Martin Cooper

• Martin Cooper invented the cell phone in 1947. He
  thought of making the cell phone when he wondered
  how people made the car phone. He then wanted to
  make a phone that would be able to go with people
  wherever they go. He then studied how they made
  the car phone. The car phones were phones in some
  cars that worked only when they were a certain
  distance away from the service area.

How it is used today

• This invention is helping our lives today because
  if something would happen to you or a family
  member, you would have no way to tell other
  people until they got home. Today a lot of kids
  have cell phones because when they are at school
  and they need a ride home after a sport. They can
  use their phone, and not pay to use a pay phone.
  They would still need to pay for the phone bill,
  but if they are in the service area they wont
  need to pay.
