In 1963, Dr. Robert H.Weitbrecht,an American
physicist who was deaf, developed an acoustic coupler
that could send and receive teletypewriter signals
over the telephone lines. His invention,the Weitbrecht
Modem, enabled people who are deaf to use the
telephone for the first time.While modern
technology now makes it possible to build advanced
microcomputer devices like your new Ultratec TTY,
the Weitbrecht modem remains the major
technological breakthrough that began
telecommunications for the deaf.Ultratec wishes to
acknowledge the importance of Dr.Weitbrecht’s
contribution to the welfare of people who are deaf
the world over.
Dr. Robert H. Weitbrecht,
1920–1983, inventor of the
first TTY modem.
