The Book of the Dead (47 page)

Tesla set to the task with his customary application. At first, he was in awe of his new boss. When Edison told him he ate
Welsh rarebit every day to increase his IQ, Tesla took the joke to heart and ate barely anything else for weeks. He found Edison’s sense of humor a lot less amusing when, almost a year later, having solved the problem of the DC generator, Edison refused to pay his bonus: “When you become a full-fledged American you will appreciate an American joke.” He offered him a raise to $25 per week instead. It was a mistake Edison would live to regret. Tesla was incandescent with rage and resigned, spending the next year earning his living as a laborer (ironically at one point digging ditches for Edison’s expanding network of DC cables) and working on his inventions at night.

By early 1887 Tesla had saved enough money to register seven patents covering the full range of AC generators, transformers, transmission lines, motors, and lighting. These were awarded unopposed and would become the most valuable patents registered since the telephone. At a stroke, they solved the thorny problem of long-range power distribution. Direct current required a generator to be located within a mile of where the electricity was being used and was inconveniently inflexible: electricity from the same DC generator couldn’t be used to run machines requiring different voltages. To increase the voltage in a direct current circuit meant also increasing the amperage, which meant thicker copper wire and greater loss of energy through heat. With Tesla’s AC solution, power could be generated at a low voltage, then, using a simple device called a transformer, it could be “stepped up” for transmission and “stepped down” again at the customer’s house or business premises. Taking the analogy of a water pipe—the higher the pressure (voltage), the farther and faster the same amount of water (electrical energy) will travel, but the hose attachments (transformers) will determine
how that water is used at the other end. The elegant simplicity of Tesla’s system attracted the attention of Pittsburgh industrialist George Westinghouse. He hired Tesla, purchased his patents for $60,000, and agreed to pay him royalties of $2.50 for every horsepower of AC electricity sold.

Whether or not Edison saw the writing on the wall, he knew that Tesla and Westinghouse had to be stopped. His war machine rumbled into action. His line of attack was that AC was dangerous. While direct current was “like a river flowing peacefully to the sea,” he alleged, alternating current was “a torrent rushing violently over a precipice.” To make his point in the most brutal way, he began using AC to electrocute animals in public. Twenty-four dogs (bought from local children for 25 cents each), two calves, a horse, and Topsy—a zoo elephant that had killed its keeper—were all “Westinghoused.” Scenting blood, Edison developed the electric chair, secretly acquiring three Tesla generators to make it happen. The first person to die by legal electrocution was messily dispatched using AC at Auburn, New York, in 1890. “They could have done better using an ax,” commented Westinghouse dryly. But Tesla and Westinghouse got their revenge by underbidding Edison for the contract to light the Chicago World’s Fair in 1893, the world’s first major “all-electric” event. Thanks to Tesla’s AC system, Westinghouse could quote a price that was less than half of Edison’s, because so much less copper wire was needed. Edison retaliated by refusing to supply them with Edison lightbulbs, but the game was up. Twenty-seven million people visited the Fair, and from that moment on, 80 percent of all electrical devices bought in the United States were AC. In 1898 the final nail was hammered into DC’s coffin when Westinghouse and Tesla built the world’s first hydroelectric plant, harnessing the power of
Niagara Falls to generate alternating current and piping it the seventeen miles to their new power station in Buffalo, New York.

