The deaths of Thomas Jefferson and John Adams - Thomas Jefferson and John Adams both helped draft and signed the Declaration of Independence, and though they became political rivals with their Republican and Federalist divide—particularly after Jefferson succeeded Adams as president in 1801—they reconciled in 1812 and had a beautiful friendship and correspondence until their coincidental deaths.

The deaths of Thomas Jefferson and John Adams -

On July 4, 1826, coincidentally as the country celebrated the 50th anniversary of American independence, 83-year-old Jefferson passed away at his Virginia estate, Monticello. The 90-year-old Adams, unaware of his friend’s death while on his own deathbed in Quincy, Massachusetts, reportedly whispered a few last words: “Thomas Jefferson survives.” The friends died mere hours apart.

Dennis the Menace -

On March 12, 1961, a character named Dennis the Menace debuted twice, on either sides of the Atlantic, mere hours apart, and by two people who had never met.

Dennis the Menace -

The UK comic by David Law first appeared in The Beano, and the US comic by Hank Ketcham was published as a syndicated newspaper comic strip. The two creators had no idea what the other was working on, and in fact the characters are quite different, as the British Dennis was more mean-spirited and the US version was a happy-go-lucky type who caused trouble without meaning to. The characters were made independently but simultaneously.

Tsutomu Yamaguchi survives two atomic bombs -

The historic nuclear blasts the US delivered to the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, are infamous for how many deaths they caused from both the blast and the radiation afterwards, killing nearly 90,000 people. But in 2009, the Japanese government confirmed that one man survived both blasts.

Mark Twain’s cosmic entrance and exit -

Halley’s Comet is a periodic comet that returns to Earth’s vicinity around every 75 years, and it was in the sky when famed author Mark Twain, originally Samuel Langhorne Clemens, was born on November 30, 1835. By 1909, 74 years had passed, and Twain was quoted as saying, “It will be the greatest disappointment of my life if I don’t go out with Halley’s Comet.”

Mark Twain’s cosmic entrance and exit -

Twain continued, “The Almighty has said, no doubt: ‘Now here are these two unaccountable freaks; they came in together, they must go out together.’” Then on April 21, 1910, the day after Halley’s Comet emerged from the far side of the sun, Twain died suddenly of a heart attack.

“Miss Unsinkable” Violet Jessop -

Born in Argentina to Irish immigrants, Violet Jessop became a ship stewardess at 21 to provide for her family. She ended up working for White Star, which launched its trio of gigantic luxury liners—the Olympic, the Titanic, and the Britannic—in 1911. All three ships faced disaster, but Jessop lived to tell the tale.

“Miss Unsinkable” Violet Jessop -

Jessop was serving aboard the Olympic when the liner collided with the HMS Hawke near the Isle of Wight, in southern England. She then moved to the Titanic in time for its disastrous maiden voyage in 1912, and was one of the people who made it onto a lifeboat. Jessop later became a nurse in the British Red Cross and was serving on the Britannic, which was used as a hospital ship after World War I, in 1916 when the ship struck a mine in the Aegean Sea. The ship sank but only 30 people died, and Jessop survived again. “Miss Unsinkable” reportedly continued working on cruise ships after the war.

Bobby Farrell, a member of German-Caribbean disco group Boney M., reached fame with his bandmates for the disco ballad ‘Rasputin,’ which sings of a debauched Russian mystic healer, renegade monk, and known sexual deviant who was murdered on December 30, 1916, in St. Petersburg.

The death of Bobby Farrell -

The song was such a smash hit that the band was still performing it in 2010. But one fateful morning, after Boney M. had performed a set that included ‘Rasputin,’ 61-year-old Bobby Farrell was found dead in his hotel room on December 30—the anniversary of the "Mad Monk's" death—and in St. Petersburg, no less.

Stephen Hawking’s death -

Stephen Hawking had strong theories about the peculiarity of time, but perhaps not even he could predict that the day he was born and the day he died would link him in time with two other historical geniuses that helped pave the way for a mind like his.

Stephen Hawking’s death -

Hawking was born exactly 300 years to the day of Galileo's death (January 8), and he died on March 14, 2018, which not only coincides with Albert Einstein's 139th birth anniversary, but also what is known as “Pi Day,” as the date 3/14 coincides with the first three digits of pi.

Life imitates art -

In Edgar Allan Poe’s 1838 novel ‘The Narrative of Arthur Gordon Pym of Nantucket,’ a ship’s crew ends up in a desperate situation, and they eventually draw straws to decide who among them will be the next life-sustaining meal. The unlucky character who gets eaten is named Richard Parker, and the characters also eat a tortoise. A few decades later, the story came to fruition.

Life imitates art -

Some 50 years later, a real-life yacht called the Mignonette sank and the four-man crew escaped on a dinghy with little provisions. They ended up eating a tortoise, and then in desperation resorted to eating one of their own, just like Poe's story. Even weirder, the unlucky man who was eaten was named Richard Parker!

The sandwich that changed everything -

The assassination of Archduke Franz Ferdinand is said to have been the launch point for WWI, but what most don’t know is that a stop at a café for a sandwich is the only reason the assassins were given a second attempt. Their original attempt to kill the archduke failed as the bomb hit the car behind Ferdinand’s and he escaped unscathed. Upset, one of the assassins stopped to get a sandwich at a nearby café...

The sandwich that changed everything -

The archduke hurried off in his car, but his driver made a wrong turn and happened to pass right by the café where the attacker was getting a sandwich. He took his second chance and shot the archduke and his wife. The assassin then took a cyanide pill, but it only made him sick, and he went to jail where he died four years later from tuberculosis.
