Glenn T. Seaborg was a pioneering nuclear chemist whose work with isotopes and transuranium elements contributed to the development of nuclear technology in medicine, energy, and weapons. His early research on the identification of radioisotopes advanced radiological imaging techniques and radiotherapy; he was the co-discoverer of technetium-99m, one of the most widely used radioisotopes in nuclear medicine. Seaborg's most significant accomplishments resulted from his discovery of a number of transuranic elements, including plutonium, which is used to build the atomic bomb. His contributions to the "atomic age" began during World War II with his work on the Manhattan Project to develop nuclear weapons. His impeccable reputation as a scientist and administrator earned him an appointment as chairman of the Atomic Energy Commission, where he was influential in the development and testing of nuclear energy and weapons and in the establishment of nuclear arms control agreements.
