Mark Twain

In “Green Hills of Africa,” Ernest Hemingway declared that all modern American literature sprang from Twain's "Adventures of Huckleberry Finn." That’s a sentiment shared by many scholars, who assert that Twain’s book changed American fiction by challenging the country’s racist history and incorporating a more realistic vernacular.

Twain’s childhood hometown of Hannibal, Missouri, attracts countless tourists seeking Twain-themed reenactors and museums. Ron Chernow, author of a 2025 about the writer, argues that the ongoing interest in Hannibal and in Twain’s writing is because his work and life typify the American experience.

Twain’s books are in the public domain, meaning they can be freely distributed. Digital versions of his classic novels—including “The Adventures of Huckleberry Finn,” “The Adventures of Tom Sawyer,” “A Connecticut Yankee in King Arthur’s Court”—as well as many of his short stories and satirical essays can be accessed through Project Gutenberg.

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.”

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.

In 1861, a 25-year-old Twain joined the Marion Rangers, a pro-Confederate militia. The group disbanded after two weeks upon hearing that Ulysses S. Grant, General of the Union Army, was headed their way. Twain moved to Nevada, where he eventually took a job at a newspaper.

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.”

Samuel Clemens became a steamboat pilot’s apprentice in 1857 while writing a travelogue for a small newspaper, and earned his pilot’s license two years later. During that time, he learned the term “mark twain,” which meant 12 feet, something shipworkers would yell when they were approaching shallow waters. In 1861, he signed a travel letter under the pseudonym “Mark Twain” and used it for the rest of his career.

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.”

Ever the ironist, Twain claimed to have “ no liking for novels or stories.” Obviously, that was untrue: He read widely, devouring books by Charles Dickens, slave narratives, and texts on astronomy. He also loved John Milton’s “Paradise Lost,” which he called “something everybody wants to have read and nobody wants to read.”
