Born in Jackson, Mississippi in 1934, Dr. Henry Sampson is a prolific inventor and pioneer in the field of nuclear engineering. On July 6. 1971 he was awarded a patent, with George H. Miley for a gamma-electrical cell, which is a device that produces a high voltage from radiation sources, primarily gamma radiation.
On April 3, 1973, using the patented technology they created, Motorola engineer Marty Cooper placed the first call from a cell phone. Becuase of Sampson’s Invention and patent of the gamma-electrical cell, portable cell phones were possible. Other accomplishments for Sampson include becoming the first African American in the united states to earn a Ph.D. in nuclear engineering.
