It is believed that Mark Twain was the first writer to submit a typewritten manuscript for publication. However, there is debate on which manuscript it was. Twain, himself, said that it was “Tom Sawyer.” Others say it was probably “Life on the Mississippi.”
He bought his first typewriter in 1874. He paid $125 for it. “The Adventures of Tom Sawyer” was published in 1876 and “Life on the Mississippi” was published in 1883.
