Ghiorso standing by the 104 Wheel, March 7, 1969. Albert Ghiorso (July 15, 1915 - December 26, 2010) was an American nuclear chemist. In the early 1940s, Glenn Seaborg moved to Chicago to work on the Manhattan Project. He invited Ghiorso to join him, and for the next four years Ghiorso developed sensitive instruments for detecting the radiation associated with nuclear decay. After the war, Seaborg and Ghiorso returned to Berkeley, where they and colleagues used the 60" Crocker cyclotron to produce elements of increasing atomic number by bombarding exotic targets with helium ions. He is credited with having co-discovered the following elements: Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium, Lawrencium, Rutherfordium, Dubnium, and Seaborgium. He died in 2010 at the age of 95.
