The telephone: a little object, a big invention.

The telephone was created in 1874 by Alexander Graham Bell, this telephone was constituted by a transmitter and a receiver.This telephone works but it have a very weak signal. The creation of the telephone involves other inventors like: Antonio Meucci, Philip Reis, and Elisha Gray.

Important dates in the telephone history:

1831.- Michael Faraday show that the vibrations on metal objects couldbe transformated to electrical signals.

1861.-Philip Reis was the first inventor who constructed a machine that could change sounds to electrical signals.

1874.-Alexander Graham Bell had the idea for a telephone while woking on telegraph machines.

1877.-The Bell telephone company was created and the first telephone exchange was developed in Connecticut.

1879.-The first telephone exchange was constructed in London, England.

1888.-William Gray create the first pay telephone.

My opinion:

I think that the telephone is the most important invent in the communications history, it's something that
we use today still. I think that his versatility has made it a revolutionary invent.
