Summary
A man with an ear for music thought he could build a "harmonic telegraph." He thought this would be possible because he had misinterpreted the writings of a researcher writing in German - a language he did not know. This program profiles Alexander Graham Bell and his work on telephony. The big question is: what happens in that wire? Bell and his assistant ultimately proved that different tones would vary the strength of an electric current in a wire. Eventually, the telephone - or better said, its wiring - leads to the Internet and the wireless communication of today. Looking to the future, are we headed toward a "phoneless" call?
