Celluar phone, who is the brains behind the call? Dr. Martin Cooper was raised in Chicago and earned his degree as an electrical engineer from Illinois Institute of Technology. He spent four years in the navy working on a submarine and destroyers. He then worked in Telecommunications Company for one year. With this change of scenery he was hired in 1954 by Motorola. Dr. Cooper was one of the people responsible for the first portable police radios in 1967 in the Chicago police department. After this successful venture Dr. Cooper was promoted to lead Motorola’s cellular research as the project manager.
The idea of the cellular communications was introduced by Bell Laboratories, the research arm of AT&T, in 1947. It was in the 60’s and early 70’s however that Bell Labs and Motorola raced to see who could incorporate the technology to the portable devices. At the age of 70 Cooper’s desire was to enable persons to have the luxury of walking with their phones anywhere they wished to go.
Needless to say, Motorola won the race for cellular phones and Cooper is now considered to be the inventor of the first portable handset as well as the first one to successfully make a call on the handset in April, 1973. Guess who he made the first call to? Yes, he made it to his rival, Joel Engel, the head of the research department at Bell Labs.
In 1973, a base station was set up in New York with the first 2-pound, Dyna-Tac Motorola handset. After doing some initial testing, the Federal Communications Commission (F.C.C.), Motorola and Mr. Cooper they were ready to publicly display the cellular phone.
