Henry Mill was an English inventor who patented the first typewriter in 1714. He worked as a waterworks engineer for the New River Company, and submitted two patents during his lifetime. One was for a coach spring, while the other was for a "Machine for Transcribing Letters". The machine that he invented appears, from the patent, to have been similar to a typewriter, but nothing further is known. Other early developers of typewriting machines include Pellegrino Turri. Many of these early machines, including Turri's, were developed to enable the blind to write.
