Glenn Seaborg was American chemist known for his synthesis of heavy chemical elements: plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, and nobelium. He helped configure the periodic table as we now know it by placing the actinide series under the lanthanide series.

Seaborg shared the 1951 Nobel Prize in chemistry with American physicist Edwin McMillan. The chemical element with atomic number 106 is named for Glenn Seaborg with the name seaborgium (Sg) in his honor [local].
