IN MEMORIAM: Professor of geosciences emeritus KENNETH DEFFEYES *59 died Nov. 29 in La Jolla, Calif. He was 85. A geological engineer, chemical oceanographer, and sedimentary petrologist, Deffeyes joined the Princeton faculty in 1967 and transferred to emeritus status in 1998. He helped reshape the curriculum at Princeton as his field began to incorporate plate tectonics into studies of Earth’s formation. He wrote three books, including When Oil Peaked, which built on the theory that U.S. oil production would peak and decline.
