Madeline is a children's book series written by Ludwig Bemelmans, an American author of Belgian, Austrian and German origins. The first book in the series, Madeline, was published in 1939. It proved to be a success, and Bemelmans wrote many sequels to the original during the 1940s and 1950s. The series continues to this day, written by Bemelmans' grandson John Bemelmans-Marciano. The books were later adapted into a television series and a feature film. The adaptations are famous for having the closing line, first uttered by actress Ethel Barrymore in a play: "That's all there is, there isn't any more."
