Are You Smart Enough to Pass Thomas Edison's Impossible Employment Test?

If you thought Elon Musk's favorite question to ask job applicants was tough, you should see the employment test devised by Thomas Edison. When he wasn't busy inventing the light bulb or phonograph, or feuding with Nikola Tesla, Edison was apparently devising a trivia test of nearly impossible proportions.

As Smithsonian reports, the 146-question quiz was designed to weed out the candidates who would be ill-suited to work at his plant, which was a desirable place to get a job in 1921. College degrees didn't impress him much—"Men who have gone to college I find to be amazingly ignorant," he once remarked—so he needed to find a more effective method of determining prospective employees' knowledge.

The test may have been too effective, though. Of the 718 applicants who took the test, only 57 achieved a passing score of 70 percent, and only 32 scored Edison's desired result of 90 percent or higher. This was certainly frustrating to applicants who considered themselves to be pretty well-educated. An unsuccessful applicant named Charles Hansen, who shared all of the questions he remembered with The New York Times in 1921, called the test a "silly examination." Another applicant said it was "not a Tom Edison but a Tom Foolery test" [PDF].

After the test questions became public knowledge, reporters went out and started polling people to see how well they'd do on Edison's test. Albert Einstein reportedly failed (he didn't know the speed of sound offhand), as did Edison's youngest son, who was a student at MIT at the time.

If you want to challenge yourself, check out a few of the questions below, then scroll down to see the answers that appeared in The New York Times. (Note: The answers given were the correct answers in 1921, but some may have changed since then. Some questions and answers have been edited lightly for clarity.)

1. What city in the United States is noted for making laundry machines?

2. In what country other than Australia are kangaroos found?

3. What region do we get prunes from?

4. Name a large inland body of water that has no outlet.

5. What state is the largest? The next?

6. What is the name of a famous violin maker?

7. What ingredients are in the best white paint?

4. The Great Salt Lake, for example

5. Texas, then California (Note: Today it's Alaska, then Texas)

6. Stradivarius

7. Linseed oil, with a small percentage of turpentine and liquid dryer, together with a mixture of white lead and zinc oxide

8. The gravitational pull of the moon exerted powerfully on the ocean because of its fluidity, and weakly on the Earth because of its comparative rigidity.

9. To the inclination of the Earth to the plane of the ecliptic. In the Earth's revolution around the Sun, this causes the Sun's rays to be received at varying inclinations, with consequent variations of temperature.

10. Roald Amundsen, and then Robert Falcon Scott

11. Approximately 186,700 miles a second in a vacuum and slightly less through atmosphere.

12. Ash is generally used in the East and hickory in the West.

13. No cereal is used in all parts of the world. Wheat is used most extensively, with rice and corn next.

14. Cyanide of potassium, strychnine, and arsenic are all acceptable answers.

15. It is named after Gabriel Daniel Fahrenheit, the German physicist who invented it.

Why Do We Eat Pumpkin Pie at Thanksgiving?

While it’s possible—even probable—that pumpkins were served at the 1621 harvest festival that’s now considered the predecessor to Thanksgiving, attendees definitely didn’t dine on pumpkin pie (there was no butter or wheat flour to make crust).

The earliest known recipes for pumpkin pie actually come from 17th-century Europe. Pumpkins, like potatoes and tomatoes, were first introduced to Europe in the Columbian Exchange, but Europeans were more comfortable cooking with pumpkins because they were similar to their native gourds.

By the 18th century, however, Europeans on the whole lost interest in pumpkin pie. According to HowStuffWorks, Europeans began to prefer apple, pear, and quince pies, which they perceived as more sophisticated. But at the same time pumpkin pie was losing favor in Europe, it was gaining true staple status in America.

In 1796, Amelia Simmons published American Cookery, the first cookbook written and published in the New World colonies. Simmons included two recipes for “pompkin pudding” cooked in pastry crust. Simmons’s recipes call for “stewed and strained” pumpkin, combined with a mixture of nutmeg, allspice, and ginger (yes, it seems our pumpkin spice obsession dates back to at least the 1500s).

