Later career and personal life

Seurat concealed his relationship with Madeleine Knobloch (or Madeleine Knoblock, 1868–1903), an artist's model whom he portrayed in his painting Jeune femme se poudrant. In 1889, she moved in with Seurat in his studio on the seventh floor of 128 bis Boulevard de Clichy.

When Madeleine became pregnant, the couple moved to a studio at 39 passage de l'Élysée-des-Beaux-Arts (now rue André Antoine). There she gave birth to their son, who was named Pierre-Georges, on 16 February 1890.

Seurat spent the summer of 1890 on the coast at Gravelines, where he painted four canvases including The Channel of Gravelines, Petit Fort Philippe, as well as eight oil panels, and made a few drawings.
