for a controlling interest in “fourteen U.S. patents, many foreign patents,” and any future inventions which Tesla might conceive. The inventor accepted the proposal.
²⁵
In February 1895, the creation of the Nikola Tesla Company was formally announced, with the directors being Tesla, Alfred S. Brown of New York, Charles Coaney of New Jersey, William B. Rankine of Buffalo, Edward D. Adams, and Adams’s son Ernest of Boston.

Tesla had reached the inner sanctum of the corporate world. He now had on his board two of the most important members of the Niagara project, and he was sitting on at least a half-dozen entirely new inventions, each of which had the potential for creating completely new industries. His mechanical oscillators looked as if they were going to replace the steam engine; his electrical oscillators were intrinsic to his system of fluorescent lighting, remote control, and his now secret work in wireless transmission; and there were other ideas as well, such as his work in artificial intelligence, ozone production, “cheap refrigeration, and cheap manufacture of liquid air, the manufacture of fertilizers and nitric acid from the air.”
²⁷
However, all of these inventions were still, to a great extent, in their developmental stages, and Tesla’s strong suit was never in manufacturing. He gained his backers ostensibly because of his track record in AC and because of the promise held by his cold light and various oscillators. But his real interest, his passion, remained in the wireless transmission of power, and most of his time was spent in that direction.

Dear Mr. Tesla,

Early in 1894, I told our mutual friend…T. C. Martin, that your book “The Inventions, Researches and Writings of Nikola Tesla,” would still be considered a classic a hundred years hence. I have not changed my opinion…The application of the principles therein first enunciated have definitely changed for the better, life on this planet.

n February 1894, Tesla went with T. C. Martin to the laboratory of Mr. Bettini, an inventor who had advanced Edison’s work in the perfection of the phonograph. “He wants to display his marvelous collection of song cylinders—Madam Melba, deReszke, Salvini and Bernhardt,” Martin wrote. “He wishes the honor of catching your voice as well.”
²

During this time, Martin continued to forward reviews from
Book News, Physics Review,
and
London Electrician.
“Praise from Sir Herbert [Spencer] is praise indeed,” the editor wrote. “Thanks for continuing the Russian translation; the German edition is selling as well.”
³

On the home front, Tesla had formed a new company with two of the coordinators of the Niagara project, and he was now turning his attention to designing a wireless system that would be able to transmit light, information, and electrical power. Thus, the inventor worked to perfect his mechanical and electrical oscillators and vacuum lamps. The mechanical oscillator could efficiently convert steam to electrical power, the electrical oscillator could produce the frequencies necessary for power transmission, and the wireless fluorescent bulbs could be illuminated when the correct wavelengths were reached capable of engendering light. According to Tesla’s theory, if the ether could be made to oscillate at 500 trillion times per second, pure light would be created. Below that figure, heat was produced.
⁴

T. C. Martin continued to play a role somewhat like a manager. In the spring he set up a sitting for the inventor before the sculptor Mr. Wolff, and to Tesla’s dismay, he also arranged an interview with S. S. McClure, the well-known magazine editor. Tesla had too many events crammed into his calendar, but T. C. persisted.

“I cannot very well call off McClure now,” Martin wrote, “after your little dinner which has simply made him more eager than ever for the article.” Ending the missive with customary praise, Martin wrote, “He knows now personally, what he knew before only by hearsay, viz that you are a great man and a nice fellow. I excuse your blushes.”
⁵

It would take nearly a year for the
Century
to complete its own article and organize the photographing of the celebrated individuals who came to 33-35 South Fifth Avenue, but finally, in April 1895, Martin’s follow-up piece appeared. Even today, a century later, it remains a spectacular testament to the wizard’s fabled laboratory, for not only did it display many fascinating inventions and prognostications; it also presented dazzling multiple-exposure photographs of such stars of the day as actor Joseph Jefferson, poet F. Marion Crawford, and sorcerer Nikola Tesla. “Martin’s article should be read very carefully to be appreciated,” Tesla wrote Johnson.

With thirty-five homes illuminated by gas for every one lit by electricity, the market was ripe for a more efficient source. However, Tesla’s fluorescent lamps were still in an experimental stage, as evidenced by the ten-minute time-lapse photograph of Mark Twain taken for the Martin article.
⁷
The story for Tesla’s steam dynamo was analogous. According to Martin’s figures, nine-tenths of all dynamos in the country were steam driven. The rest gained their power from either compressed air, waterwheels, or gasoline. Since the Tesla oscillator was forty times more efficient than the prevailing steam-driven dynamo, it seemed that the marketing of this product would be highly profitable. But again, the perfection of the device was not completed and therefore not yet marketable. Nevertheless, it was revolutionary, and Tesla contacted Babcock & Wilcox to begin manufacturing prototypes.

