Charles F. Fuechsel, 77, a former Atlantic regional engineer for the U.S. Geological Survey and a recipient of the Interior Department's Distinguished Service Award, died Friday after being stricken during a bridge game at Rossmoor Leisure World in Silver Spring.

Mr. Fuechsel spent 40 years with the Geological Survey. His assigments included work in Alaska and Venzuela and with the Tennessee Valley Authority before he was transferred to Washington in 1941.

During the World War II, he helped set up what is now known as the survey's branch of special maps. Later he became the first chief of the map information office, chief of the branch of cartography, and chief of the branch of field surveys. In 1958, he became Atlantic regional engineer with responsibilities in 23 states.

Following his retirement in 1965, Mr. Fuechsel received Interior's Distinguished Service award. The citation said he was being "recognized as an outstanding leader who made significant contributions to the improvement of mapping technology" throughout his career.

Mr. Fuuechsel was born in Philadelphia. He graduated from the Pennsylvania State Forest School, now part of Pennsylvania State University, and joined the Geological Survey after working briefly in Alabama.

Survivors include his wife, June, of the home in Rossmoor in Silver Spring, where the couple moved from Airlington in 1971; three sons, John, a Coast Guard Officer stationed in London, England, Robert E. Fox, of Portland, Ore., and Charles F. III, of Mayo, Md.; six grandchildren, and two great - grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Rossmoor World Interfaith Chapel Building Fund, Silver Spring.
