Mark Twain was an American author born in 1835 in Missouri. He had experiences working as a steamboat pilot and journalist that influenced his writing. Two of his most famous works were The Adventures of Tom Sawyer and Adventures of Huckleberry Finn, which drew from his experiences growing up in Hannibal, Missouri and working on the Mississippi River. These novels typified Twain's style of writing realistically about things he knew firsthand. Even when writing other works set in different time periods and places, like The Prince and the Pauper, Twain drew from his own experiences of boys gradually losing their innocence.
