Clemens' pen name 'Mark Twain' is a nautical reference

Twain grew up in Missouri near the Mississippi River

When Twain (then known as Samuel Clemens) was 4 years old, his family moved to Hannibal, Missouri, a port town along the Mississippi River. Hannibal would eventually be the setting for two of his most famous works: “The Adventures of Huckleberry Finn” and “The Adventures of Tom Sawyer.”

As a child, Twain worked as a 'printer's devil'

Twain’s father died in 1847, forcing the 12-year-old Twain to leave school to earn money for the family. He took up work in a print shop as a “printer’s devil,” or an apprentice. He became fascinated with the technology, an experience he’d pursue further when he became a journalist several years later.

He was one of the first writers to cover surfing

For his 1872 travelogue “Roughing It”, Mark Twain visited Hawaii and described a then-peculiar sport: surfing. He even recalls his own attempts to catch a wave, writing, “I got the board placed right, and at the right moment, too; but missed the connection myself. The board struck the shore in three-quarters of a second, without any cargo, and I struck the bottom about the same time, with a couple of barrels of water in me.”

He made a name with a short story about jumping frogs

Twain’s first big break came with “Jim Smiley and His Jumping Frog,” a fictitious story that appeared in a 1865 edition of the New York Saturday Press. (When it was republished elsewhere, the title was changed to “The Celebrated Jumping Frog of Calaveras County.”) That year, American poet James Russell Lowe called it “the finest piece of humorous literature yet produced in America.”

Mark Twain spent decades feuding with the US Postal Service, convinced its costs and regulations were bureaucratic overreach.

Mark Twain once challenged a rival newspaper editor to a duel

While writing for a newspaper in Virginia City, Nevada, Twain published a story about a local fundraiser, accusing the paper’s rival of rescinding their donation. The problem was that the story was untrue: It was a hoax that he had concocted while drunk. The affair led to a protracted, public back-and-forth, with Twain challenging the editor of the rival paper to a duel; likewise, two other men challenged Twain to a duel. Twain ultimately left town, but wrote about the episode later on in an essay titled “How I Escaped Being Killed in a Duel.”

Twain claimed to possess 'mental telegraphy'

Dickens' earliest pieces were under the pseudonym 'Boz'

By the 1840s, he'd ditched the pseudonym, enjoying his rarefied literary celebrity.

Mark Twain coined the phrase 'The Gilded Age'

The writer's 1873 book "The Gilded Age: A Tale of Today" (cowritten with newspaper editor Charles Dudley Warner) satirized the speculative investing and greed that took place following the Civil War.

Why Thomas—an early alleged witness—was not a doubter, but an empiricist

Apologist Sean McDowell argues the label "Doubting Thomas" (a common name for the gospel figure who initially did not believe in Jesus' resurrection) is a mistranslation of his character. The Greek word for doubt means wavering, but Thomas didn't waver; he flatly refused to believe until he could physically touch the wounds.
