Witherspoon pic

Paul A. Witherspoon was a dynamic and influential leader in hydrologic sciences and an inspiring mentor and lifelong friend to many students and colleagues. He was born on 9 February 1919, in Dormont, Pennsylvania, and his early experiences in visiting underground coal mines with his civil engineer father had a direct and lasting influence on his choice of career. After graduating from the University of Pittsburgh in 1941 with a B.S. in petroleum engineering, he worked for 8 years for the Phillips Petroleum Company before returning to graduate school in 1951 to pursue an M.Sc. in petroleum engineering physics at the University of Kansas. He then accepted a position as head of the petroleum engineering division of the Illinois State Geological Survey in Champaign and pursued a Ph.D. at the University of Illinois at Urbana-Champaign at the same time.

Witherspoon had a seminal influence on the development of ideas and methodologies related to the hydrogeology of fractured rocks, the role of aquitards in hydrogeological systems, and the thermohydrologic and hydromechanical couplings in geothermal systems and nuclear waste isolation. In 1977, working from his faculty position at the University of California, Berkeley, Witherspoon initiated and organized the Earth Sciences Division (ESD) of the Lawrence Berkeley National Laboratory (LBNL), served as its first director, and contributed to making it one of the most prestigious Earth sciences institutes in the world on environmental sciences, climate sciences, and subsurface energy resources.

Witherspoon was widely honored for his work. He was awarded the Horton Medal from the American Geophysical Union (AGU) and both the Meinzer Award and the Distinguished Service Award from the Geological Society of America. He was elected in 1989 to the U.S. National Academy of Engineering, in 1992 as a Foreign Member to the National Academy of Sciences of Ukraine, and in 2001 as a Fellow of the World Innovation Foundation.

In 2015, AGU established the Paul A. Witherspoon Lecture in Hydrologic Sciences. The award is intended to promote and reward excellence and outstanding achievements by a midcareer scientist (within 10 to 20 years postdoctoral) in advancing the field of hydrologic sciences.
