StenotypeIn 1876, the stenotype was patented by John C. Zachos of New York City (No. 175,892). This was the first U.S. patent for a device for printing legible text in the English alphabet at a high reporting speed, which he called a "typewriter and phonotypic notation." The type was fixed on eighteen shuttle bars, two or more of which may be simultaneously placed in position. The impression was given by a plunger common to all bars. He called his new system of shorthand "stenophonotypy."* |
