Discovered & investigated 10 elements in the Periodic Table, inc. Seaborgium, named for him; shared 1951 Nobel Prize in Chemistry


Type: Signed card
Description: (1912-1999)  American chemist, his involvement in the synthesis, discovery and investigation of 10 transuranium elements earned him a share of the 1951 Nobel Prize in Chemistry. His work in this area also led to his development of the actinide concept and the arrangement of the actinide series in the periodic table of elements. He spent most of his career as an educator and research scientist at UCAL- Berkeley, its 2nd Chancellor 1958-61. He advised 10 US Presidents (Truman-Clinton) on nuclear policy and was Chairman of the US Atomic energy Commission (AEC) 1961-71, where he pushed for commercial nuclear energy and peaceful applications of nuclear science. He was a signatory to the Franck Report and contributed to the Limited Test Ban Treaty, the Nuclear Non-Proliferation Treaty, and the Comprehensive Test Ban treaty.

Seaborg was the principal or co-discoverer of 10 elements: plutinium, americum, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, and element 106, which, while he was still alive, was named seaborgium in his honor. He also discovered more than 100 isotopes of transuranium elements and is credited with important contributions to the chemistry of plutonium, originally as part of the Manhattan Project where he developed the extraction process used to isolate the plutonium fuel for the 2nd (Nagasaki) atomic bomb. Early in his career, he was a pioneer in nuclear medicine and discovered isotopes of elements with important applications in the diagnosis and treatment of diseases, including iodine-131, used in the treatment of thyroid disease. After sharing the 1951 Nobel Prize in Chemistry with Edwin McMillan, he received approximately 50 honorary doctorates and numerous other awards and honors and the list of things named after Seaborg ranges from the chemical element seaborgium to the asteroid 4856 Seaborg.
