Tamara J. Wall, 47, chief counsel of National Labor Relations Board, died Saturday at her home in Washington. She had cancer.

Mrs. Wall was born in Berlin, Germany, of Russian parents. She spent World War II in the Soviet Union. While there, her mother and two brothers died of exposure. She herself lost her toes to frostbite while working on a farm in Siberia.

Her father had moved from Germany to the United States, where he settled in Portland, Ore. With the assistance of an Englishwoman, the future Mrs. Wall left the Soviet Union after the war and joined her father in Portland in 1946.

She graduated from Lewis and Clark College there and was elected the May Festival Queen in her senior year. She then moved to Washington to attend George Washington University law school, from which she graduated in 1960.

After two years in private practice, she was named assistant chief counsel of the House Education and Labor Committee during the chairmanship of the late Rep. Adam Clayton Powell (D-N.Y.). In 1963, she joined the NLRB as an assistant chief counsel. In 1978, she was appointed deputy chief counsel. In July 1979 she was named chief counsel.

Mrs. Wall was the NLRB's liason to the administrative law section of the American Bar Association. She also was Woman's Program Coordinator at the NLRB, a position in which she advised the top management of the agency about "the special concerns of women and (assured) that necessary specific actions were taken regarding equal opportunities for women." She was a member of Executive Women in Government.

Mrs. Wall was a former treasurer of the parent-teacher association of St. Gertrude's School, a school for handicapped children where her daughter was a student.

Her husband, Bill Wall, died several years ago.

Survivors include her daughter, Cindy, of Washington.

The family suggests that expressions of sympathy be in the form or contributions to St. Gertrude's School, 4801 Sargent Rd. NE, Washington, D.C.
