The Diplograph was invented ca.1875 by Ernest Recordon of Geneva, Italy. This typewriter was unique because it was capable of typing both braille and text at the same time. The Diplograph's two concentric typewheels executed this task on separate sheets of paper. Diplograph translates to two pens. The typewriter was produced by Société Genevoise d'Instruments de Physique (SIP) in Geneva, Switzerland.
