Harrison Brown

Harrison S. Brown is a nuclear chemist and geochemist who worked on ways to separate plutonium from uranium at the Manhattan Project’s Metallurgical Laboratory during the war.  

The techniques he helped develop were used at the Hanford Site to produce the plutonium used in the Fat Man bomb dropped on Nagasaki. He has since lectured on the dangers of nuclear weapons, and wrote on the issues involving arms limitation, natural resources, and world hunger.
