"She worked on the Bloodmobile," said her son Peter U. Musser.
She was passionate about Philadelphia's arts and culture. "She loved going to the ballet, and donated to the Pennsylvania Ballet," her family said in a statement.
She cofounded the guide program and acted as benefactor for the Philadelphia Museum of Art. She supported the Rodin Museum and the Barnes Foundation.
In the suburbs, she donated a room for art display at the Wayne Art Center and served on the board of the People's Light and Theater Company in Malvern.
She was a generous supporter of her alma mater, serving on the board for many years and spearheading the new Musser Dormitory building project, and creation of the Kaleidoscope Theatre, the Berman Museum, and the Center for Bees. The college responded by bestowing upon her an honorary doctorate of letters.
Mrs. Musser was a 40-year member of the Main Line Unitarian Church, where she created a resource room for children. She taught at the Schuylkill Center for Environmental Education and supported its wildlife center, which treats injured animals and, when well, returns the creatures to the wild.
She loved playing golf, reading, and spending summers in the Poconos.
Surviving, beside her son, are a daughter, Joan Vaughan; five grandchildren; and a great-grandchild. Another son, Craig, died in 1986.
A memorial service will be at 10:30 a.m. Friday, Feb. 13, at the Main Line Unitarian Church, 816 S. Valley Forge Rd., Devon. Interment is private.
Contributions may be made to the Schuylkill Center for Environmental Education, 8480 Hagys Mill Rd., Philadelphia, Pa. 19128, or to the Wayne Art Center, 413 Maplewood Ave., Wayne, Pa. 19087.
