Mark Twain (Samuel Clemens): Biography and Pseudonym Origin

Samuel Langhorne Clemens (1835‑1910), better known by his pen name Mark Twain, was an American writer, humorist and satirist whose works such as *The Adventures of Tom Sawyer* and *The Adventures of Huckleberry Finn* remain central to the U.S. literary canon. He was born in Florida, Missouri, and later worked as a steamboat pilot on the Mississippi River, an experience that shaped his writing.

The name "Mark Twain" comes from river‑navigation slang meaning a safe depth of two fathoms (about 3.7 m) on the Mississippi, reflecting Clemens’s familiarity with the river and its culture. He adopted the pseudonym to evoke the adventurous, river‑bound world that features prominently in his stories. Clemens died in Redding, California, but his books continue to be read worldwide and are standard in school curricula.
