Born in 1931 in Alsace, France, Ungerer became something of a personality in his adoptive city of New York, where he hobnobbed with the likes of Stanley Kubrick and painted the bricks of his Greenwich Village house pink. His early children’s books, The Mellops Go Flying, The Three Robbers, and Moon Man among them, were published in the ‘50s and ‘60s to widespread popular acclaim, and he produced iconic advertising campaigns for the New York Times and the Village Voice. But he shocked and alienated the American mainstream when he left his wife and moved in with a consenting “sex slave,” stating that Pauline Réage’s sadomasochistic novel The Story of O changed his life. Shortly thereafter, he scandalized the establishment by publishing Fornicon, a book of drawings depicting humans copulating with machines. His children’s books were pulled from American shelves, and he went on to illustrate a book about prostitutes and dominatrices in a German brothel — in addition to several more children’s books. Though Ungerer occupies apparently disparate roles, his oeuvre is unified by its simple sophistication. He combines youthful humor with the mature sensibilities of a compassionate adult, approaching the prostitutes in a Hamburg brothel and the villains in a children’s book with the same good-natured equanimity: “they turn out to do a lot of good for society, and you know, why not? You have to give everybody a bit of a chance,” he says of the robbers in The Three Robbers book. The works on display in All in One are delightfully childish but unflinchingly critical, at once aesthetically compelling and intellectually demanding. They are unpretentious but serious, blurring the boundaries between children’s entertainment and adult literature.
