James Louis Deaver, 60, a Fairfax County businessman and civil leader, died of a cerebral hemmorhage Tuesday at Northern Virginia Doctors Hospital.

He founded and became president of the Star Supply Co. of Annandale in 1946. After adding a store in Fairfax in 1965, the firm took the trading name of American Hardware and Lumber Stores. A third store was added in Herndon in 1975.

A former field adviser to the Small Business Administration, Mr. Deaver had twice run unsuccessfully as a candidate for the Fairfax County Board of Supervisors.

He was a member of the Republican County Committee when he ran in 1955, and was a write-in candidate in the 1959 campaign.

Mr. Deaver served as president of the Annandale Chamber of Commerce in 1952. He was a member of the board of directors of the First Virginia Bank and of its executive committee.

He also was treasurer and a member of the board of the American Supply Co. in Butle, Pa., and a past president of the Hardware Association of Virginia and West Virginia.

He was active in the Boys Scouts and in Little League and Babe Ruth League baseball, and was a member of St. Alban's Episcopal Church in Annandale.

Born in Chicago, he grew up in Seatle and was a graduate of the University of Washington. During World War II he saw service with the Army Air Coprs as an officer with the Air Transport Command.

He is survived by his wife, Joyce Boland Deaver, and a daughter, Elizabeth, both of the home in Annandale; two sons, James P. Louis Jr., of Manassas, and John Terry, of Fairfax, and two grandchilren.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.
