Jean-Maurice-Émile Baudot (1845-1903) patents the 5-bit Baudot code, the first binary character code for processing textual data, and printing telegraph, or teleprinter. Messages written on a teleprinter were created on two-channel transmission tapes, and then sent along a line using a miltiplex system allowing up to six operators to share the line.