Before a large number of physicians and engineers of the American Electro-Therapeutic Association at his laboratory in October 1894, Tesla used the oscillator to generate electricity for over fifty incandescent lamps and vacuum tubes. Also, “arc lights were shown in operation.” Naturally, the oscillator also generated the extremely high frequencies necessary for engendering beneficial electrotherapeutic effects.
⁸

Refining his theory on wireless communication, the inventor realized that electrical energy could be transmitted in two distinctly different ways, one as radiation through the air, and the other as conduction through the ground. Today this difference corresponds to FM and AM radio. (As an
experiment to verify that FM travels mostly through the air and AM mostly through, or along, the ground, drive your car into an underpass and turn on the radio. When you switch on AM [amplitude modulation], you will probably hear static, whereas FM [frequency modulation] comes in loud and clear.) “When I showed my experiments to an audience,” Tesla said, “it would happen that when I wanted to operate single circuits with some devices more than one circuit would respond, and people would call my attention to this…I would then have to say that the circuits were not carefully tuned.”
⁹
Thus the inventor turned his attention to the problem of creating separate channels.

By studying Herbert Spencer’s theories on resultant forces and nerve conduction,
¹⁰
Tesla began to realize that he could design vacuum tubes which would respond only when a precise combination of two or more circuits were being triggered. One of the lamps held by Twain was illuminated in this manner, its dual circuit triggered by a corresponding dual circuit created by two cables laid around the room. Like the combination of a safety lock, this invention not only explains the mechanism behind tuning into different stations on the radio, it also explains the principle behind telephone and TV scramblers. In this way, Tesla attained “the exclusiveness and non-interferability of impulses.
¹¹

Transmitting messages from an outer circuit to an inner circuit twenty feet away was one thing; sending information over long distances was another matter entirely. Tesla had realized for a number of years that the earth carried a charge, and therefore he decided to
utilize the planet
itself as a carrier of electrical energy. If this were so and individualized channels could be created, transmission lines appeared to be superfluous. He therefore began to construct many different-sized coils to connect to the ground (usually via the water-main system) in order to ascertain the terrestrial period of frequency.

With an oscillator constructed for this purpose, Martin wrote, “if he has not yet actually determined the earth’s [precise] electrical charge, or ‘capacity,’ he has obtained striking effects which conclusively demonstrate that he has succeeded in disturbing it…[When his oscillations] are in harmony with the individual vibrations of the [earth], an intense vibration or surging will be obtained.”
¹²
Martin ended the article with the suggestion that with this device not only could information and power be transmitted, but also the weather might be modified. “Perchance, we shall ‘call up’ Mars in this way some day, the electrical charge of both planets being utilized as signals,” Martin concluded, quoting Tesla’s wish at the finale of the exposé.
¹³

Classifying Tesla was becoming more and more difficult. Martin portrayed him in a variety of ways—as a practical inventor, a wizard, and
an iconoclast; critics portrayed him as “an impractical…visionary enthusiast.”
¹⁴
“His inventions already show how brilliantly capable he is,” one newspaper reported, but his “propositions…seem like a madman’s dream of empire.”
¹⁵

“One is naturally disappointed that nothing practical has as yet proceeded from the magnificent experimental investigations with which Tesla has dazzled the world,” Lt. F. Jarvis Patten wrote in
Electrical World.
¹⁶
But his solid accomplishments at Niagara could not be ignored. The article concluded:

Before the general public, he stands as a phenomenal inventor from the Eastern world, from whom is expected little less than if he carried Aladdin’s lamp in his hand, which, of course, is wrong, and an injustice both to the public and to Mr. Tesla…He has doubtless much importance in store for us, but the difference should never be lost sight of between the search for nature’s truths in the lab of the physicist and the reduction of the results attained, however great their promise, to a form suitable for commercial use…If some of the dreams which Tesla and others are cherishing today ever come to realization, the magnitude of the ensuing change in the material life of the world simply defies the imagination.
¹⁷

In Manhattan, Tesla soon caught the eye of Joseph Pulitzer, the German-Hungarian immigrant and owner of the
New York World.
Pulitzer sent his newest reporter, Arthur Brisbane, on the interview. Already one of the most widely read columnists in the nation, Brisbane had recently jumped from Charles Dana’s
New York Sun,
but at age thirty, Brisbane would soon also leave Pulitzer to become head shock reporter for William Randolf Hearst’s up-and-coming yellow
Journal.
He met Tesla in July 1894.

