Biography - A Short Wiki
Winner of the 1951 Nobel Prize in Chemistry for his discovery of plutonium and transuranium, which is heavier than uranium. He was also the Chairman of the United States Atomic Energy Commission from 1961 to 1971.
He was born in Ishpeming, Michigan, the son of a Swedish immigrant mother, who he later saved with one of his discoveries.
Dr. Seaborg, who was 86, died of complications of a stroke he suffered last August while exercising on a flight of stairs at a scientific meeting in Boston. His longtime collaborator and friend at the Lawrence Berkeley National Laboratory in California, Albert Ghiorso, said that after Dr. Seaborg collapsed, he fell down the stairs and was seriously injured and lying helpless for several hours until he was discovered. He was mostly paralyzed thereafter.
