Abstract
Since Philipp Reis succeeded in sending human voices through electric wires well ahead of Elisha Gray and A. G. Bell etc., he deserves to be acknowledged as the inventor of the telephone. Nevertheless, he did not enjoy any honor for his great invention while he was alive. Since he was working in a scientific community, his work was presented not as a patentable invention but as a scientific discovery. In addition, he used the intermittent electricity in accordance with the experimental tradition in European acoustics, occasioning the speech quality of his telephone to have a fatal shortcoming. On the contrary, Bell, who was a novice in electricity and acoustics, employed variable currents to transmit the sound signals, which guaranteed better speech qualities than Reis's.
