Miriam Auerbach Wolf, 65, a retired real estate executive and the first woman to become a life member of the "Million-Dollar Sale Club" of the Washington Board of Realtors, died of cancer Sunday at her home in Bethesda.

Mrs. Wolf began her real estate career in 1957. At the time of her retirement in 1976 for reasons of health, she was associate sale manager for the Legum & Berber company. She received several awards from the Board of Realtors for her residential transactions.

In addition to her business activities, Mrs. Wolf was the founder and first president of the Montgomery County Chapter of the National Council of Jewish Women. She also was the first president of the Montgomery County Thrift Shop, the proceeds of which go to various charities.

During the Eisenhower Administration, she served on the women's adivsory committee of the President's Council on the Handicapped.

Mrs. Wolf was born in Washington and graduated from old Central High School. She was a French teacher at Georgetown Day School in the mid-1950's before beginning her real estate work.

Survivors include her husband, Alexander Wolf, Jr., of the home in Bethesda; three sons, Alexander III, of Sykesville, Md., John, of Baltimore, and Christopher, of the home, and one grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the Vincent T. Lombardi Cancer Research Center, Georgetown University Hospital, Washington, D.C.
