TypewriterIn 1714, an idea for a possible typewriter predecessor was patented by Englishman Henry Mill, but he never succeeded in perfecting his invention and it died with him. Nothing more than the patent record remains known about the machine. It was British patent number 385, granted “by the grace of Queen Anne.” The patent's title was: An artificial machine or method for the impressing or transcribing of letters singly or progressively one after another, as in writing, whereby all writing whatever may be engrossed in paper or parchment so neat and exact as not to be distinguished from print. |
