Retired Army Lt. Col. Samuel T.A. Crawford, 71, a veteran of World War II and the Korean War and owner and operator of the Sam T.A. Crawford Tax Return Service in Fairfax since 1968, died of cardiovascular disease Tuesday at his home in Port St. Lucie, Fla. He also maintained a residence in Fairfax.

Col. Crawford, a native of Altoona, Pa., joined the Pennsylvania National Guard in 1925 and was called to active duty with the Army during World War II. He served in Europe, North Africa, and the Middle East. His last tour of duty before he retired in 1960 was at Fort Belvoir. His decorations include the Soldiers Medal and the Bronze Star.

A member of the American Legion since 1945, Col. Crawford was a former Virginia state commander and a member of the Legion national executive committee. He also belonged to the Veterans of Foreign Wars and the Retired Officers Association.

He was a Mason and a Shriner and a member of the Occoquan chapter of the Order of the Eastern Star and Kena Temple. He was a member of the board of directors of the First Commonwealth Corporation in Richmond.

Survivors include his wife of 51 years, the former Eleanor (Sue) Himes of Fairfax; a daughter, Jacquelyn Dunmire of Port St. Lucie, Fla.; a sister, Evelyn Ling of Altoona; two grandchildren, and five great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Sam T.A. Crawford Memorial Fund, P.O. Box 212, Lorton, Va., 22079.
