The first cellphone was invented fifty years ago. The man who built that phone, Martin Cooper, is now 94 years old. He has been called the "father of the cellphone".
In the early 1970s, Cooper worked for American technology company Motorola. At the time, Motorola and other companies were competing(竞争) to create cellphones. Cooper made the first public call with a handheld telephone in New York City on April 3, 1973. The device(设备), called Dyna -TAC, weighed about 1 kilogram and was 28 centimeters long.
He developed the phone with his team at Motorola for over five months. They could only talk on it for about 25 minutes. Cooper noted that such a call time was not a problem, because this phone was so heavy that you couldn't hold it up for 25 minutes. Cooper said, "The only thing that I was worried about: 'Is this thing going to work?' And it did. At the time, we had no way of knowing this was an important moment in history."
Today, the phone allows us to do many things. Cooper said the progress of cellphones is sure to continue long into the future. He thinks future phones will monitor our health at all times and batteries(电池) could even be replaced by human energy . He believes that one day, our phones might be small devices inside our ears.
Cooper has also expressed his worry. "We don't have any privacy(隐私) anymore because everything is now recorded someplace," Cooper said. However, he said hopefully that cellphones will continue to develop in ways that can greatly help humans.
