Description
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, including spontaneous fission. 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 invented numerous techniques and machines for isolating and identifying heavy elements atom-by-atom. He is generally credited with implementing the multichannel analyzer and the technique of recoil to isolate reaction products, although both of these were significant extensions of previously understood concepts. He is credited with having co-discovered the following elements Americium (element 95), Curium (element 96), Berkelium (element 97), Californium (element 98), Einsteinium (element 99), Fermium (element 100), Mendelevium (element 101), Nobelium (element 102), Lawrencium (element 103), Rutherfordium (element 104), Dubnium (element 105), and Seaborgium (element 106). He was famous among his colleagues for his endless stream of creative "doodles," which define an art form suggestive of fractals. He also developed a state-of-the-art camera for birdwatching, and was a constant supporter of environmental causes and organizations. He died in 2010 at the age of 95.
