Charles Thurber

Born 2 Jan 1803; died 7 Nov 1886 at age 83.American inventor of an early form of typewriter. He formed Allen & Thurber (Worcester, Mass) with his brother in law, Ethan Allen to manufacture firearms.

The type wheel was revolved until the desired lever came over the guide. The key was then forced down with the finger, and the character was printed.” Thurber also patented a different machine which he called the Chirographer, “for writing or forming any kind of figures or characters on paper, and making copies thereof at the same operation,” but the machine was still far too slow to substitute for hand writing.«