Tesla had used the money Westinghouse had paid him for his patents to set up a lab on West Houston Street in New York City, and the 1890s were a decade of creative overdrive for him. He discovered X-rays three years before Wilhelm Roentgen and was the first to point out their biological risks. He devised the first radio-wave transmitter two years before Marconi and he invented and patented radio control, demonstrating the first radio-controlled boat in Madison Square Garden in 1898. Having mastered the transmission of AC by wire, by the end of the decade he was sending it through space
without
wires. Showing unexpected talents as a showman, he would enthrall and horrify audiences at public demonstrations by running hundreds of thousands of volts through his own body, lighting electric bulbs from a distance while flames shot from his head and his hands sparked. In 1899 he moved his lab to Colorado Springs to unveil his pièce de résistance. This, he believed, of all of his inventions, would prove the “most important and valuable to future generations.” It was a massive “magnifying transmitter” able to send radio waves and electricity through the air over long distances. At 51 feet in diameter it could generate 4 million volts, and light two hundred lamps, without wires, from twenty-five miles away. Even more astounding, he used it to make artificial lightning, generating electrical flashes more than 130 feet long. In 1900 the banker J. P. Morgan agreed to invest $150,000 in an even bigger wireless transmitter, the Wardenclyffe Tower on Long Island. Tesla’s plan was global: to unite telephone and telegraph systems in a single wireless network, transmitting pictures and text from one side of the globe to the other in minutes, and delivering
mail between special terminals, using electronic messaging. He had, in effect, envisioned the World Wide Web a hundred years early, not only with universal wi-fi, but one where computers could operate without batteries and would never need to be plugged in.

Tesla was forty-four at this point and almost exactly halfway through his life, when, at the peak of his fame and influence, things began to unravel. In 1903 Morgan pulled out of Wardenclyffe, claiming Tesla had sold it to him as a radio transmitter, and betraying a complete lack of understanding of the potential of Tesla’s vision. In 1904 the U.S. Patent Office incorrectly awarded Marconi the patent for radio, even though Marconi’s work had all been achieved after Tesla, actually using Tesla’s own patented instruments. The insult was made worse by the award of the Nobel Prize to Marconi in 1909, just as Roentgen had been awarded his in 1901. Tesla never received one. By 1905 he had run out of funds and was forced to close his lab. Two years later George Westinghouse was almost wiped out by a stock market crash and by the long and expensive turf war with Edison. In desperation, he asked Tesla’s permission to amend their contract. In one of the noblest gestures in modern business, Tesla released Westinghouse completely, saying:

You have been my friend, you believed in me when others had no faith;you were brave enough to go ahead … when others lacked courage; you supported me when even your own engineers lacked vision … you have stood by me as a friend…. Here is your contract, and here is my contract. I will tear both of them to pieces, and you will no longer have any troubles from my royalties. Is that sufficient?

Westinghouse paid Tesla a one-off fee of $216,000. At that time, the value of Tesla’s royalty stood at more than $12 million, enough to make him one of the richest men in the world. If he had kept that royalty until today, even if no more electricity had been generated than the relatively tiny amount that existed in 1890, he would now be worth $40 billion. In 1914, however, the outbreak of World War I cut off the remaining income he had been earning from his European patents, and two years later, he was forced to file for bankruptcy. He never recovered financially, living out the last ten years of his life in room 3327 of the Hotel New Yorker, his bills settled by his friends.

This falling apart of his financial affairs was matched by increasingly unstable personal behavior. His fetish for cleanliness grew to Howard Hughes–like proportions. He went to great lengths to avoid shaking hands, placing his own behind his back when meeting people. At the dining table, he asked that each item of silverware be heat-sterilized before being brought to him. He would then pick up each item with a napkin, clean it with another napkin, and then drop both napkins onto the floor (he got through fifteen napkins a meal on average). If a fly landed on his table, he had to move to another seat and make an entirely fresh start. He gradually abandoned the two-steaks-a-night supper he had once enjoyed, becoming a vegetarian and eating exactly the same food in the same restaurant every night: warm milk, bread, and a concoction made from a dozen vegetables. But he continued to dress nattily. (In 1910 he had announced to a secretary that he was the best-dressed man on Fifth Avenue and intended to maintain that standard.) He wouldn’t go out without his gray suede gloves, which he wore for a week and then discarded. He bought a new red or black tie each week and
would wear only white silk shirts. Collars and handkerchiefs were used only once, and he developed an aversion to jewelry. He could not sit near a woman who was wearing pearls. Most poetic of all, he was sure the hours he’d spent thinking were draining the color from his eyes.

