Maurice Sendak is best known as the award-wining author of “Where the Wild Things Are.” His new book, “Brundibar” is a collaboration with playwright Tony Kushner. It’s a story about confronting evil, based on events from the Holocaust. Sendak tells Steve Paulson that as a Jewish child in New York, he was completely aware of the fate of the Jews in Europe, which contributed to his view of childhood as a frightening time.
