EL RINCÓN DEL FRIKI:THE HISTORY AND DEVELOPMENT OF TYPEWRITERS Tilghman Richards, G.

This Handbook of the National Collection of Typewriters illustrates in considerable detail how the evolution of the modern machine has come about from the early trials and struggles of many inventors. In the early days the urge to provide writing machines for the use of blind persona was one of the main factors in experimental development. This desire seems to have been particularly active in the late eighteenth and early nineteenth centuries, when some twenty-three different methods of making embossed printing were in existence, of which the best known were those devises by Lucas, Frere. Moon, and Braille. The latter published his system in 1829 and developed in further in 1834. It was officially recognised is Paris in 1854.
