Robert Haig Weitbrecht was an engineer at SRI International and later the spin-off company Weitbrecht Communications who invented the teleprinter and the modem (a form of acoustic coupler).
Weitbrecht was born in Orange, California in 1920. 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.
Weitbrecht was initially a physicist at the Radiation Laboratory at the University of California (now Lawrence Livermore National Laboratory), then an electronics scientist at the U.S. Naval Air Missile Test Center. He was a contributing engineer to the Manhattan Project, where he developed the modern Geiger counter; for his efforts, he earned the United States Navy's Superior Accomplishment Award.
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).
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. 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 now? Let's quit for now and gloat over the success." Today, this type of device is known as a telecommunications device for the deaf.
