Harris Louis Mayer (February 15, 1921 – September 17, 2023) was an American physicist known for his work on the Manhattan Project and Project Orion, focusing on phenomena related to opacity in the context of nuclear radiation. Mayer notably calculated radiative transfer opacities critical for thermonuclear bomb efficiency. His contributions earned him a PhD post-declassification of his wartime work. Later, he engaged in space propulsion studies involving tethers. He provided insights for the documentary ‘To Mars by A-Bomb: The Secret History of Project Orion’ before passing away at the age of 102.
