AFRICANGLOBE - Although many people are not aware of it, Henry T. Sampson is an African American inventor, best known for creating the world's very first cell phone. "On July 6, 1971, he was awarded a patent, with George H. Miley, for a gamma-electrical cell, a device that produces a high voltage from radiation sources, primarily gamma radiation, with proposed goals of generating auxiliary power from the shielding of a nuclear reactor." On April 3, 1973, using the patented technology they created, Motorola engineer Marty Cooper placed the first public call from a cell phone, a real handheld portable cell phone.
