Telephones
Over 100 years ago a great man by the name Alexander Graham Bell created telephones. Which has become a great accomplishment and still to this day is very user friendly to billions of peoples all over the world.
In the year of 1870, two inventors Elisha Gray and Alexander Graham Bell both independently designed devices that could transmit speech electrically (Telephones).
Both men rushed their respective designs to the patent office within hours of one another. Alexander Graham Bell presented his telephone first. Elisha Gray and Mr. Graham Bell entered into a famous legal battle over the invention, which Bell won.
The telegraph and telephone are both wire-based electrical systems. Alexander Graham Bell success with the telephone came as a direct result of his attempt to improve the telegraph.
When Mr. Bell begun experimenting with electrical signals, the telegraph had been an established means of communication for nearly 30 years. Although a highly successful system, the telegraph, with its dot and dash Morse code, was basically limited to receiving and sending one message at a time. Bell’s extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. The idea of a multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. His “harmonic telegraph” was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.
On June 2, 1875, Alexander Graham Bell while experimenting with his technique called “harmonic telegraph” discovered he could hear a sound over a wire. The sound was that of a twanging clock spring. Bell’s greatest success was achieved on March 10, 1876, marked not only the birth of the telephone but the
