Samuel Langhorne Clemens, better known by his pen name of Mark Twain, is one of the most famous writers in American (and world) literature. Twain had a fascinating life that began in hardship in 1835 (only three of his seven siblings survived childhood) and ended shortly before the First World War. Best known for his writing, Twain was also a gifted raconteur, entrepreneur, publisher, freemason, and lecturer across a very busy life that saw him patent inventions, go bankrupt and receive a PhD from Oxford University, all the while putting out an enormous volume of superbly written literary work.
