Marion Doctor Friend, 74, a Washington resident for 46 years who was active in volunteer and civic work, died Sunday at Washington Hospital Center. She had a heart ailment.

Mrs. Friend was a Gray Lady at the National Naval Medical Center in Bethesda for many years. She served as a volunteer with the Jewish Social Service Agency, the Braille Institute of America and Children's Hospital of D.C.

She was also active in the League of Women Voters and the National Democratic Club and had served as a Democratic Club and had served as a Democratic Party precinct captain in Washington.

Mrs. Friend was born in Chicago and earned a bachelor's degree in art from the University of Chicago.

She was a charter member of the Washington chapter of the Brandeis University Women's Club and established the Philip R. Friend chair of engineering at Brandeis after her husband, Philip R. Friend, died in 1965. Mr. Friend had been an engineer and chartered financial analyst in Washington.

Mrs. Friend was a member of Indian Spring Country Club in Silver Spring.

Survivors include two sons, Philip, of San Francisco, and Lawrence, of Potomac; a daughter, Mary Ann Rachelson, of Rockville, and seven grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Brandeis University or Children's Hospital.
