Nobody made the transition from 1900 to 1925 more gracefully or with more respect from his contemporaries than DUFRENE.

He became a founder-member of the Salon des Artistes Décorateurs in 1904, through which he exhibited for thirty years. He taught Composition at the Ecole Boulle and other institutions from 1912 to 1922, in 1919 returning to the Salons as an independant decorator.

The furniture was neat and logical, much of it embellished with a recurring carved scroll motif today frequently misattributed to SÜE et MARE. Further decoration was provided by marquetry floral medallions in boxwood, ebony and ivory. The effect was a trifle feminine, even effete, a characteristic of DUFRENE's furnishing in the 1920s.

In 1921 he was appointed artistic decorator of La Maîtrise. At the 1925 Exposition he was, simply, everywhere. Apart from his directorship of La Maîtrise pavilion, he designed the petit salon in the Ambassade Française and the entire row of shops on the Alexander III bridge.

The 1930s were no less frenetic. The earlier predilection for wood gave way gradually to metal and glass. Approaching sixty years of age, DUFRENE could still adapt, as he showed during the demise of Art-Nouveau a quarter of century earlier. He died in Nogent-sur-Marne in 1955.
