In 1969 Joan Root (Mrs. Stanley W., Jr.) served as vice chairman of the Museum Guides Program, which at that time operated as the Volunteer Guides. By the 1970-1971 annual report, which appears to be the first issue to record all the volunteer guides, Mrs. Root is listed as chairman of the weekday program. She chaired the program until 1974. Mrs. Root was also a member of the Women's Committee, and served as its President from 1977 to 1979. She remained an active member of the Committee until 1996, and continues today as a sustaining member.
