"I think most of us are outsiders," she said. "And I think that's good because it makes you question things. I think it makes you see things outside yourself."
Her stories were also adapted for movies and television. Ingrid Bergman starred as Mrs. Frankweiler in a 1973 film adaptation of Konigsburg's book called "The Hideaways."
Konigsburg grew up in Pennsylvania and graduated from Carnegie Mellon University with a degree in chemistry. She married David Konigsburg in 1952, and the couple lived in several cities before settling in the Jacksonville, Fla., area.
Konigsburg, who had two sons and a daughter and five grandchildren, started writing and illustrating children's books when her youngest child began kindergarten. Her husband died in 2001.
