Paul Csar Helleu was a French oil painter, pastel artist, drypoint etcher, and designer, best known for his numerous portraits of beautiful society women of the Belle poque. He also conceived the ceiling mural of night sky constellations for Grand Central Terminal in New York City. He was also the father of Jean Helleu and the grandfather of Jacques Helleu, both artistic directors for Parfums Chanel.
Paul Csar Helleu was born in Vannes, Brittany, France. His father, who was a customs inspector, died when Helleu was in his teens. Despite opposition from his widowed mother, he then went to Paris and studied at Lyce Chaptal. In 1876, at age 16, he was admitted to the cole des BeauxArts, beginning academic training in art with JeanLon Grme. Helleu attended the Second Impressionist Exhibition in the same year, and made his first acquaintances with John Singer Sargent, James McNeill Whistler, and Claude Monet. He was struck by their modern, bold alla prima technique and outdoor scenes, so far removed from the studio. To survive following graduation, Helleu took a job with the firm Thodore Deck Ceramique Franaise handpainting fine decorative plates. At this same time, he met Giovanni Boldini, a portrait painter with a facile, bravura style, who became a mentor and comrade, and strongly influenced his future artistic style.
