James Edwin (Ed) Hawley (September 27, 1897 – April 20, 1965) was a Canadian geologist and distinguished Professor of Mineralogy at Queen's University.
After completing his Masters, Hawley spent three years working in petroleum geology in Alberta, Ecuador, Burma and India.
His earliest papers in 1929 and 1930, based on research on the generation of oil in rocks by shearing pressures, are classics in the field of petroleum geology.
"Dr. Hawley has brought to geology an incisive, scientific mind and an exceptional knowledge of the basic sciences of chemistry and physics.
On the other hand, he has shown the fallacies of a number of geological hypotheses which cannot be substantiated by established laws of chemistry and physics."
