Dr. Martin Cooper, one of the inventors of the first cell phone
NEW YORK (AP) — A cell phone was first used exactly 40 years ago.
On April 3, 1973, the first handheld portable phone was demonstrated
for reporters by Motorola executive Martin Cooper (pictured) on a New
York City street corner.
Cooper contacted Joel S. Engel, of Bell Labs, using a Motorola device
that looked like "a small, domesticated version of military walkie-talkies,"
according to an Associated Press report at the time.
The device weighed just under three pounds. The iPhone 5 weighs just
under 4 ounces.