His work became similarly unhinged. He claimed to be getting radio messages from Mars and Venus. He talked about using electricity to control the weather. He proposed a form of eugenics leading to women becoming dominant, so that human society would more closely resemble that of the honeybee. In his late seventies, he announced he was working on a device with which to end all wars, a weapon that

would send concentrated beams of particles through the free air, of such tremendous energy that they will bring down a fleet of 10,000 enemy airplanes at a distance of 200 miles from a defending nation’s border and will cause armies to drop dead in their tracks.

Inevitably, the media dubbed this Tesla’s “death ray,” and it confirmed his passage in the public mind from revered genius to mad scientist.

He died in 1943, aged eighty-six, heavily in debt, alone in his hotel room. In 1944 the U.S. courts finally found in his favor and confirmed that it was Tesla and not Marconi who was the inventor of radio. Much has been done since to restore his reputation, but Edison and Marconi are still the names everyone remembers. Tesla, like Dee and Parsons and even poor Emma Hamilton, was too absorbed in his own passions to be bothered with mere accountancy. He lived with the burden and the joy of having glimpsed a much deeper reality than most people ever
see, and that sense of his special destiny never deserted him. Marriage was not for him, not because he was homosexual or afraid of women, but because nothing could be allowed to interfere with his mission: “I have planned to devote my whole life to my work and for that reason I am denied the love and companionship of a good woman; and more, too.”

Weeks before his death, he had a final feminine visitation. He had befriended a pigeon that came every day to his windowsill in room 3327. She had become his favorite, “a beautiful bird, pure white with light gray tips on its wings.” He had always loved birds, but this one “he loved as a man loves a woman…. She understood me and I understood her.”

Then one night as I was lying in my bed in the dark, solving problems, as usual, she flew in through the open window and stood on my desk. I knew she wanted me; she wanted to tell me something important so I got up and went to her. As I looked at her I knew she wanted to tell me—she was dying. And then, as I got her message, there came a light from her eyes—powerful beams of light. It was a real light, a powerful, dazzling, blinding light, a light more intense than I had ever produced by the most powerful lamps in my laboratory.

When that pigeon died, something went out of my life. Up to that time I knew with a certainty that I would complete my work, no matter how ambitious my program, but when that something went out of my life I knew my life’s work was finished.

Two years after Tesla’s world-changing vision of the revolutionary alternating current motor in a park in Budapest, the
revolutionary political philosopher
Karl Marx
(1818–83) died penniless in London. Marx would have had no truck with Tesla’s mysticism, but history was to unite the life’s work of both men in 1920, when the Marxist regime of the Soviet Union took the momentous decision to transform their vast country by electrification. Lenin believed the success of the revolution was entirely dependent on the rapid rollout of new technology; his favorite slogan was “Communism is socialism plus electrification of the whole country.” In 1948, when George Orwell wanted to personify the evil of the Soviet system in
Animal Farm
, he had the animals build an electrified windmill.

Marx’s journey to penury was less tortured than Tesla’s: As an asylum-seeker and infrequently employed freelance journalist, he never had much money to lose. He wasn’t a “worker” in the way it is usually meant in Marxist mythology. A friend once teased him that she couldn’t imagine his living happily in a communist state as it might mean getting his hands dirty. “Neither can I,” he agreed. “These times will come, but we must be away by then.” Even his adoring mother complained: “I wish you would
make
some capital instead of just writing about it.” Luckily for him, he found a benefactor (and true friend) in Friedrich Engels—fox-hunting mill owner by day, radical socialist by night—who looked after him, as a recent biographer puts it, “like a substitute mother, sending him pocket money, fussing over his health and reminding him to study.” Marx may not have been a manganese miner or a tractor driver, but he certainly worked hard: His collected writings come to more than a hundred volumes and would spawn a political ideology that, at its height, controlled half the world’s population.
