G. Pearl Pollack, 94, a board member of the Jewish Community Center in Rockville and an advocate for senior citizens, died July 29 at her home in Rockville after a stroke.

Mrs. Pollack was president of the JCC's Seniors Organized for Change and the Thursday Senior Adult Club. She often wrote letters to and met with local, state and federal officials on issues concerning senior citizens.

She was a member of the Montgomery County Commission on Aging as well as Interages, a nonprofit group that brings older adults and youths together for such activities as tutoring and mentoring.

For one activity in 1987, she participated in an intergenerational law class at Richard Montgomery High School. She portrayed one of two grandmothers -- the other was played by a 17-year-old student -- involved in a bitter child custody trial. The class offered an opportunity for students and seniors to confront stereotypes about each other and to discuss issues such as corporal punishment and child custody rights and responsibilities.

Through the JCC, she worked with children and taught them old games and songs from her childhood in New York.

When Russian immigrants began moving to the Rockville community in the 1980s, Mrs. Pollack volunteered to help smooth their transition by organizing musicales and discussion groups.

In 1990, Mrs. Pollack received a distinguish service award from the JCC. She also was honored with the G. Pearl Pollack Endowment Fund for Senior Adult programs.

Gertrude Pearl Cooper was born in New York City and was influenced by her grandmother to make life better for others. She graduated from New York University as a physical education major. While at NYU, she danced with two of the founders of the modern dance movement, Martha Hill and Martha Graham.

She received a master's degree in early childhood education from Columbia University in the mid-1940s and a master's from NYU in guidance and counseling in the early 1960s.

She was on the staff of the Hebrew orphan asylum in Manhattan, a nursery school director at Temple Beth El in Rockaway Beach, N.Y., and a physical education teacher at Long Island City High School in Queens, N.Y., where she later became a guidance counselor. She retired in 1977 and moved to the Washington area in 1979.

Mrs. Pollack was a member of Congregation Har Shalom in Potomac.

Her husband of 26 years, Abraham Pollock, died in 1962. A son, Ira E. Pollack, died in 1992.
