Acknowledgement
In 1963, Dr. Robert H.Weitbrecht, an
American physicist who was deaf, devel-
oped 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 microcom-
puter devices like your new Ultratec
text telephone, the Weitbrecht modem
remains the major technological break-
through 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.
