Harrison BrownDied 8 Dec 1986 at age 69 (born 26 Sep 1917).Harrison (Scott) Brown was an American geochemist known for his role in isolating plutonium for its use in the first atomic bombs and for his studies regarding meteorites and the Earth's origin. He was one of 67 concerned Manhattan Project scientists at Oak Ridge to sign a July 1945 petition to the President, which said, in part, "...Therefore we recommend that before this weapon be used without restriction in the present conflict, its powers should be adequately described and demonstrated, and the Japanese nation should be given the opportunity to consider the consequences of further refusal to surrender." His later studies included mass spectroscopy, thermal diffusion, fluorine and plutonium chemistry, geochemistry and planetary structure. |
