Natalie Stern Rosenstein, 98, a community volunteer, died Tuesday at the Quadrangle in Havertown.

Mrs. Rosenstein graduated from Philadelphia High School for Girls. She earned a bachelor's degree from Goucher College in Baltimore. In 1934, she married Louis C. Rosenstein, an engineer whom she met at a party in Philadelphia.

While raising their two children in Philadelphia, Mrs. Rosenstein was a volunteer for Family Services in Philadelphia, for Philadelphia public libraries, and for the library at her synagogue, Congregation Rodeph Shalom in Philadelphia. She was also a fund-raiser for several charities.

After moving to Elkins Park in 1958, she served on the board of Elkins Park Library. In the 1960s and 1970s, she was a member of the Alpha Auxiliary of the Central Montgomery County Mental Health and Mental Retardation Center in Norristown. She devoted long hours to working with retarded youngsters who had speech, reading and writing difficulties, her son James said.

She had an abiding concern for people, the world, and particularly for her husband, their children, and their extended families, he said.

Mrs. Rosenstein loved playing bridge, studying and collecting antiques, and listening to classical music.

She and her husband moved to the Quadrangle retirement community in 1992. He died in 2002.

In addition to her son, she is survived by a daughter, Joan Rosenstein Roberts, and a sister.

A graveside service will be at 11 a.m. today at Roosevelt Memorial Park, 2701 Old Lincoln Highway, Trevose.
