Richard Gray

Richard (Dick) E. Gray, P.G., is internationally known in geotechnical engineering, engineering geology and subsidence engineering. His consulting experience includes numerous geotechnical studies of sites for large industrial developments, such as steel mills and fossil-fuel, hydroelectric, and nuclear power plants. He has been responsible for numerous studies of slope stability, subsidence, seismicity, ground water, mineral evaluation and waste disposal, and the design of dams, foundations snd tunnels.  Dick earned a bachelor's degree in civil engineering from Carnegie Institute of Technology, now Carnegie Mellon University, in 1956. After graduation he continued working with

E.D'Appolonia, his professor in soil mechanics and foundation engineering. In April 1957 he began a six-month assignment as a lieutenant in the U. S. Army Corps of Engineers; he rejoined Dr. D'Dappolonia in the fall of 1957. While working full-time he undertook graduate study in geology at the University of Pittsburgh. Initially a qualitative geology department, in a few years it transformed into a quantitative group. During this time, Dick was able to take essentially all courses offered in the old and new programs. This was an exciting time in geology as the concepts and understanding of plate tectonics developed.

Dick was also fortunate to be exposed to the teachings of the world's best specialists in soil mechanics and foundation engineering (Terzaghi, Peck, Lambe, Casagrande, Seed, Bjerrum, and Skempton) during several summer courses (1958 and 1959) at the Massachusetts Institute of Technology (M.I.T.) in what has become Geotechnical Engineering. Beginning in 1961 he participated in the early U. S. conferences on rock mechanics and the first (1966) and second (1970) congresses of the International Society of Rock Mechanics.
