Phoebe R. Silver, 73, who did clerical work for the federal government during the 1960s and was a member of Congregation Olam Tikvah, a Conservative synagogue in Fairfax City, died Sept. 4 at her home in Concord, Calif.

The former Arlington and Annandale resident had chronic obstructive pulmonary disease, her son, Stephen Aaron Silver, said.

Mrs. Silver did clerical work for several agencies during the 1960s before the birth of her son.

At her synagogue, she was a member of the sisterhood organization and the adult bat mitzvah class of 1980.

Phoebe Rose Korn, a Washington native, appeared in Life magazine as an infant because she was born with two teeth.

A 1955 graduate of Western High School, she took courses at a business school in the District and at Northern Virginia Community College.

During the 1970s, Mrs. Silver volunteered as a teacher’s aide at her son’s schools in Annandale. She also helped lead the effort to preserve the wooded area that became the city’s Backlick Park.

Her husband of 26 years, Samuel R. Silver, died in 1992. A daughter, Sharon Michele Robyn Silver, died shortly after her birth in 1972.

Survivors include her son, Stephen Aaron Silver of San Francisco; one brother; and one grandson.
