Seth Henry Neddermeyer (September 16, 1907 – January 29, 1988) was an American physicist who co-discovered the muon, and later championed the implosion-type nuclear weapon while working on the Manhattan Project at the Los Alamos Laboratory during World War II.
Neddermeyer was recruited to work on the Manhattan Project by J. Robert Oppenheimer from the National Bureau of Standards. He proposed using an implosion method for the bomb that would use powerful explosives to compress a core of radioactive plutonium to a critical mass.
Nov 16, 2021 · We highlight Seth H. Neddermeyer, George B. Kistiakowsky, John von Neumann, Luis W. Alvarez, and James L. Tuck as key personnel who led the conceptual design and implantation of HE and implosion research at Los Alamos.
Espionage and the Manhattan Project, 1940-1945. Because the gun-type bomb design seemed so simple and practical, Deke Parsons had assigned implosion studies a low priority and placed the emphasis on the more familiar artillery method. Consequently, Seth H. Neddermeyer performed his early implosion tests in relative obscurity.
The lab supported a small implosion program under Seth H. Neddermeyer even as Ordnance Division head William S. Parsons, an experienced gunnery officer, maintained that implosion would never be reliable enough for field use.
Atomic Rivals and the ALSOS Mission, 1938-1945. Espionage and the Manhattan Project, 1940-1945. The final link in the Manhattan Project's far-flung network was the bomb research and development laboratory at Los Alamos, located in the mountains of northern New Mexico.
