E. L. Konigsburg

The writer and illustrator E. L. Konigsburg (1930-2013) is one of the most celebrated writers of books for children and young adults. She is the only author to have won the Newbery Medal and Newbery Honor in the same year - a feat she achieved in 1968, for The Mixed-Up Files of Mrs. Basil E. Frankweiler and Jennifer, Hecate, Macbeth, William McKinley, and Me, Elizabeth, respectively. Not only that, but she won the Newbery Medal again almost thirty years later, for The View from Saturday.
