The Time Nikola Tesla Paid for His Hotel Room With a 'Death Ray'

Nikola Tesla was, of course, a vastly accomplished scientist and inventor. His inventions include the Tesla coil and electric oscillators, and he also developed technologies that were eventually found in X-rays, the radio, and remote controls.
 

One thing he didn’t invent: A death ray. But try telling that to the Governor Clinton Hotel.

Tesla had financial problems later in life, and in 1915, his famous Wardenclyffe tower plant was sold to help pay off his $20,000 debt at the Waldorf-Astoria. By the 1930s, Tesla had again racked up a sizable bill at a hotel, this time the Governor Clinton Hotel in Manhattan. He couldn’t afford the payment, so instead, Tesla offered the management something priceless: one of his inventions. He told them the device—which he referred to as a death beam, not a death ray—was extremely dangerous, and could detonate if someone opened it without taking the proper precautions.

When Tesla died in 1943, an MIT scientist working for the National Defense Research Committee was sent to Tesla’s hotel room/lab to retrieve the potentially deadly weapon. Accompanied by the office of Naval Intelligence, John O. Trump later wrote in his FBI report that he took time to reflect upon his life before he opened the container.

He shouldn’t have bothered.

The only thing the wooden chest contained was a “multidecade resistance box of the type used for a Wheatstone bridge resistance measurements—a common standard item found in every electric laboratory before the turn of the century!”

In other words, Tesla threw some common electrical components in a fancy-looking box and convinced everyone it was a "death beam" worth $10,000. Tesla’s good friend, Mark Twain, would have been proud.

A Letter Written by Albert Einstein in 1922 Predicted the Rise of the Nazis

As a Jew living in Germany in the 1920s, Albert Einstein had an up-close view of the Nazis’ rise to power. As early as 1922, he could see turbulent political times ahead, as a letter to his sister reveals. The handwritten, signed letter recently sold at auction for $39,360, Live Science reports.

The letter, offered by the Jerusalem-based Kedem Auction House, is addressed to Einstein’s younger sister Maja. Einstein wrote it from an undisclosed location—probably Kiel, Germany, according to the auction house—after he fled Berlin in 1922 in the wake of the assassination of Germany’s Jewish foreign minister, Walther Rathenau, by a right-wing terrorist group. Police had warned Einstein that as a prominent Jew his life could be in danger, too. “Nobody knows where I am, and I'm believed to be missing,” he writes in the letter.

He remained upbeat while at the same time acknowledging the seriousness of the political situation that he and other German Jews were facing. “I am doing quite well, in spite of all the anti-Semites among my German colleagues,” he assured Maja. "Here are brewing economically and politically dark times, so I'm happy to be able to get away from everything for half a year,” he wrote, alluding to his upcoming six-month trip to Asia, during which he would learn that he had won the Nobel Prize. He was right—Adolf Hitler's failed coup in Bavaria would take place the next year, in November 1923.

Einstein goes on to say “Don't worry about me, I myself don't worry either, even if it's not quite kosher; people are very upset. In Italy, it seems to be at least as bad, by the way."

After his Asian tour, he returned to Germany before setting out on new travels, including a tour of the United States. He was in the U.S. when Adolf Hitler became Germany’s chancellor, and decided to renounce his German citizenship. He eventually settled in Princeton, New Jersey.

No Joe: The Time Coffee Was Banned in Prussia

In the late 18th century, Prussia's King Frederick the Great (officially Frederick II) blacklisted coffee and encouraged his royal subjects to drink something far more wholesome—beer. According to William Harrison Ukers's classic 1922 book All About Coffee, Frederick issued this decree on September 13, 1777:

"It is disgusting to notice the increase in the quantity of coffee used by my subjects, and the amount of money that goes out of the country in consequence. Everybody is using coffee. If possible, this must be prevented. My people must drink beer. His Majesty was brought up on beer, and so were his ancestors, and his officers. Many battles have been fought and won by soldiers nourished on beer; and the King does not believe that coffee-drinking soldiers can be depended upon to endure hardship or to beat his enemies in case of the occurrence of another war."

Though the authenticity of the above quotation cannot be confirmed, it certainly jibes with King Freddie's other opinions on the matter, according to Robert Liberles, a scholar of German-Jewish history. In a 1779 letter, Frederick wrote, "It is despicable to see how extensive the consumption of coffee is … if this is limited a bit, people will have to get used to beer again … His Royal Majesty was raised eating beer-soup, so these people can also be brought up nurtured with beer-soup. This is much healthier than coffee."

So Old Fritz, as he was called, loved beer. But why was he so opposed to coffee?

For one, Frederick was terrified that excessive imports could ruin his kingdom's economy, and he much preferred to restrict commerce than engage in trade. Since coffee, unlike beer, was brought in from across the border, Frederick regularly griped that "at least 700,000 thaler leave the country annually just for coffee"—money, he believed, that could be funneled into well-taxed Prussian businesses instead.

In other words, into Fritz's own pockets.

To redirect the people's spending patterns, Frederick ordered a number of steep restrictions, demanding that coffee roasters obtain a license from the government. This sounds like a reasonable regulation until you learn that Frederick summarily rejected nearly all of the applications, granting exceptions only to people who were already cozy with his court.

If that sounds elitist, it was. Frederick was adamant about keeping coffee out of the hands and mouths of poor people, writing, "this foreign product [has] extended into the lowest classes of human society and caused great contraband activities." To stop them, he hired approximately 400 disabled soldiers to work as coffee spies, or "sniffers," to roam city streets "following the smell of roasting coffee whenever detected, in order to seek out those who might be found without roasting permits," Ukers writes.

But none of these tactics worked. Rather, they just increased coffee smuggling and exacerbated the "contraband activities" that Frederick claimed he was trying to prevent in the first place. So shortly after the king died in 1786, many of these restrictions were lifted, proving yet again that it's always a mistake to get between someone and their java.
