In Munich

In Munich, a performance of Richard Wagner's Walku"re has been broadcast --but not by radio. Subscribers only "listened in." Their regular telephones had been hooked up to the transmitting microphones in the National Theatre through the central exchange. An invention devised by one Dr. Steidle was responsible for the feat. This provided for automatic interruption of a subscriber's music whenever a regular telephone call demanded his attention. Inasmuch as the reproduction was free from the "static" disturbances common to wireless communication, it was found more satisfactory, as well as more exclusive, than radio-music. The experiment was conducted by the Bavarian Federal Ministry of Posts, Telegraphs and Telephones.
