Henry T. Sampson (1934 -2015) – Gamma-electric cell
Henry T. Sampson became the first African American to earn a Ph.D. in nuclear engineering in the United States. In 1963, he was awarded a patent for a gamma-electric cell, which converts radiation into electricity. The device is used for capturing the radiation in the shielding of a nuclear reactor and transforming it into auxiliary power. This technology is used to generate additional power in nuclear reactors. Sampson’s invention has been significant for the nuclear power industry and has contributed to developing innovative power sources.
