Prof. of Chemistry, University of California, Berkeley, and Leader of Heavy Element Nuclear and Radiochemistry Group, LBNL, (1984-91). Co-founder of Seaborg Institute for Transactinium Science at Lawrence Livermore National Laboratory (LNLL) 1991; Charter Director (1991-1996), Sr. Research Advisor (1996-2007).
Darleane Hoffman gained international recognition for capturing and analyzing elusive transuranic elements (elements heavier than uranium) that typically exist for only short periods, making important discoveries about the nature of fission—the atomic process at the heart of nuclear power.
For years scientists believed that transuranium elements—elements whose atomic number is greater than 92, that of uranium—did not occur in nature, but in 1971 Hoffman published her discovery of small amounts of a plutonium isotope (plutonium-244) in a rock formation that was several billion years old.
Darleane C. Hoffman was born in Terril, Iowa, and completed B.S. and Ph.D. degrees in Chemistry at Iowa State University. There she met and married Marvin M. Hoffman. She joined Los Alamos Scientific Laboratory as a radiochemist in 1953. She conducted groundbreaking studies of the fission properties of fermium-257.
