Maurice Sendak, Shel Silverstein Publish Books Two beloved children's authors, Maurice Sendak ("Where the Wild Things Are") and Shel Silverstein ("The Giving Tree") have new books out. Silverstein's "Every Thing on It" was published posthumously, while Sendak's "Bumble-Ardy" is raising hair and hackles. Silverstein died in 1999. He had a colorful history and raised a few eyebrows. He is as well-known for his drawings as he is for poetry. After joining the armed services and serving in the Korean War, Silverstein became a cartoon illustrator for "Playboy" magazine. Silverstein was a folk singer and guitarist. He wrote what would become Johnny Cash's only silly song: "A Boy Named Sue." Read more.
