In his long-running Village Voice comic strip and in his many plays and screenplays, he took delight in skewering politics, relationships and human nature. In the mid-1950s, Norton Juster, a neighbor of Mr. Feiffer’s in Brooklyn, invited him to illustrate a children’s book he was writing, “The Phantom Tollbooth.” An ingenious kaleidoscope of wordplay arguably akin in style to Lewis Carroll, the book, published in 1961, was an instant hit. Later in life he derived great pleasure from writing and drawing children’s books, some in collaboration with his daughter Kate, among them “The Man in the Ceiling” (1993), “Bark, George” (1999), “By the Side of the Road” (2002), “The Daddy Mountain” (2004) and “A Room With a Zoo” (2005). A 2010 reunion project with Mr. Juster, “The Odious Ogre,” was warmly reviewed.
