Cell phone turns 40
On April 3, 1973, Marty Cooper, a Motorola engineer, made the first public call from a cell phone. From Manhattan, Cooper called his main competitor, Joel Engel, head of research at Bell Labs: “Joel, this is Marty. I’m calling you from a cell phone, from a real portable cell phone. ”
The call was made from a prototype Motorola DynaTAC 8000x, which weighed about 1 kilogram. The first sales of it began only 10 years later - in 1983.
Years later, Richard Frenkel, head of systems development at Bell Laboratories, said about DynaTAC: “It was a real triumph. At that time, we used 14-kilogram telephones in the cars. Their ability to hold everything needed in 1 kg was a big breakthrough. ”
