For more than forty years, the books Maurice Sendak has written and illustrated have nurtured children and adults alike and have challenged established ideas about what children's literature is and should be. The New York Times has recognized that Sendak's work "has brought a new dimension to the American children's book and has helped to change how people visualize childhood." Parenting recently described Sendak as "indisputably, the most revolutionary force in children's books." Winner of the 1964 Caldecott Medal for Where the Wild Things Are, in 1970 Sendak became the first American illustrator to receive the international Hans Christian Andersen Award, given in recognition of his entire body of work.
