Motorola engineer Martin Cooper from Sixth Avenue in New York took the first handset mobile phone call on April 3, 1973, while walking from 53rd to 54th Streets. Cooper put a prototype of 2 1/2 pounds in his ear, calling a rival at the AT&T Joel Engel from Bell Laboratories to proclaim that his team at Motorola had designed a mobile telephone. According to the Wired magazine, the bulky “shoe,” almost as large as a shoebox, allowed users to converse for 35 minutes and required ten hours to recharge.

It spent ten years resolving technological and regulatory barriers.  The early phones were too large and costly for most users, but they set a pattern for the sleek, lightweight devices that are now standard equipment for almost anyone.’
