Carl T. Noll, 64, head of the National Cemetery System of the Veterans Administration since 1977, died of a brain tumor Tuesday at the Camelot Nursing Home in Arlington, where he had been a resident for about a week. He lived in Arlington.

A former employe of the Department of the Army, he transferred to the VA when the National Cemetery System became part of that agency in 1973. Named deputy director of the system in 1975, he had been instrumental in the first expansion of the system in nearly a quarter of a century.

Mr. Noll was born in Coatesville, Pa. He graduated from Eckles College in Philadelphia and later attended George Washington University. During World War II, he served in the Army in the China-Burma-India theater.

After the war, he became a civilian executive with the Army Quartermaster General's office and helped in the repatriation program for the dead of World War II. During the Korean and Vietnam conflicts, he devised a system of field mortuaries in combat zones and established a central identification laboratory in Japan.

His honors included the President's Meritorious Executive Rank Award, the VAs Exceptional Service Award, the Army's Meritorious Civilian Service Award and the Army's Exceptional Civilian Service Award.

Mr. Noll was a member of the American Legion, the Veterans of Foreign Wars, the Disabled American Veterans and the AMVETS. He belonged to the Resurrection Lutheran Church of Arlington, the Leesburg Golf and Country Club and the Scottish Rite of the Masons. He had been president of the Arlington Funeral Home since 1956.

Survivors include his wife, the former LaVern Bartholomew of Arlington; a daughter, Kathryn Weekly of Grafton, W. Va.; and two sisters, Dorothy Long of Coatesville and Ruth Nichols of Williamsport, Pa.
