"If you played any military music or a Sousa march, it would bring her to tears," he said.
Mrs. Klingaman was a dog fancier, and one of her environmental interests was the wolf.
"She was a staunch environmentalist and an advocate for them. She got interested in them in the early 1970s through her teaching of ecology and because dogs had evolved from wolves," her son said.
"Ann felt they were a very important part of the ecosystem, and she even conducted fundraisers to raise money for their protection," said Mrs. Boner.
For the past 12 years, Mrs. Klingaman lived at Vantage House retirement community in Columbia, where she wrote profiles of new residents for its monthly newsletter.
She had been a longtime member of and Sunday school teacher at Catonsville Presbyterian Church, where she was ordained a deacon in 1986.
Mrs. Klingaman was an avid gardener. She also enjoyed knitting shirts for teddy bears that were sold to raise funds for charities.
She was an Abraham Lincoln and Civil War buff, her son said, and also a collector of keys.
A memorial service will be held at 11 a.m. Aug. 25 at her church, 1400 Frederick Road.
In addition to her son, Mrs. Klingaman is survived by another son, William Klingaman of Columbia; three grandchildren; and many nieces and nephews.
