  • The first cellphone was invented fifty years ago this week.
  • 2
  • The man who built that phone, Martin Cooper, is now 94 years old.
  • 3
  • Cooper, who has been called the "father of the cellphone," has been speaking with the media as he looks back at his efforts to create a device that greatly changed our world.
  • 4
  • In the early 1970s, Coper worked for American technology company Motorola.
  • 5
  • At the time, Motorola and other manufacturers were attempting to create wireless phones that could work in vehicles and also be carried.
  • 6
  • There was intense competition between Motorola, Bell Labs and AT&T to build the first truly portable phone.
  • 7
  • The technology used to create the first cellphone is known as cellular.
  • 8
  • This technology uses many small, interconnected transmitters that give off wireless signals and connect cellphones to the internet.
  • 9
  • Cooper made the first public call from a handheld portable telephone in New York City on April 3, 1973.
  • 10
  • The device, called Dyna-TAC, weighed about 1 kilogram and was 28 centimeters long.
  • 11
  • He developed the phone with his team at Motorola over a period of five months.
  • 12
  • The first model permitted about 25 minutes of talk time.
  • 13
  • Cooper noted that such a talk time was not a problem, since "This phone was so heavy, you couldn't hold it up for 25 minutes."
  • 14
  • Speaking about that moment to The Associated Press, Cooper said, "The only thing that I was worried about: 'Is this thing going to work?' And it did."
  • 15
  • Cooper admitted that at the time, "We had no way of knowing this was a historic moment."
  • 16
  • While Cooper is pleased that his invention has opened up a series of technological possibilities for cellphone users, he thinks many people are just too obsessed with their devices.
  • 17
  • "I am devastated when I see somebody crossing the street and looking at their cellphone.
  • 18
  • They are out of their minds," Cooper told the AP.
  • 19
  • "But after a few people get run over by cars, they'll figure it out," he joked.
  • 20
  • Today, Cooper uses a late model iPhone.
  • 21
  • He likes that the phone permits him to do numerous things, such as read emails, watch YouTube and control his hearing aid devices.
  • 22
  • But mostly, he says he uses the phone just to talk to people.
  • 23
  • Cooper said the modern progress of cellphones is sure to continue long into the future.
  • 24
  • He predicts phones will develop to the point of being able to be "distributed on your body," with sensors "measuring your health at all times."
  • 25
  • Cooper said batteries could even be replaced by human energy.
  • 26
  • "You ingest food, you create energy. Why not have this receiver for your ear embedded under your skin, powered by your body?" he imagined.
  • 27
  • But the cellphone inventor has also expressed worries about how the device has created serious risks for users, especially in the area of privacy.
  • 28
  • "My most negative opinion is we don't have any privacy anymore because everything about us is now recorded someplace," Cooper said.
  • 29
  • But, he noted he is hopeful that cellphones will continue to progress in ways that can greatly help humanity.
  • 30
  • "Each generation is going to be smarter...They will learn how to use the cellphone more effectively," Cooper said.
  • 31
  • "Humans sooner or later figure it out."