While dining nightly at Delmonico’s restaurant, the reporter was introduced by Mr. Delmonico to “a very handsome young man with a pointed black beard.” Brisbane wrote that “Mr. Delmonico lowers his voice when he speaks of Mr. Tesla, as Boston cab drivers used to lower their voicess in speaking of John L. Sullivan.”

“That Mr. Tesla can do anything,” Delmonico contended. “We managed to make him play pool one night. He had never played, but he had watched us for a little while. He was very indignant when he found that we meant to give him fifteen points. But it didn’t matter much, for he beat us all and got all the money.” Delmonico noted that they were only playing for quarters, but “it wasn’t the money we cared about, but the way he studies out pool in his head, and then beat us, after we had practiced for years. [It] surprised us.”
¹⁸
Considering that Tesla was very proficient at the sport and had slyly kept that information confidential makes the story all the more
interesting. Tesla could be deceptive, particularly in pecuniary matters.

Although the article appeared somewhat disjointed and redundant, it nevertheless aptly described Tesla’s habits and appearance at that time. Tesla would dine frequently at the popular establishment, always choosing a table by the window and usually reading a newspaper. Brisbane described Tesla’s “eyes [as being] set very far back in his head. They are rather light. I asked him how [that] could [be, as he was] a Slav. He told me that his eyes were once much darker, but that using his mind a great deal had made them many shades lighter.” This confirmed a theory on brain usage and eye color that Brisbane had heard about.

Brisbane went on to write that Tesla “stoops—most men do when they have no peacock blood in them. He lives inside of himself.” And yet the article was adorned with the most fantastic full-body engraving of Tesla standing quite unstooped, proud as a peacock, illuminated like a virtual Christmas tree.

This full-page spread remains one of the most spectacular portraits of the inventor ever concocted, and it caused numerous people to ask Tesla how it felt to pump such huge amounts of electricity throughout his body. “I admit that I was somewhat alarmed, when I began these experiments,” Tesla admitted, “but after I understood the principles, I could proceed in an unalarmed manner.”
¹⁹

When pressed for details a number of years later at the Harvard Club, the inventor responded:

[When] the body of a person [is] subjected to the rapidly alternating pressure of an electrical oscillator of two and one half million volts [this] presents a sight marvelous and unforgettable. One sees the experimenter standing on a big sheet of fierce, blinding flame, his whole body enveloped in a mass of phosphorescent streamers, like the tentacles of an octopus. Bundles of light stick out from his spine. As he stretches out the arms, roaring tongues of fire leap from his fingertips as myriads of minute projectiles are shot off from him with such velocities as to pass through the adjoining walls. He is in turn being violently bombarded by the surrounding air and dust.
²⁰

Tesla was walking a difficult line and revealing contradictory natures: reclusive versus natural showman. The interest of the press made it difficult to protect against piracy. He wanted to disclose, for public and historical purposes, his overall goal, but he had to keep vital details confidential. One reporter who had spent a day with “this kindly wizard of Washington Square” revealed that Tesla “confided to me that he was engaged on several secret experiments of most abundant promise, but
their nature cannot be hinted at here. However, I have Mr. Tesla’s permission to say that some day he proposes to transmit vibrations through the earth [so] that it will be possible to send a message from an ocean steamer to a city, however distant, without the use of any wire.”
²¹
Even his laboratory workers were insulated from the details of his secret experiments.
²²

After calculating the size of the planet and the hypothetical wavelength of solar rays, Tesla constructed a transmitter with several circuits capable of engendering their electrical charge into the earth. One end of the instrument was attached to the ground via the radiator or water main, and the other end was connected to a cable which Tesla brought to the roof of the building as an aerial connection. With Mr. Diaz Buitrago, his draughtsman, in charge of the transmitter, the inventor would take his receiving instruments as far as five miles away. His first experiments were set up on the roof of the Hotel Gerlach, approximately thirty blocks from the lab. With balloons filled with hot air, helium, or hydrogen to hold the elevated terminal (aerial) high above the buildings and a cable attached to the water main of the hotel, Tesla set up his receivers and verified that, indeed, electrical energy could be secured from his transmitter.
