Samuel Clemens, better known by his pen name Mark Twain, was an early adopter of technology. He is widely believed to be the first author to submit a book manuscript to a publisher that was entirely typewritten. While there is some debate between 'Life on the Mississippi' and 'The Adventures of Tom Sawyer,' Twain himself claimed in his autobiography that he was the 'first person in the world to apply the type-writer to literature.' He purchased a Remington No. 1 in 1874. Twain was also a failed inventor who lost much of his fortune investing in a mechanical typesetter called the Paige Compositor. Despite his financial woes, his sharp wit and use of regional dialects in 'Huckleberry Finn' revolutionized American literature, moving it away from the rigid structures of European styles toward a more authentic American voice.
