More than 100 years after the invention of the telephone, deaf and hard of hearing people could finally make a telephone call to anyone. Today, TTY relay services, the original and now “traditional” relay service, can be reached by anyone by dialing 711 from a telephone or TTY.

Teleprinters were invented in order to send and receive messages without the need for operators trained in the use of Morse code. A system of two teleprinters, with one operator trained to use a keyboard, replaced two trained Morse code operators.

Jan 12, 2016 · In the mid 1970s, as a young audiologist working in a university aural rehabilitation clinic, I inherited an old TTY. ‘Old’, at the time, was 1960s technology that cost between $650 and $1000, making it a luxury item that very few deaf individuals could afford.

Sep 23, 2024 · While his invention revolutionized communications, it wasn’t until the 1960s that a deaf inventor would develop a device to facilitate communication for non-hearing persons. The device became known first as the teletypewriter, later teletype or TTY.

With the help of groups such as TDI and similar local groups promoting the use of TTYs, Weitbrecht’s invention helped open a new world of communication to the deaf. This collection covers a period up to early 1980s and the introduction of relay services, which allowed TTY users to communicate with non-users. Scope and Content

In 1963, Marsters approached Dr. Robert Weitbrecht (1920-1983), a physicist and ham radio teletype (RTTY) enthusiast, to design an adapter that would allow TTYs to communicate over ordinary phone lines.

Feb 17, 2012 · During the late 1960s, Paul Taylor combined Western Union Teletype machines with modems to create teletypewriters, known as TTYs. He distributed these early, non-portable devices to the homes of many in the Deaf community in St. Louis, Missouri. He worked with others to establish a local telephone wake-up service.

TDI was known as the Telecommunications for the Deaf and Hard of Hearing, Inc. and was established in 1968 originally to promote further distribution of TTYs in the deaf community and to publish an annual national directory of TTY numbers.

Last week we began a discussion of the development of the TTY, invented by Robert H. Weibrecht (1920-1 983), and initially developed in the early 1960s. At the time, the TTY was a large, cumbersome, and somewhat frustrating device to use.

After more correspondence, Marsters pur- chased a Western Union 32ASR TTY. He con- tinued to encourage Weitbrecht, and in November 1963, Weitbrecht invented an acoustic coupler modem* that permitted him to communicate with Marsters over the voice-grade telephone lines by typing from his TTY to a similar unit in Marsters’ home.
