Glenn Seaborg was a renowned chemist who synthesized elements and isotopes, advised ten U.S. presidents, and played a key role in the Manhattan Project. He was awarded the Nobel Prize for his work in creating artificial elements and restructured the periodic table by introducing the actinide series. Seaborg later focused on nuclear policy and arms control, contributing to the limited test ban treaty. He passed away in 1999, leaving a legacy honored by the naming of element 106, Seaborgium.
