William Johnston, a Walters Art Museum official, recalled Siebert's enthusiasm for overseas travel on trips led by his institution's educational staff.
The day an art-study tour was announced, Siebert would walk to the Walters with a deposit, he said.
"The trips became a part of her social life," Johnston said. "She was a very peppy person who had an endearing quality of taking a real interest with those she was accompanying."
Born in Baltimore, Siebert grew up near Druid Hill Park. Friends said that her father, an attorney, taught her values of conservative money management. She lived with her parents at their St. Dunstan's Road residence in Homeland and later with her aged mother at the Carlyle Apartments on University Parkway. She then moved to Broadmead, where she became active in a residents association and helped arrange speakers.
She joined the Pratt staff immediately after her Goucher graduation and was protege of Margaret Alexander Edwards, who founded the library's young adult readers section. Edwards also left her estate to a trust to promote reading.
Pratt colleagues recalled Siebert by her nickname - "Bunny" - and compared her to the "Energizer Bunny." They said she was constantly in motion, but was not a good driver, prone to taking her eyes off the road while pressing a point in conversation. She was also a light eater.
"I'd look at her and say, 'Why are you only having a cube of cheese and a grapefruit for lunch?' said Taylor, her Pratt colleague. "She'd say, 'Because I intend to have two cocktails when I get home tonight.' "
