Dr. Martin Cooper

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first portable handset and the first person to make a call on a portable cell phone in April 1973. The first call he made was to his rival, Joel Engel, Bell Labs head of research.
AT&T's research arm, Bell Laboratories, introduced the idea of cellular communications in 1947. But Motorola and Bell Labs in the sixties and early seventies were in a race to incorporate the technology into portable devices.
Cooper, now 70, wanted people to be able to carry their phones with them anywhere.
While he was a project manager at Motorola in 1973, Cooper set up a base station in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public.
