The invention of telephone

In early days of Western Science, Frances Bacon in his book New Utopia published in 1627 described a telephone-like device involving a long speaking tube.

Slightly later, in 1667, Robert Hooke, performed experiments involving the transmission of sound along a taut string.

In the 1850s in France, Belgian-born inventor Charles Bourseul presented a report to the Academie Des Sciences, which discussed the possibility of transmitting sound vibrations via electricity.

On March 7, 1876 the US Patent Office issued to a young man named Alexander Graham Bell what has since been described as the most valuable patent ever issued.

Details of Bell’s telephone which is called ‘receiver’ as described in his patent, indicated that a telephone consisted of two receivers, used alternately for speaking and hearing; receivers were connected by a wire line.

‘Mr. Watson, come here. I want to see you.’ Alexander Graham Bell said these words to Thomas Watson on March 10, 1876. Bell and Watson were in different rooms at that time.

Bell managed to complete a working model of his telephone and exhibited it to various dignitaries, including Emperor Dom Pedro of Brazil at Philadelphia exposition.

The French government later gave Bell a prize of 50,000 francs for inventing the telephone. Alexandra turned the money over a laboratory for research into aids for the deaf.
