The Pont Saint-Michel, Paris

Maurice Utrillo (French: [mɔʁis ytʁijo, moʁ-]; born Maurice Valadon; 26 December 1883 – 5 November 1955) was a French painter of the School of Paris who specialized in cityscapes. From the Montmartre quarter of Paris, France, Utrillo is one of the few famous painters of Montmartre to have been born there.

Utrillo was the son of the artist Suzanne Valadon (born Marie-Clémentine Valadon), who was then an eighteen-year-old artist's model. She never revealed the father of her child; speculation exists that he was the offspring of a liaison with an equally young amateur painter named Boissy, or with the well-established painter Pierre-Cécile Puvis de Chavannes, or even with Renoir. (See below under Paternity). In 1891 a Spanish artist, Miquel Utrillo, signed a legal document acknowledging paternity, although the question remains as to whether he was in fact the child's father.

Valadon, who became a model after a fall from a trapeze ended her chosen career as a circus acrobat, found that posing for Berthe Morisot, Renoir, Henri de Toulouse-Lautrec, and others provided her with an opportunity to study their techniques.
