Mrs. Levin had been president for the past decade and still held the position at her death.

"She came to the monthly meetings of the board with a printed agenda. Meetings were for one hour — from 2 p.m. to 3 p.m. — on the third Tuesday of the month," said Mrs. Frank. "She believed you were wasting time if you couldn't get through the agenda in an hour."

She said that Mrs. Levin was "proud of what the group accomplished" and that she was an "advocate for the library system."

"She'd go before the Baltimore County Council with statistics and argue why the library budget should remain intact," said Mrs. Frank. "She also believed in community partnerships. She was proud of the library system and its mission."

During the past 10 years, Mrs. Levin presided over a speaker's bureau that brought notable figures from the arts, literature, journalism and government to speak, including Gov. William Donald Schaefer.

"Rhoda passed away knowing that she had influenced our group," she said. "And we all loved her."

Mrs. Levin, who lived in Stevenson Village, enjoyed painting still lifes and landscapes in oils. She was an avid reader and liked attending the theater, concerts and visiting museums, where she had been a season ticket holder.

She was also a world traveler.

Services were Wednesday.

Surviving are a daughter, Bonnie Levin of Washington; and a brother, Jerry Powell of Pembroke Pines, Fla.. Her son, Charles Levin, died in 2007. Her companion of 33 years, C. Edgar Thomas Jr. of Towson, died in 2008.

A previous version of this obituary incorrectly stated that Mrs. Levin's companion of 33 years, C. Edgar Thomas Jr. of Towson, survived her. The Baltimore Sun regrets the error.
