The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.

Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.
