• Biografiak

Scottish inventor and researcher was born in Edinburgh in 1847. Since he was very young he worried about the transmission of the sound, since in his family there were many companions who had worked on the investigation of these problems. Bell's father was the first to teach the born deaf to speak.

Between 1868 and 1870 he worked with his father in the study of the transmission of words and in dialogue with the deaf children of Edinburgh. At that time TB hit the whole of Scotland hard and brought two Bell brothers. When Alexander became ill, the family decided to go to Canada. Fully trained, Bell completed a year there and in 1873 he settled in the city of Boston of the USA, where he was professor of the University. He deepened his knowledge of the mute language at the University. Bell's research on sound dynamics is from this time.

Bell believes that sound waves could become codiffuse and desicodiffuse electrical impulses. Bell insisted that remote communication would be achieved. In his own house he built the necessary circuit to confirm this theory. On the ground floor he located the apparatus that emitted the sound waves in this hypothetical communication system and on the upper floor the receiver that would receive them.

One morning he worked down, he emptied a bottle of acid on top. Overwhelmed, he called his assistant. His assistant, Watson, later explained, suffered a terrible bewilderment when suddenly the upper floor apparatus began to speak. Therefore, Bell worked correctly and despite being dissatisfied, the result of this accident was the first telephone conversation.

In 1876 he patented his invention. That same year the anniversary of US independence was celebrated in Philadelphia and Bell was the main protagonist of the events. The phone had immediate access to the US. and at age 30 Bell was a great inventor.

Bell continued to work on improving his invention and the language of the deaf-mutes. In 1881 he invented the apparatus that detected metal and in 1883 he created the journal Science. In 1915 the first telephone network that crossed the US was inaugurated. Bell and Watson were the first users of the new network. In addition to the plants in the same house, Bell was able to demonstrate that the two coasts of the same continent could be united.

Alexander Graham Bell died on August 2, 1922 in the Canadian city of Baddeck.
