In 1967, Konigsburg published two books, Jennifer, Hecate, Macbeth, William McKinley, and Me, Elizabeth and From the Mixed-Up Files of Mrs. Basil E. Frankweiler. She received the 1968 Newbery Medal for Frankweiler but also received the Newbery Honor Award that same year for Jennifer, Hecate. She is the only writer to receive a Newbery Honor and the Newbery Medal in the same year. Then, in 1997, Konigsburg won the Newbery again for The View From Saturday – the 29-year span between the two Newbery Medals is the longest length of time between two Newberys awarded to one author. Konigsburg also can claim something no other writer we can think of can claim: both Ingrid Bergman and Lauren Bacall starred in film and television adaptations of one of her books. Bergman was the title character in From the Mixed-Up Files of Mrs. Basil E. Frankweiler 1974 and Bacall in 1995.
Konigsburg was born in New York City, but grew up in small towns in Pennsylvania, settings that infused her fiction. She told an interviewer that reading was only "tolerated" in her family, "not sanctioned like dusting furniture or baking cookies.” The first in her family to attend college, she was her high school valedictorian. To earn money for college, she worked as a bookkeeper.
Konigsburg was the author of 20 books, approximately half of which she illustrated herself.
