Rose Rice, 91, a suffragette and social reformer, died Monday at Northern Virginia Doctors Hospital. She had been a resident of Northern Virginia for the past 20 years.

Born in Austria, Mrs. Rice came to this country in her early teens and settled in New York. She married Dr. Lewis Rice, a dental surgeon, who died two years ago.

Mrs. Rice was among the first women to bob her hair as a symbol of emancipation. While she was in her 20s, she helped organize students of Vassar College to march in support of the newly formed Women's Trade Union League.

She was an active member of the Women's International League for Peace and Freedom.

While in New York, Mrs. Rice founded the Henry Street Visiting Nursing Service of Northern Queens in 1920, and was its honorary life president. Her volunteer service with the American Red Cross was recognized when the Rose Rice Gray Lady Unit in Queens was named in her honor.

After coming here, Mrs. Rice was active as a fund raiser for Children's Hospital and the Heart Fund.

She is survived by two daughters Cynthia Nathan, with whom she lived in Arlington, and Elizabeth Friedman, of East Hampton, L.I., and two grandchildren.
