Mobile Phone Call: #OnThisDay

On the 3rd of April 1973 the first mobile phone call was made in downtown Manhattan, NYC by Motorola employee Martin Cooper to the Bell Labs headquarters in New Jersey.

 Martin Cooper, was a Motorola researcher and executive and called Dr. Joel S. Engel of Bell Labs, his rival.

The prototype handheld phone used by Dr. Cooper weighed 2 kilograms (4.4 lb) and measured 23 by 13 by 4.5 centimetres (9.1 by 5.1 by 1.8 in). The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.
