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 text
telephone, 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.
