Elaine Lobl Konigsburg was an American writer and illustrator of children's books and young adult fiction. She is one of six writers to win two Newbery Medals, the venerable American Library Association award for the year's "most distinguished contribution to American children's literature."
Konigsburg submitted her first two manuscripts to editor Jean Karl at Atheneum Publishers in 1966, and both were published in 1967: Jennifer, Hecate, Macbeth, William McKinley, and Me, Elizabeth and From the Mixed-Up Files of Mrs. Basil E. Frankweiler. They made her the only person to be Newbery Medal winner and one of the runners-up in one year. She won again for The View from Saturday in 1997, 29 years later, the longest span between two Newberys awarded to one author.
For her contribution as a children's writer Konigsburg was U.S. nominee in 2006 for the biennial, international Hans Christian Andersen Award, the highest international recognition available to creators of children's books.
