Martin Cooper, the father of the cell phone, with the first cell phone he used 30 years ago
The first mobile telephone call was made on April 3, 1973 by Martin Cooper, a former Motorola inventor, who is known as "the father of the cellphone".
From Sixth Avenue in New York he rang the boss of a rival manufacturer who was less than thrilled to discover that he had lost the race to develop a portable, hand–held device. Cooper later recalled: "There was silence at the other end of the line. I suspect he was grinding his teeth."
The weight of the phone used to make that call was about the same as a bag of sugar (2lb). The brick–like battery required, which allowed a talk time of just 30 minutes and took 10 hours to charge, made carting it around even more of a chore.

The phones are still highly sought after on the second–hand market and sales boomed after a false rumour that a software glitch allowed fraudulent bank transactions to be carried out using the device.
Mobile phone texting was first introduced 21 years ago. Neil Papworth, a 22–year–old software programmer from Reading, sent the first message when he wished his friend Richard Jarvis of Vodafone: "Merry Christmas." At the time mobile phones didn't have keyboards so it was sent via personal computer.
