Martin Cooper (inventor) - Wikipedia
On April 3, 1973, Cooper placed the first public call from a handheld portable cell phone while working at Motorola, from a Manhattan sidewalk to his counterpart at competitor Bell Labs. Cooper reprised the first handheld cellular mobile phone (distinct from the car phone) in 1973 and led the team that redeveloped it and brought it to market in 1983. He is considered the "father of the (handheld) cell phone", and received the 2015 IEEE Masaru Ibuka Consumer Electronics Award for this work.
