French painter, born at Lorry-les-Metz. From school-days he was a friend of Denis and Vuillard (whose sister he married in 1893) and he met Bonnard at the Académie Julian in Paris, where he enrolled in 1888. With these and several other friends he formed a group of Symbolist painters called the Nabis. The group drifted apart after its last exhibition in 1899 and from this time Roussel concentrated on bucolic subjects from pagan antiquity, painted in a late Impressionist manner, with nervous brushwork and sparkling colours. He also did several large decorative commissions, including a curtain for the Théâtre des Champs-Elysées, Paris (1913), and murals for the Palais des Nations at Geneva (Pax Nutrix, 1936) and the Palais de Chaillot in Paris (La Danse, 1937).
