The first mobile telephone call was made on 17 June 1946 from a car in St. Louis, Missouri, USA, using the Bell System’s Mobile Telephone Service.[9] This was followed in 1956 by the world’s first partly automatic car phone system, Mobile System A (MTA) in Sweden. The MTA phones were composed of vacuum tubes and relays, and had a weight of 88.2 pounds (40 kg)
John F. Mitchell, Motorola’s chief of portable communication products in 1973, played a key role in advancing the development of handheld mobile telephone equipment. Mitchell successfully pushed Motorola to develop wireless communication products that would be small enough to use anywhere and participated in the design of the cellular phone.[12][13] Martin Cooper, a Motorola researcher and executive, was the key researcher on Mitchell’s team that developed the first hand-held mobile telephone for use on a cellular network.[14] Using a somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on April 3, 1973 to his rival, Dr. Joel S. Engel of Bell Labs.[15][16]
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 or 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.
