Robert Haig Weitbrecht was born in Orange, California in 1920.[1] He was born deaf and his education was mainstream for the most part with the exception of acquiring some signing and lip-reading skills from a deaf school early on. He went on to earn a B.S. in Astronomy from the University of California, Berkeley in 1942 and finished his formal education with a M.S. in Astronomy from the University of Chicago in 1957. The title of doctor was bestowed on Robert Weitbrect in 1974 by Gallaudet University. Weitbrecht was a contributing engineer to the Manhattan Project.
Even in his high school days, Weitbrecht was interested in amateur radio and used radiotelegraph to communicate with fellow radio operators around the country. In 1964, this love for communication came together with the need to interact with a colleague who could not operate an amateur radio. To solve this problem, Weitbrecht created a device that used the public telephone system to achieve communication: the teletypewriter (TTY).[1] After being approached by James C. Marsters, Weitbrecht came up with a revised design for the acoustic coupler (now called a modem), which used echo suppression.[2] In 1964, Marsters and Weitbrecht adapted used teletypewriter equipment, and Weitbrecht made the first successful teletypewriter phone call from one deaf person to another. It took several tries, until Weitbrecht's words appeared clearly: "Are you printing me now? Let's quit for now and gloat over the success."[3] Today, this type of device is known as a Telecommunications Device for the Deaf.
Dr. Weitbrecht earned a pilot's license in 1967.[4]
Dr. Weitbrecht died after being involved in an automobile accident in 1983.[1]
