Which author was the first to write a book on a typewriter?

Senior Moments

Among the first was Mark Twain, who bought a typewriter the moment he saw one. Twain only played with the machine, and never used it to do any writing. Instead, he paid professional typists to transcribe his manuscripts, and so became the first author to send a novel (Life On The Mississippi in 1883) to a publisher in typed form. Years earlier, however, Victorian actress Fanny Kemble used her Sholes and Glidden to crank out copy for a column in Atlantic Monthly, which gives her the distinction of being the first known writer to use a typewriter. - http://popularmechanics.com/popmech/spec/9608SFACM.html Jul 02 02, 7:22 PM
