Charles S. ReVelle, 67, professor at Hopkins

BALTIMORE (AP) — Charles S. ReVelle, a Johns Hopkins University professor whose mathematical models helped choose sites for projects ranging from warehouses to reservoirs, died Aug. 10 at his Baltimore home of lymphoma. He was 67.

Mr. ReVelle originally was a chemical engineer, but later turned to applied mathematics and specialized in environmental systems analysis.

Mr. ReVelle is credited with starting the field of location analysis. His algorithms were used to determine the best and most environmentally friendly sites for sewage-treatment plants, warehouses and nature preserves and the best transportation and power grid routes.

His models were later applied to historical questions, such as the location of military legions within the Roman Empire and to modern-day problems of nuclear arms control.



Mr. ReVelle was born in Rochester, N.Y., and earned his undergraduate degree and doctorate at Cornell University. His 1967 dissertation focused on disease prevention and the allocation of drugs and resources for fighting tuberculosis within a group of developing countries. He taught at Cornell before moving in 1971 to Hopkins, where he taught in the geography and environmental engineering department.

With his wife, Penelope L. ReVelle, a biochemist, he wrote a series of college-level environmental textbooks.

Other survivors include two daughters, Cynthia ReVelle of Boston, and Elizabeth ReVelle of Australia; and two brothers, Douglas ReVelle of Los Alamos, N.M., and Jack ReVelle of Orange, Calif.
