Cooper conceived of the portable cellular phone and led the team at Motorola that created the first phone in 1973. He made the first public cell phone call on April 3,1973. He contributed to the technology of the wireless communications industry for over 60 years and contributed to every significant advancement in wireless communications, during this time.
