Mary S. Disler, 68, a founder and former executive director of the Fairfax County Council of the Arts who was active in civic and women's groups, died of lymphoma Friday at Fairfax Hospital.

Mrs. Disler was a former president of the Pine Ridge Women's Club, the Northern District of the Virginia Federation of Women's Clubs, and of the Fairfax County Federation of Women's Clubs.

While she was president of the Fairfax County Federation, the Fairfax County Cultural Commission asked the group to conduct a survey of local cultural needs. The Council of the Arts grew out of this effort and was established in 1964.

Mrs. Disler was one of its original board members and also served as its treasurer and secretary. In 1969, she became its executive secretary and held that post until 1972.

In addition, Mrs. Disler was a founder and former president of the Fairfax Hospital Auxiliary and a former board member of the Virginia Association of Hospital Auxiliaries. She also was a founder of the Fairfax County Health Careers Conference, which is held each year for high school students from all over Northern Virginia.

A native of Star, N.C., Mrs. Disler graduated from the Women's College of the University of North Carolina. She moved to the Washington area in 1941 and worked briefly for the Veterans Administration. She then was an administrative assistant to the security officer of the Justice Department until 1944. She had lived in Fairfax since 1955.

She was a member of Holy Trinity Lutheran Church in Falls Church and of its Altar Guild and of the board of the Women of the Church. She also was a member of the Grace Welborn Unit of the National Association of Parliamentarians.

Her husband, Oscar C. Disler, a retired comptroller of the Civil Aeronautics Board, died last January.

Survivors include a son, Jack, of Fairfax; her mother, Annie W. Short of Bowie; two sisters, Dorothy Sheppard of Bowie, and Kathleen Comeford of Mountain View, Calif.; two brothers, Robert Short of Fayetteville, N.C., and Clyde Short of Bethesda, and one grandson.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
