Author and humorist Samuel Langhorne Clemens, or as he is better known, Mark Twain used his home town of Hannibal, Missouri as the backdrop for his two most notable works: The Adventures of Tom Sawyer and, Adventures of Huckleberry Finn (which has often been referred to as the Great American Novel). He tried a number of other career options before discovering his true vocation. He was an apprentice printer, a typesetter, a riverboat pilot, a gold miner, inventor, and finally a journalist. He was a Jack of all trades, who could never master his finances, though he always made sure his debts were eventually paid, but when it came to writing he certainly excelled. He became well known for his works, was acclaimed by his peers, and counted presidents and industrialist and other notables amongst his friends.
