Kahnweiler notes: "Derain, too, had abandoned decorative light painting in 1907", Kahnweiler writes, "preceding Braque by a few months. But from the outset, their roads were diverse. Derain's endeavor to retain fidelity to nature in his painting separates him forever from Cubism, no matter how closely his ideas may otherwise parallel those of Braque." And Derain was not the only one to venture along the path of Cézanne, only to turn away from it in the coming years. Chagall, Friesz, Matisse, Dufy, Redon, Vlaminck and Modigliani

Paul joined the Rhodesian police force, the British South Africa Police, in 1927, and during patrols in his early years became enamored of the local landscape. Self-taught as an artist, he would often bring his sketchbook along on his trips, recording the passing countryside. He was encouraged to paint by John Piper and Ivon Hitchens, who introduced him to the work of Georges Braque and other painters. Paul retired from the force in 1951 to paint full-time.
