Born in Paris 1930. French sculptor, writer, stage designer and film maker. She spent the first twenty years of her life in New York. A self-taught artist, on her return to Europe she began to work in a style similar to Art Brut. Came to public attention through the Shots series (1960-61) ironic parodies of Art informel painting, comprising plaster reliefs using pockets of paint which burst when fired at by visitors to the exhibition, thus staining the surface. Through these works she became associated with "Nouveau Realisme".

She produced reliefs and sculptures made of "found objects" and plastic toys. These were extremely playful and imaginative. Other themes in her work include monsters and other fantastic creatures, such as King Kong (Stockholm, 1963). Other assemblages were in the form of altars.
