Samuel Langhorne Clemens, better known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher, and lecturer, born on November 30, 1835, in Florida, Missouri. Twain grew up in Hannibal, Missouri, which later provided the backdrop for 'The Adventures of Tom Sawyer' and 'The Adventures of Huckleberry Finn'. His literary works are lauded for their wit, satire, and keen observation of American life. The 'The Complete Huckleberry Finn & Tom Sawyer Adventures (Unabridged)' encompasses Twain's most famous characters and narratives, drawing from his childhood experiences along the Mississippi River. Considered one of the first major authors to come from the interior of the country, Twain influenced the American literary canon with his vernacular writing style and biting social commentary. His works not only capture the complexities of race, class, and societal norms but also reflect his multifaceted life as an inventor, riverboat pilot, and world traveler. Twain's writing remains a cornerstone of American literature, often required reading in educational curricula. The significance of Twain's contribution to the literary world was such that he was awarded honorary doctorates by Yale University, the University of Missouri, and Oxford University. Mark Twain passed away on April 21, 1910, but his literary legacy continues to enliven the minds of readers around the world.
