(1973-)Thanks to his development in 1973 for the cellular pleasure we are enjoying today.


Jesus of Cell Phone

Computer has an attribution to  Jesus (Dennis Ritchie and Bill Gates), so does cell phone just with a different name on the same title. So, there is a question: Who is this Jesus of cell phone, who invented it ? The cell phones and smart phones that you are using today are the grandchildren of the this creator's invention. 



Who is the "Jesus" of mobile phone? (Tips: Refer to introduction part or the image below)





















































Dr. Martin Cooper in cellular phone development

Dr. Martin Cooper(born December 26, 1928 in Chicago, Illinois, USA) is an American former Vice President of Motorola and General Manager of systems division in the 1970s. Cooper served in the Navy before during WWII period, after the war ended, he left the navy and took a job at Teletype Communication and continue pursing his studies in University. In 1950, he pursued Bachelor's degree of Electrical Engineering at Illinois Institute of Technology. In 1954, after completing the degree, he was hired by Motorola, the place that directed him towards world's biggest invention later and went on to earn a Master's from IIT in 1957. After 13 years of journey in Motorola, Cooper was put to be in charge of its car phone division where he started leading Motorola's cellular research. Cooper foreseen the prospect of mobile phone not only viable in a car, but also able to be a small, light enough and portable device. Thanks to years of research and development in portable products directed by Cooper and new technologies from all over the company, when the pressure was on, it took only 90 days in 1973 to create the first portable cellular 800 MHz phone prototype.


First cellular call in the world made by Martin Cooper


Cooper's famous quote:


"People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are, unfettered by the infamous copper wire. It is that freedom we sought to vividly demonstrate in 1973."

Martin Cooperadded, "As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life."

In 1973, when the company installed the base station to handle the first public demonstration of a phone call over the cellular network, Motorola was trying to persuade the Federal Communications Commission to allocate frequency space to private companies for use in the emerging technology of cellular communications. After some preliminary testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public.

On April 3, 1973, standing on a street near the Manhattan Hilton, Mr. Cooper decided to attempt a private call before going to a press conference upstairs in the hotel. He picked up the 2-pound Motorola handset called the Dyna-Tac and pushed the "off hook" button. The phone call came alive, connecting Mr. Cooper with the base station on the roof of the Burlington Consolidated Tower (now the Alliance Capital Building) and into the land-line system. To the bewilderment of some passers-by, he dialed the number and held the phone to his ear.

Following the 1973, public demonstration, using a brick-like 30-ounce phone, Cooper started the 10-year process of bringing the portable cell phone to market. Motorola introduced the 16-ounce "DynaTAC" phone into commercial service in 1983, with each phone costing the consumer $3,500. It took seven additional years before there were a million subscribers in the United States. Today, there are more cellular subscribers than wireline phone subscribers in the world, with mobile phones weighing as little as 3 ounces.
