John R. Johnson, 84, a retired employe of the Internal Revenue Service and an area resident since 1918, died Tuesday at Mount Vernon Hospital in Alexandria after a heart attack.

Mr. Johnson joined the old Bureau of Internal Revenue, a predecessor of the Internal Revenue Service, in 1943. A former supervisor of the collection division, he retired in 1962.

Before joining the Bureau of Internal Revenue, he was manager of the White Motor Co. and the J.W. Birkett Transfer Co. here.

He was born in Austin, Tex., and worked for the Texas State School for the Blind there before moving to the Washington area.

Mr. Johnson was elected clerk of the town of Potomac in 1927 and served in that position until 1931 when the town was annexed by Alexandria.

He served in the Army during World War I.

Mr. Johnson lived in Fairfax County and attended Wesley United Methodist Church in Alexandria. He was a member of the National Association of Retired Federal Employees (NARFE) and Woodmen of the World.

Survivors include his wife, Gertrude E., of Mount Vernon; two daughters, Joyce M. Ware of Front Royal, Va., and Gwendolyn J. Frutchey of Fairfax County; seven grandchildren and six great-grandchildren.
