gamma electric cell

Henry T. Sampson’s patent for the gamma-electric cell, which converted nuclear radiation into electricity without the need for a heat cycle, 1971. While sometimes erroneously credited as an early cellphone (the two technologies are unrelated), the gamma-electric cell is used in reactor instrumentation. Samson was the first African-American to be awarded a Ph.D. for nuclear engineering in the United States, and has produced several documentaries on early African-American filmmakers.
