Twain wrote in his 1904 autobiography that his first novel written on a typewriter—the first typewritten novel at all—was Tom Sawyer. Twain purchased his first typewriter (which probably looked like the Remington Sholes and Glidden above) in 1874 for $125. In 1875, he writes in a letter to the Remington company that he is no longer using his typewriter; it corrupts his morals because it makes him want to swear. He gives the infernal machine away, twice. It returns to him each time.
