Dr. Moore was a volunteer cancer counselor with the Cancer Counseling Institute in Bethesda. At 99, he enrolled in a physical therapy program that enabled him to continue walking, his daughter said.

His first wife, Jane Brunson Moore, whom he married in 1941, died in 1962. His second wife, Emily Berry Moore, died in 1991.

Survivors include his wife of 20 years, Avis Ogilvy Moore of Gaithersburg; two daughters from his first wife, Susan C. Moore of Lebanon, N.H., and Elizabeth K. Moore of Rockville; three grandchildren; and two great-grandchildren.
