					Martin Cooper - Inventor Of The Cellphone

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.

The First Cellphone (1973)

Name: Motorola Dyna-Tac
Size: 9 x 5 x 1.75 inches
Weight: 2.5 pounds
Display: None
Number of Circuit Boards: 30
Talk time: 35 minutes
Recharge Time: 10 hours
Features: Talk, listen, dial
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 initial 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 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.

Who is he?

Cooper grew up in Chicago and earned a degree in electrical
engineering at the Illinois Institute of Technology. After four
years in the navy serving on destroyers and a submarine, he
worked for a year at a telecommunications company.

Hired by Motorola in 1954, Mr. Cooper worked on developing
portable products, including the first portable handheld police
radios, made for the Chicago police department in 1967. He then
led Motorola's cellular research.
