Gleen T. Seaborg (1912-1999) was a co-recipient of the 1951 Nobel Prize in Chemistry for his work as co-discoverer of elements#94 Plutonium (in 1941), #95 Americium, #96 Curium, #97 Berkelium and #98 Californium. Later, he played a part in creating elements #99 Einsteinium, #100 Fermium, #101 Mendelevium and #102 Nobelium. In 1994, a new element (#106 Seaborgium) was named after him, the first time the honor has been bestowed upon a living person.

He chaired the Atomic Energy Commission (1961-1971) and helped negotiate the nuclear test ban treaty of 1963. Pencil notes (unknown hand) at left margin. Signature lightly smudged.
