But that was not the case in 1973 when Martin Cooper made his first cellular phone call from a New York City street and New Yorkers stared gaping at him. But the history of cell phone starts further back in time.

In 1865 a dentist, Dr. Mahlon Loomis was the first person to communicate through wireless via the atmosphere. He came up with the idea of transmitting and receiving messages using the atmosphere as a conductor and sending up kites covered with copper screens that were linked to the ground with copper wires. Loomis was awarded a $50,000 research grant by congress.

But let us move forward to the twentieth century and the invention of the cell or wireless phone as we know it today. This brings us to a man often referred to as the father of the cell phone, Martin Cooper. He was employed by Motorola and worked on developing the first hand held radios made for the Chicago police department in 1967. He then went on to lead Motorola’s cellular research.  Read more...
