James Carlyle Marsters (April 5, 1924 – July 28, 2009) was a deaf orthodontist in Pasadena, California who in 1964 helped invent the first teletypewriter device capable of being used with telephone lines. The device made communication by telephone possible for the deaf. Although Robert Weitbrecht did much of the actual design work, Marsters promoted the device's use.
