simple history about the telephone!
While Alexander Graham Bell was experimenting with telegraph instruments in the early 1870s, he realized it might be possible to transmit the human voice over a wire by using electricity.
Bell's interest in electricity continued and he attempted to send several telegraph messages over a single wire at one time. Lacking the time and skill to make the equipment for these experiments he enlisted the help of Thomas A. Watson from a nearby electrical shop. The two became fast friends and worked together on the tedious experimentation to produce sounds over the "harmonic telegraph." It was on June 2, 1875, while Bell was at one end of the line and Watson worked on the reeds of the telegraph in another room that he heard the sound of a plucked reed coming to him over the wire.
The next day, after much tinkering, the instrument transmitted the sound of Bell's voice to Watson! wow! The instrument transmitted recognizable voice sound, not words. Bell and Watson experimented all summer and in September, 1875, Bell began to write the specifications for his first telephone invention. By March 1876 he managed to make a transmission, but the sound was very faint. The invention was published on March 7, 1876.
