Biography/Organization History
Robert H.
Weitbrecht
was a physicist and electronic design engineer best known for his invention of TTY, also known as the teletypewriter, TDD,
or Telecommunication Device for the Deaf. Weitbrecht, born deaf in 1920, became interested in amateur radio as a young man,
eventually constructing his own ham radio set at the age of 13. The set allowed him to decipher Morse code messages received
by means of amplified ear phones that produced vibrations that enabled him to distinguish the codes. By college, Weitbrecht
had become licensed as a ham radio operator by the Federal Communications Commission. He was thought to be the only deaf amateur
radio operator in the world in the late 1930s. Weitbrecht attended Santa Ana Junior College from 1938 to 1940 and then enrolled
in the University of California, Berkeley. He received his bachelor's degree in Astronomy in 1942. During World War II, Weitbrecht
worked at UC Berkeley on Cyclotron Hill at the Radiation Laboratory. After the war, he moved to the U.S. Naval Air Missile
Test Center at Point Mugu, California, where he spent four years developing electronic timing systems for the missle range
instrumentation. It was during these years that Weitbrecht became acquainted with the Teletype Model 15. In 1950, Weitbrecht
obtained his own radio teletypewriter and began experimenting with the machine in his amateur radio pursuits. In 1951, Weitbrecht
moved to Wisconsin to work at Yerkes Observatory and, in his spare time, continued to develop electronic equipment for radio
teletypewriter communication. While in Wisconsin, Weitbrecht obtained a master's degree from the University of Chicago in
Astronomy. In 1957, he moved to Stanford University, where he worked as a physicist at Stanford Research Institute (SRI) in
Menlo Park. He remained with SRI for eleven years. It was during this time that Weitbrecht designed and built cameras and
electronic equipment for the Lick Observatory. In 1964, he met some members of the Alexander Graham Bell Association for the
Deaf and Hard of Hearing and, with their encouragement, started determining how to adapt the teletypwriter into an assistive-listening
device for the deaf community by figuring out how to make it work on a regular telephone line. In 1964, he developed the acoustic
coupler that allowed the teletypewriter to be used with a telephone. This coupler eventually became known as the Weitbrecht’s
Modem. Weitbrecht's companies specializing in the distribution of TTYs and other assistive listening devices included the
R.H. Weitbrecht Company, Applied Communications Corporation, and Weitbrecht Communications.
Scope and Content Note
Collection consists of 5 series: Business and Professional Correspondence, Subject Files, Personal Papers and Correspondence,
Publications and Manuals, and Patent Files. The business and professional correspondence is mostly Weitbrecht's work-related
correspondence dating from the founding of his company, the R.H. Weitbrecht Company, in the middle of the 1960s to circa 1982.
The subject files date from 1953 to 1982 and include files on topics relating to Weitbrecht's research and his personal interests.
The personal papers and correspondence consist of a small amount of personal correspondence as well as an autobiographical
sketch, some writings, drawings, and school work. The publications and manuals include technical manuals and bulletins. The
patent files consist of files of patent documents and correspondence relating to Weitbrecht's inventions.
