J. Barton Zimmerman, 67, a retired civilian computer analyst with the Department of the Army, died of respiratory failure Saturday at Fairfax Hospital.

Mr. Zimmerman moved to Washington from his native Philadelphia in 1938 and began his government career with the Railroad Retirement Board, working his way up from punch-machine operator to administrator. During World War II, he was a Navy petty officer. He then went back to the board and was assigned to its Chicago office for four years.

In 1950, Mr. Zimmerman returned to Washington and became a computer operator in the Department of the Air Force. Subsequently, he worked briefly for the Department of Agriculture. In 1953, he joined the Department of the Army as a computer analyst in the old Army Signal Corps. He was an analyst with the Computer Systems Support and Evaluation Command when he retired in 1969.

Mr. Zimmerman also had been an Army representative on General Services Administration negotiation panels that purchased computers for government use.

He was a resident of Alexandria and a member of the Glebe Masonic Lodge in Arlington and the Kena Temple Shrine.

Survivors include his wife, Flora K. of Annandale; a son, Bruce B. and a daughter, Donna L. Fortier, both of Springfield; a brother, Harry of Philadelphia, and one grandchild.
