dc.descriptionEdison worked on automatic telegraphs between 1870 and 1874. He first developed an improved perforator with a keyboard similar to that of a typewriter that operated at about 35 words per minute. In 1874 he began to work on a multiplex telegraphic system for Western Union, ultimately developing a quadruplex telegraph, which could send two messages simultaneously in both directions.
