Louis Alexander Slotin (/ ˈ s l oʊ t ɪ n / SLOHT-in; [1] 1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who took part in the Manhattan Project.Born and raised in the North End of Winnipeg, Manitoba, Slotin earned both his Bachelor of Science and Master of Science degrees from the University of Manitoba, before obtaining his doctorate in physical chemistry at King's ...
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
Louis Slotin, a colleague of Daghlian's, was killed in 1946 while performing criticality tests on the same plutonium core. [6] After these two incidents it became known as the "demon core", [11] and all similar criticality experiments were halted until remote-controlled assembly devices were more fully developed and available.

Part of the character is loosely based on the scientist Louis Slotin. [3] Contrary to Merriman's death in the movie, Slotin's accident and death occurred after the dropping of the two bombs on Japan, and his early death was feared by some as karma after the event. [ 4 ]
Louis Slotin. Dr. Louis Slotin, a physicist at the Los Alamos research center, was fatally injured during an experiment with a "subcritical nuclear assembly", a plutonium core and two halves of a beryllium sphere. The purpose was to measure the increase in radiation as the two hemispheres (which deflected neutrons back into the plutonium) were ...
Alvin Cushman Graves was born on November 4, 1909, in Washington, D.C., the youngest of six children.He was the son of Herbert C. Graves, an engineer with the United States Coast and Geodetic Survey and member of the American Commission to Negotiate Peace after World War I.
Louis Slotin: 30 May 1946: The 35-year-old Canadian physicist and Manhattan Project scientist died as the result of an accident while performing an experiment called "tickling the dragon's tail" with a plutonium core which came to be known as the "demon core". His screwdriver slipped, exposing him to a fatal dose of radiation.
This incident in which "Cochran" receives a fatal dose of radiation while assembling the Hiroshima bomb is a highly fictionalized reference to the deaths of Harry Daghlian and Louis Slotin, members of the Manhattan Project who died after contact with radioactive material on 21 August 1945 and 21 May 1946.
