French engineer who, in 1854, predicted the possibility of electric speech transmission (what will become later the telephone). Charles Bourseul experimented with the electrical transmission of the human voice and developed an electromagnetic microphone, but his telephone receiver was unable to convert electrical current back into clear human voice sounds. In 1854 Bourseul wrote a memorandum on the transmission of the human voice by electrical currents that was first published in a magazine L'Illustration (Paris), though no prototype was built. Bourseul explained: « Suppose that a man speaks near a movable disc sufficiently flexible to lose none of the vibrations of the voice; that this disc alternately makes and breaks the currents from a battery: you may have at a distance another disc which will simultaneously execute the same vibrations.... It is certain that, in a more or less distant future, speech will be transmitted by electricity. » |
