Mark Twain, the author of 'The Adventures of Huckleberry Finn,' was an early adopter of technology and is often cited as the first author to submit a typewritten manuscript to a publisher. In his autobiography, Twain claimed that 'Life on the Mississippi' (published in 1883) was the first book ever typed on a machine. He used a Remington No. 1, which only printed in capital letters. Although he found the machine frustrating at first—complaining that it was 'corrupting his morals' because it made him want to swear—he recognized its potential for speed and clarity. Twain’s embrace of the typewriter marked the beginning of a major shift in the literary world, moving away from longhand calligraphy to the mechanical efficiency that would define 20th-century writing.
