Aid To Wireless Telephony.

New York Times 100 years ago today, September 28, 1912:
Sparkless Invention May Make Long Distance Talking Easy.
Special Cable to The New York Times.
    PARIS, Sept. 27.— Edouard Branly, a pioneer in wireless telegraphy, was interviewed to-day concerning Julien Bethenod's invention of a sparkless wireless. He said that the wireless sparks undoubtedly slackened the speed of transmission by the interruption of the current. With a continuous current the speed would be greatly enhanced.
    If Bethenod could obtain, as he asserted, 20,000 oscillations a second, said Branly, it would make wireless telephony a realizable proposition for long-distance conversation.
    Branly says that he knows Bethenod as a serious scientist, who is Chief Engineer of the Société Radiotelegraphique, but he is not acquainted with his scientific achievements. He doubts whether the new invention would permit the operation of wireless stations in close proximity without any confusion in the messages transmitted.
