THE TELEPHONE

The telephone is a much younger invention than the telegraph. Fifty telegraph companies had already been operating in the United States alone, when the French mechanic Charles Boursel first suggested the idea of transmitting speech electrically. The first who put his idea into practice was the German Philipp Reis, but his telephone was too primitive to find any practical application. A telephone that found the application was invented by the American Graham Bell. On March 10, 1876, he made an instrument that successfully transmitted a sentence. To his assistant who was in another room, Bell transmitted the message, "Mr. Watson, please come into my room."

Bell's telephone was very simple. It consisted of a metal diaphragm placed in the field of a horseshoe magnet. The diaphragm, vibrating under the impact of sound waves, produced oscillations in the electric current transmitted along the wires. A similar device at the other end of the line turned the electric oscillations into sound.

The telegraph and the telephone were considered to be the "final" solution to the communication problem. But they were soon followed by an even more wonderful invention, which made communication possible without wires. It was the radio.
