Mark Twain, the pen name of Samuel Langhorne Clemens (1835–1910), stands as one of the greatest American authors, celebrated for his sharp wit, narrative prowess, and insightful commentary on human nature and society. Twain's literary career spanned several decades, during which he crafted stories that have entered the canon of classic American literature. Born in Florida, Missouri, Twain grew up along the banks of the Mississippi River, an environment that would later inform his most famous works, such as 'The Adventures of Tom Sawyer' (1876) and its sequel 'Adventures of Huckleberry Finn' (1885), the latter often referred to as 'The Great American Novel.' Twain's writing is characterized by its use of vernacular speech, humor, and social criticism, deftly woven into tales that both entertain and provoke thought. 'The Mysterious Stranger,' one of Twain's later works, delves into themes of existentialism and nihilism through a narrative that explores the nature of morality and the human condition. This posthumously published work exemplifies Twain's penchant for satire and philosophical inquiry, further cementing his reputation as a literary luminary. His contributions to literature extend beyond his novels and into numerous essays, short stories, and travelogues, showcasing his versatility and range as an author. Twain's legacy endures, influencing writers and captivating readers more than a century after his passing.
