The telephone






          Long before the telephone was invented, people knew that sound could travel
          along a wire—children could do it with two tin cans and some string. In the

          second half of the 20th century, many individuals searched for a better way
          to transmit speech. The Scotsman Alexander Bell made a breakthrough in 1876

          by converting sound into an electric current that could be sent along wires.

           In 1876, scientist Alexander Graham Bell,
           working on the invention of the telephone
           in the US, became the first person to
           receive a patent for it. An astute business
           sense and flair for promotion kept him
           ahead of his rivals.

              the telephone so much
            that she wanted to buy it.
