Marie Laurencin
Léonce became a noted champion of Cubism, a lead that Paul followed, but being located in a more noted art district, he gained better contacts and greater finances. Working initially with his brother-in-law Daniel-Henry Kahnweiler, Paul and his partner Georges Wildenstein established and then won over from Kahnweiler exclusive relationships with: Picasso (from 1918); Braque (1922); Marie Laurencin; Fernand Léger (1927); and latterly Matisse (1936).
