With a Motorola DynaTAC 8000x which weighed only 800 grams was the world’s first phone call from a mobile phone made forty years ago.
The third april 1973, then an engineer at Motorola Marty Cooper made the first public phone call from a mobile phone. The call was made to the leader of the rival Development Department at Bell Labs to deliver the news that Motorola had won the race to make the first cell phone.
The phone was called DynaTAC 8000x and weighed just around 800 grams, well more than the 100 gram as most phones today and messing around.
Although several mobile phones the size of suitcases had seen the light of day, is regarded as the first true 8000x DynaTAC cell phone as the “only” weighed 800 grams, was 25 centimeters high and therefore could be used as a handheld device.
An old promotional video for DynaTAC can be seen here.
In addition, The Verge last year created an excellent interview with Marty Cooper where they, among other things, chatting about Motorola’s future, today’s technological advances and what the head of Bell Labs said to receive the fabled calls. The interview can be read here.
