Today, most of us have telephones in our homes. One hundred and twenty years ago ,people were not so lucky. Alexander Graham Bell invented the telephone.

Bell improved the way telegraph Messages could be sent down one wire at time. Bell experimented some more and invented a microphone that could send sounds down a wire .
