Acknowledgement

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 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.

Dr. Robert H. Weitbrecht,

1920–1983, inventor of the

first TTY modem.