But how did pumpkin pie become so irrevocably tied with the Thanksgiving holiday? That has everything to do with Sarah Josepha Hale, a New Hampshire-born writer and editor who is often called the “Godmother of Thanksgiving.” In her 1827 abolitionist novel Northwood, Hale described a Thanksgiving meal complete with “fried chicken floating in gravy,” broiled ham, wheat bread, cranberry sauce, and—of course—pumpkin pie. For more than 30 years, Hale advocated for Thanksgiving to become a national holiday, writing regular editorials and sending letters to five American presidents. Thanksgiving was a symbol for unity in an increasingly divided country, she argued [PDF].

Abraham Lincoln eventually declared Thanksgiving a national holiday in 1863 (to near-immediate outcry from Southerners, who viewed the holiday as an attempt to enforce Yankee values). Southern governors reluctantly complied with the presidential proclamation, but cooks in the South developed their own unique regional traditions. In the South, sweet potato pie quickly became more popular than New England’s pumpkin pie (mostly because sweet potatoes were easier to come by than pumpkins). Now, pumpkin pie reigns supreme as the most popular holiday pie across most of the United States, although the Northeast prefers apple and the South is split between apple and pecan, another Southern staple.

Anthony Blunt: The Art Historian/Russian Spy Who Worked at Buckingham Palace

*Mild spoilers for season 3 of The Crown on Netflix ahead.

Viewers of the third season of The Crown on Netflix will likely have their curiosity piqued by Anthony Blunt, the art historian who is revealed to be a spy for the Russians during his 19 years of service to the Queen at Buckingham Palace. Instead of getting the boot once he was discovered, however, Blunt went on to remain under Her Majesty's employ for eight more years—until his official retirement. While treason never looks good on a resume, the royal class had good reason to keep him on.

Blunt, who was born and raised in England, visited the Soviet Union in 1933 and was indoctrinated as a spy after being convinced of the benefits of Communism in fighting fascism. He began recruiting his university classmates at Cambridge before serving during World War II and leaking information about the Germans to the KGB. Blunt was one of five Cambridge graduates under Soviet direction. Two of them, diplomats Donald Maclean and Guy Burgess, relocated to the Soviet Union in 1951. Another, Kim Philby, went undetected until 1961. John Cairncross escaped notice, too, but was eventually outed.

However, it was Blunt who had a post at Buckingham Palace. After being tipped off by American intelligence, MI5 interrogated Blunt. He confessed to his treachery in 1964 and was granted immunity from prosecution. Why was he able to remain employed? One theory has it that British intelligence was so embarrassed by Blunt's ability to circulate in the upper levels of the monarchy that firing him would have raised too many questions. Another thought has Blunt having knowledge of some bizarrely congenial wartime correspondence between Adolf Hitler and the Duke of Windsor (a.k.a. King Edward VIII, whose abdication led to Elizabeth's eventual ascension to the throne).

Whatever the case, the Queen was advised by MI5 to keep Blunt around. In his role as art curator, he had no access to classified information. Blunt was at the Palace through 1972 and spent another seven years roaming London giving lectures. His actions remained a tightly guarded secret until Margaret Thatcher disclosed his treason in 1979.

As for that speech seen in The Crown, where Olivia Colman's Queen Elizabeth makes some not-so-subtle digs at Blunt at the opening of a new exhibition, there's no record of such a takedown ever happening. While the two reportedly kept their distance from each other in private, according to Miranda Carter's Anthony Blunt: His Lives:

“Blunt continued to meet the Queen at official events. She came to the opening of the Courtauld’s new galleries in 1968, and in 1972 she personally congratulated Blunt on his retirement, when the Lord Chamberlain, knowing nothing of his disgrace, offered him the honorary post of Adviser on the Queen’s pictures—inadvertently continuing his association with the Palace for another six years.”

Stripped of his knighthood as a result of the truth about his actions being made known, Blunt became a recluse and died of a heart attack in 1983. His memoirs, which were made public by the British Library in 2009, indicated his regret, calling his spy work "the biggest mistake of my life."
