Robert M. Garrels, professor of Geology, and Frank H. Westheimer, Morris Loeb Professor of Chemistry, have received $50,000 unrestricted grants from the Petroleum Research Fund, which is administered by the American Chemical Society.

Garrels did research on geochemical problems with the U.S. Geological Survey until 1955, when he joined the Harvard Faculty. A member of the National Academy of Sciences, he was awarded the unsolicited grant for his geological work in the crystallization of minerals, chemical reactions of minerals, and ionic diffusion through rocks.

Westheimer, also a member of the National Academy of Sciences, has conducted research on electrostatic theory, chromic acid oxidation, sterospecificity, and the action of enzymes.
