(1835-1910) Mark Twain, whose real name was Samuel Langhorne Clemens, was an American writer, humorist and lecturer, considered one of the greatest authors of English-language literature. He was born in Florida, Missouri, and grew up on the banks of the Mississippi River, which profoundly influenced his most famous works, The Adventures of Tom Sawyer and The Adventures of Huckleberry Finn, which explore themes such as childhood, friendship, and racial tensions in 19th century America. Twain was also an astute social critic who used humor and satire to address political and cultural issues of his time. Throughout his life, he experienced periods of literary success and great financial hardship, which led him to take a deep and often critical view of society. Twain remains an iconic figure both for his literary style and for his ability to blend humor with profound reflections on the human condition.
