Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910),[1] better known by his pen name Mark Twain, was an American author and humorist. Among his writings are The Adventures of Tom Sawyer (1876) and its sequel, Adventures of Huckleberry Finn (1885),[2] the latter often called "The Great American Novel".

Twain was raised in Hannibal, Missouri, which later provided the setting for Tom Sawyer and Huckleberry Finn. After an apprenticeship with a printer, Twain worked as a typesetter and contributed articles to the newspaper of his older brother, Orion Clemens.

Twain moved to San Francisco in 1864, still as a journalist, and met writers such as Bret Harte and Artemus Ward. The young poet Ina Coolbrith may have romanced him.

Twain was fascinated with science and scientific inquiry. He developed a close and lasting friendship with Nikola Tesla, and the two spent much time together in Tesla's laboratory.

Twain patented three inventions, including an "Improvement in Adjustable and Detachable Straps for Garments" (to replace suspenders) and a history trivia game.[35][36] Most commercially successful was a self-pasting scrapbook; a dried adhesive on the pages needed only to be moistened before use.[35] Over 25,000 were sold.[

Twain's novel A Connecticut Yankee in King Arthur's Court (1889) features a time traveler from the contemporary US, using his knowledge of science to introduce modern technology to Arthurian England. This type of storyline would later become a common feature of a science fiction subgenre, alternate history.

In 1909, Thomas Edison visited Twain at his home in Redding, Connecticut and filmed him. Part of the footage was used in The Prince and the Pauper (1909), a two-reel short film. It is said to have been the only known existing film footage of Twain.
