Twain and Tesla photograph
By Ken Zurski
Around the same time Nikola Tesla was making waves in America for inventing an alternating current (AC) electrical power source and engaging in a “War of Currents” with his former employer and now adversary Thomas Edison, one of the Serbian-born scientist and engineer’s lesser known laboratory experiments took an unexpected and unusual turn.
It was in the 1890’s and Tesla had perfected what he called the Oscillator, or an AC generator that introduced a reciprocating piston rather than the standard rotating coils to generate power. Tesla used steam to drive the piston back and forth and a shaft connected to the piston moved the coils through the magnetic field. The result was higher frequencies and more current than conventional generators.
He patented this machine and unveiled it to great curiosity at the Chicago World’s Fair. “Mr. Tesla has taken what may be called the core of a steam engine and the core of an electrical dynamo, given them a harmonious mechanical adjustment, and has produced a machine which has in it the potentiality of reducing to the rank of old metal half the machinery at present moving on the face of the globe,” the New York Times raved.
Proving the “mad scientist” was never satisfied with his own work and always tried to improve what he had already achieved, when Tesla returned to his New York lab he attempted to use compressed air instead of steam. He built this on a platform that vibrated at a high rate, driving the piston when the column of air was compressed and then released. Even though it didn’t generate enough electricity to power a lighting system, Telsa was amused nonetheless, especially when he stood on the platform. “The sensation experienced was as strange as agreeable,” he wrote, “and I asked my assistants to try. They did so and were mystified and pleased like myself.”
Only one problem. Each time Tesla or one of his assistants stepped off the platform, they had to run to the toilet room. The reason was obvious, especially to Tesla. “A stupendous truth dawned upon me. Some of us, who had stayed longer on the platform, felt an unspeakable and pressing becessity which had promptly been satisfied.”
Basically, they had a sudden urge to empty their bowels.
Intrigued, Tesla kept experimenting and ordering his assistants to “eat meals quickly” and “rush back to the lab.” Tesla may have failed in an attempt to upgrade his own machine, he thought, but succeeded in the prospect at least of using electricity to cure a number of digestive issues.
But to be sure, he unsuspectingly enlisted the help of a friend.
Mark Twain and Tesla were seemingly unlikely acquaintances. In addition to his writing, Twain was a failed inventor, or at least a failed backer of inventions, like the automatic typesetting machine which he poured thousands of dollars into and even more into finding a workable electric motor to power it. Unsuccessful, Twain read about Tesla’s AC steam-powered motor generator and gushed at its simplicity and ingenuity. “It is the most valuable patent since the telephone,” Twain wrote without a hint of his usual sarcasm.
Tesla had sold his invention to lamp maker George Westinghouse’s company which also impressed Twain who lost a sizable portion of his own fortune on the typesetter machine. So at some point the two men met and Twain visited Tesla’s lab. The result is a famous photograph of Twain in the foreground acting as a human conductor of electricity as Tesla or an assistant looms mysteriously in the background. But Tesla fondly remembers helping his friend too. “[Twain] came to the lab in the worst shape,” Tesla recalls, “suffering from a variety of depressing and dangerous elements.”
As the story goes, Twain stepped on the vibrating platform as Tesla had suggested. After a few minutes, Tesla begged him to come down. “Not by a jugfull,” insisted Twain, apparently enjoying himself. When Tesla finally turned the machine off, Twain lurched forward looked at Tesla and pleadingly yelled: “Where is it?”
He was, of course, asking for direction to the toilet room. “Right over there,” Tesla responded chuckling. But Tesla knew he had done Twain a favor. “In less than two months, he regained his old vigor and ability of enjoying life to the fullest extent.”
Of course, Tesla never did patent or market a machine for such a specific purpose and Twain didn’t talk about it, so it’s mostly lost to time, unlike the photograph. Both men now have an important place in history and numerous books are written about them. Twain’s recollections are mostly in his own hand. But the story of Twain’s visit to Tesla’s lab and Twain’s resulting step on the oscillating platform is found in Tesla’s versions, not Twain’s.
Perhaps, as one Tesla biographer suggests, it was all a big practical joke, which certainly – and quite remarkably – turns the tables on both men’s reputations considering Twain was the humorist and Tesla the brain.
Despite this, and knowing the outcome, even if it was only intended for a laugh, both men were likely pleased with the results.
But for completely different reasons.
