Harold G. Free, 73, a longtime official of the Kenwood Golf and Country Club and its president for five years before retiring in 1980, died Sunday at his summer home in Cedarhurst, Md., after a heart attack. He had diabetes.

In 1927, Mr. Free went to work as a land surveyor for the old Kennedy-Chamberlin Development Co., developers of the Kenwood club. He joined the Kenwood Golf and Country Club later that year. He was the club's vice president for more than 25 years before becoming president in 1975.

Mr. Free, who also maintained a home in Bethesda, was a past-president and 25-year member of the Bethesda-Chevy Chase Rotary Club and a member of the Bethesda Chamber of Commerce.

Mr. Free was a native of Davenport, Iowa, and moved to the Washington area in 1927. He earned a bachelor's degree in mechanical engineering at George Washington University and attended the university's law school. He was a Navy officer during World War II.

Survivors include his wife of 41 years, Margaret, of Bethesda and Cedarhurst; three sons, Ronald T. of Houston, Tex., Robert M. of Bethesda, and Douglas J. of Rockville; three daughters, Nancy F. Warren of Rockville, Judith F. Benevento of Billings, Mont., and Martha Heinrich of Gaithersburg; a brother, retired Army Maj. Gen. Richard H. Free of Atlanta, Ga., and six grandchildren.
