Who invented the telephone
Long said that who invented the telephone was the scientist and Scottish-born American inventor Alexander Graham Bell, along with Elisha Gray, but Bell was not who I think the phone, only registered the first patent in the year of 1876. Gray recorded the second patent.
In June 2002 the United States Congress resolution 269 decreed that Antonio Meucci was who invented the phone, that I called it teletrofono. Economic problems only Meucci could briefly describe his invention but not patented it.
Brief history of the invention of the telephone:
Description of the what is phone: is a telecommunications device designed to transmit by means of electric signals (beeps) distance.
In the year of 1857 Antonio Meucci built and installed a rudimentary telephone to connect your office in the basement of his home in Staten Island with the bedroom on the second floor, because his wife could not navigate the House that suffered from rheumatism. But not having enough money he could not patent his invention. Meucci took his invention of the telephone to the Western Union company but they paid no attention and stayed with the materials, it is not proven but it is said that these materials fell in the hands of Alexander Graham Bell, who use them to create your phone.
Then in 1876 Bell discovered that to transmit the human voice should be a continuous current, then built and patented the first phone capable of transmitting and receiving quality human voice. Bell patent only occurred a few hours before the Elisha Gray.
Another important person was Thomas Alva Edison who incorporated him notable improvements to the phone, as the microphone of granules of carbon which increased its broadcast power.
Antonio Meucci was recognized as the inventor of the telephone in the year of 2002 by the Congress of the United States. Bell patent was questionable from the beginning since according to said Bell had someone who helped him in the Patent Office and warned him with time that would compare two Gray’s and Bell’s patents to discard the worst and the most expensive. Bell was able thanks to his friend compare patents and added a note to hand where he described an alternative design just like the Gray to the patent of it.
