Alexander Graham Bell Story
Alexander Graham Bell was born in March 1847 and died in August 1922. He receive most of his education from his mother who was an unusually gifted painter and pianist, despite her deafness.
In 1870, after the death of two of his brothers, the Bell family moved to Canada for the sake of his health. Expanding on his father’s work of teaching deaf people to communicate, he began working on transmitting telephonic messages.
While pursuing his teaching profession, he conducted his research to perfect the harmonic telegraph, so as to transmit several telegraph messages simultaneously over a single wire. Alongside, he was also drawn towards another idea of transmitting the human voice over a single wire.
On march 10, 1876, he produced the first intelligible telephone call, when he summoned his assistant, with words that Bell transcribed in his lab notes as “Mr. Watson-come here-i want see you”. Watson heard his voice through the wire and thus received the first telephone call.
