Edward Irving Wortis (born December 23, 1937), better known by the pen name Avi, is an American author of young adult and children's literature. He is a winner of the Newbery Medal and twice one of the runners-up (Newbery Honor). Biography Avi and his twin sister were born in Brooklyn, New York to Joseph Wortis, an American-Jewish psychiatrist of Russian-Jewish and Alsatian-Jewish descent, and Helen Wortis, a social worker. When he was one year old, his sister gave him the nickname "Avi". Two of Avi's grandfathers were writers, and one grandmother was a playwright. In interviews, he recalled his mother reading to him and his sister every night, and going to the public library on Fridays. He is also the first cousin of the Academy Award-winning actor Alan Arkin. Avi's parents transferred him from Stuyvesant High School to Elisabeth Irwin High School, a smaller private school. At his new school, he studied with a tutor, Ella Ratner, whom he credits for his writing success. He struggled in school due to suffering from dysgraphia, a writing disorder. Avi has written 80 books, almost entirely for children and young adults. Along with The True Confessions of Charlotte Doyle, he has written books for different age groups and in many different genres including historical fiction, fantasies, graphic novels, comedies, mysteries, ghost stories, adventure tales, realistic fiction, and picture books. Avi has won awards for some of his books, including a Newbery Honor for The True Confessions of Charlotte Doyle in 1991 and another for Nothing but the Truth in 1992. His fiftieth book, Crispin: The Cross of Lead, was awarded the Newbery Medal in 2003. Avi's book Iron Thunder, about the ironclad Monitor and its battle with the CSS Virginia in Hampton Roads, Virginia, was selected as the 2009 Beacon of Freedom Award winner by Williamsburg Regional Library and Colonial Williamsburg Foundation.
