French inventor Emile Baudot (baw-DOH) developed the Baudet code, a five-bit binary system that could map complete phrases as single coded words. This made his system economical and efficient for telegraphy and telex transmissions, and allowed Baudet Code, introduced in 1874, to quickly supersede and replace Morse code. Baudet's system was the international standard in surface and undersea telegraph and telex communications until the early 1930s, but faded from use as new, higher-tech forms of communications were introduced. It has reflourished in telecommunications devices for the deaf (TDDs) and some ham radio applications.

Baudot also invented multiplex printing telegraphs with, first, the ability to transmit two messages at once, and eventually the ability to concurrently send separate messages from six senders to six recipients, over one set of wires. Remarkably, he had only a grade school education, no pertinent training and no noted mechanical inclination, before he was hired by the French Administration of Posts and Telegraphs in 1869. He worked for the agency until his death in 1903. The word "baud", the measure of symbols or data transmitted per second, was coined in 1926 to honor Baudot's work.
