Martin Cooper invented the cell (mobile) phone. He was the first one to make a call and speak on his moble phone.
Mr Cooper, born December 26, 1928, 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.
