A Teletype model 33

Date Invented: 1849 [1]

Inventors:  Royal Earl HouseDavid Edward HughesEmile BaudotDonald MurrayCharles L. KrumEdward Kleinschmidt and Frederick G. Creed, all worked on the project and through many evolutions came up with the final teleprinter. [1]

Uses: The teleprinter was originally used in the military to replace the need for operators to know Morse code, however the deaf community saw its potential and used it for long distance communication that was, compared to letters, almost instantaneous. [2]

How does it work: The teleprinter used the phone system to relay messages across long distances, this was done by having two machines set up at different location, and then having the operators or user simply type their message to the other user. Then the message would be sent and received by the machine at the other end and this machine would print the message using a printer that was built into the machine. [3]

Impact on Deaf Community: The teleprinter could be considered the precursor to the modern TTY, and it gave the Deaf community a way to communicate over long distances at any given moment. If there was a teleprinter available a deaf person could use it to send a message to a family member or friend whenever they wanted to. In addition if the person at the receiving end of the message had a teleprinter as well there was no communication barrier, so a deaf person could communicate with anyone whenever they wanted to deaf or hearing.
