Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), more widely known as Mark Twain, was a well known American writer born in Florida, Missouri. He worked mainly for newspapers and as a steamboat pilot on the Mississippi River before he became a writer. He married in 1870, and raised his family in Hartford, Connecticut. In later life he invested and lost the money that his writing had made, and toured the world giving lectures that brought him enough money to pay his debt and recover his fortune.
