A Big Indispensable Invention.

You know what a telephone is. We use it every day but whats behind it? well here is the part of the history where our friend Alexander Graham bell appears.

                                                                      Alexander Graham Bell was from Scotland.

His father and his grandfather were speech therapists (cience that studies disorders of language and hearing). Eventually he decided to dedicate his life to speech therapist. When he was 21 years old he started to work for his dad on london before he moved to america. 

Bell was really interested on improving the education for deaf people. when he was 26 he stared to desingn a machine that could imitate the human voice and reproduct vowels and consonants for deaf people to communicate. The result of the project was the telephone in 1876.

He opened the first phone center in New Haven, Connectus, U.S. and 6 years later the first long distance call was made in Boston, New York and Massachusetts.

Alexander Graham Bell died when he was 75 years old. He died without knowing that what he was leaving here was going to be something indispensable for the whole world.
