Nina Aikman Smith, 85, a resident of the Washington area for more than 60 years who was active in the Bethesda Presbyterian Church, died of cardiac arrest Saturday at the Bethesda Health Care Center. She had been there for about three weeks and had lived in Bethesda since 1920.

Mrs. Smith was born in Rulo, Neb., and attended the Teachers Normal School in Lincoln, Neb. She later taught at various schools in western Nebraska, including a one-room schoolhouse.

She moved to Washington during World War I and went to work for the War Risk Insurance Agency, whose functions later were taken over by the Veterans Administration.

In 1920, she married Mark Owen Smith, a carpenter and builder, and the couple settled in Bethesda. Mrs. Smith resigned her government job two years later to raise her family. During World War II, she worked briefly for the Civil Service Commission.

Mrs. Smith's activities at the Bethesda Presbyterian Church included serving as the president of the Women of the Church and teaching the Women's Bible Class. She also was a member of the Janey Montgomery Chapter of the Daughters of the American Revolution.

In addition to her husband, of Bethesda, survivors include two daughters, Marjorie S. Burlingame and Elizabeth S. Hall, both of Bethesda; two sisters; seven grandchildren, and two great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Bethesda Presbyterian Church.
