E.L. Konigsburg, an award-winning author and illustrator of children's books, has died. She was 83.

Her son Paul Konigsburg says the author died Friday at a hospital in Falls Church, Va. She had suffered a stroke a week before she died.

She won the John Newbery Medal in 1997 for her book "The View from Saturday" and in 1968 for "From the Mixed-Up Files of Mrs. Basil E. Frankweiler." The Newbery is one of the top honors for children's literature. Her family says she wrote 16 children's novels and illustrated 3 picture books.

Ingrid Bergman starred as Mrs. Frankweiler in a 1973 film adaptation of Konigsburg's book called "The Hideaways."

She lived for many years in the Jacksonville, Fla., area.
