Dr. Martin Cooper is the person credited with both inventing the modern cell phone as well as making the first cell phone call in New York City, New York in April 1973. A related invention is the cave radio phone invented by Nathan Stubblefield who was awarded a patent for the idea in the early 20th Century (1908).
The Cell Phone: Marty Cooper's Big Idea. Editor's note: Though Martin Cooper and his team at Motorola built and demonstrated the first cell phone, there were many fathers of the technology involved in transmitting calls. Prominent among them: Amos Joel, Jr. of AT&T/Bell Labs, who created the system that switches signals from one cell tower to another - the basic component that lets callers talk while moving.
