Vivian J. Fagg, 24, a program technician with the National Park Service, died Wednesday at her home in Glen Echo. She had suffered from a neurological disorder.

Born in Nuremburg, Germany, while her father was stationed there with the U.S. Army. Miss Fagg grew up in the Washington area.

She graduated cum laude with a degree in history from Mount Holyoke College in 1974. Between her junior and senior years, she had served as a summer intern with the curator of the U.S. Senate.

After graduation, Miss Fagg became a docent at the National Portrait Gallery and was a volunteer worker at the Park Service's Turkey Run Farm.

She had taken graduate work in art history at the University of Maryland and was enrolled at the University of Virginia to begin work next week toward a master's degree.

She is survived by her parents, Mr. and Mrs. Alfred E. Fagg. and a brother, Alfred Jr., of the home, and a sister, Catherine Proia, of Silver Spring.

The family suggests that expressions of sympathy may be in the form of contributions to a memorial fund in her name for the student internship program of the National Trust for Historic Preservation.
