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 text telephone modem.
