Transcript of The History of the Telephone
* Alexander Graham Bell was credited for the first telephone in 1876. He also had an assistant, Thomas Watson. The name, telephone, is Greek and it means far and sound. The invention of the telephone allows people to hear people talk from very far away. Also the telephone is a way to talk to someone who you may not be around at the moment. When you need to talk to someone who is not around you is when the telephone comes in handy. Life without the invention of the telephone may be harder than some people may think. Without the telephone you would have to be in the same place as the person your talking to so that they can hear you. If people are in different states they can't communicate with others without a telephone. You wouldn't be able to hear the voices of those far away and you wouldn't be able to communicate without it.
