James C. Marsters
James Carlyle Marsters (April 5, 1924 – July 28, 2009) was a deaf American orthodontist. In 1964, he helped invent the first teletypewriter device that could be used with telephone lines. The device let deaf people communicate by telephone. Although Robert Weitbrecht did much of the actual design work, Marsters promoted the device's use.
