Georges Seurat treated painting as a science, controlling every millimeter of his canvases with formulas drawn from optics and color theory, while keeping a secret family hidden from even his closest friends. He died at 31, yet left behind one of the most recognizable paintings in the world. This episode looks past the dots to examine the mind behind them. We start with a wealthy Paris childhood shaped by a father who lived apart and visited once a week, a rigorous academic education at the Ecole des Beaux-Arts, and two years spent drawing only in monochrome with Conte crayon before he allowed himself to tackle color.

We then follow the rejection of Bathers at Asnieres by the Paris Salon, the founding of the Societe des Artistes Independants with no jury and no awards, and his deep reading of chemist Michel-Eugene Chevreul and physicist Ogden Rood. Chevreul’s law of simultaneous contrast, discovered while troubleshooting a tapestry factory, and Rood’s distinction between additive light and subtractive pigment gave Seurat the basis for chromoluminarism: unmixed dots of pure color placed side by side so the viewer’s eye does the blending. We cover the two years he spent on A Sunday Afternoon on the Island of La Grande Jatte, his 1890 letter laying out a formula for engineering emotion, and the rapid illness that killed him, his infant son, and his unborn child within weeks in 1891.

• Why copying plaster casts gave Seurat the discipline to place millions of dots on a ten-foot canvas
• How a complaint about faded black threads led Chevreul to the law that changed modern color
• Seurat’s formula for gaiety, calm, and sadness using color temperature and line direction
• The hidden life with Madeleine Knobloch and their son, unknown to the artists he worked beside
• His influence on the Cubists, Sondheim’s Sunday in the Park with George, and the famous museum scene in Ferris Bueller’s Day Off
