Thomas V. McEvilly

Professor of Seismology, Emeritus, UC Berkeley
Earth Sciences Division Director 1982 to 1992

In Memoriam – September 2, 1934 — February 22, 2002
University of California’s In Memoriam published by the Academic Senate

In the 1970s Tom McEvilly began working with the Earth Sciences Division on the exploration for new sources of geothermal energy, which involved a number of geophysical investigations in California, Nevada, and Mexico. His research covered a broad range of topics, mostly in the field of seismology. They included studies of crust and upper mantle structure, detailed investigations of earthquake sources around the world, exploratory studies of geothermal energy, contributions in support of a nuclear test ban treaty, tests of earthquake prediction scenarios, application of seismic reflection methods to a variety of tectonic problems, and use of controlled sources to measure anisotropy and temporal changes in seismic velocity. McEvilly obtained his Ph.D. in Geophysical Engineering from St. Louis University in 1964.

Paul A. Witherspoon

Senior Faculty Scientist, LBNL
Professor Emeritus, UC Berkeley

Earth Sciences Division Director 1977 to 1982

In Memoriam – February 9, 1919 — February 10, 2012

The Division was founded on July 21, 1977, when then Lab Director Andrew Sessler signed a letter enacting its creation. Earth Sciences was an outgrowth of the Energy and Environment Division, which was formerly known as the Environmental Energy Technologies Division. ESD’s first director was Paul Witherspoon, who transferred the Geothermal and Geosciences Program and other research areas from the Energy and Environment Division to formulate the technical scope of the Earth Sciences Division. Witherspoon’s research included reservoir engineering, geochemical and production engineering, geophysical studies and land subsidence research (related to the impact of geothermal wells) and applied it to geothermal activities and nuclear waste isolation projects. Witherspoon received his Ph.D in petroleum engineering physics at the University of Illinois, Urbana in 1956. For more information about Paul Witherspoon, go to his profile at
