Only two hours later a similar request made another American named Grey. This happens with the inventors and to this day, albeit very infrequently. Good luck Bella was still in the fact that to do an outstanding invention helped him to an accident. Yet a much greater extent by their appearance phone obliged huge efforts, persistence and knowledge of this man. Handset Bell served in the queue for transmission and reception human speech and the phone did not ring Bell.

In 1876, Alexander Graham Bell demonstrated his machine at the Philadelphia World’s Fair.
