Question: What was the first typewritten manuscript submitted for publication?
Answer: Life on the Mississippi (1883) by Mark Twain
Twain receives the credit for having dictated the book to a secretary, although this is not so much a verified fact as a claim found to be the most plausible case for first such use of the typewriter.
