History of telephone

The early history.

Alexander Graham Bell is considered the inventor of the telephone. He was trying to improve the telegraph which was used to send and receive massages using an electrical system At the time, they were not able to send and receive more than one message at the same time. With the help of Bell’s knowledge of music he found a way to make the telegraph send and receive more than one message at the same time.

On March 10th 1876 the telephone was discovered and this marked the end of telegraph use (Mary Bellis. 2012). The first sound was transferred by Alexander to his assistant Tomas A Watson, while they were working on the experiment.

In 1831 Michael Faraday discovered that vibrations of metals can be converted in to electrical waves (N.P.2006). The telephone converts the human voice to electrical waves that are transfered through a wire and then back to human voice again. This was the basic principle of the telephone.

The telephone began to spread and was used by human in 1877 (Mary Bells. 2012). The switch board of the telephone was invented by Leroy Firman and he got his first patent of it in this year also.  This was the beginning of modern telephonic development.
