RUHLMANN & PORTENEUVE ()

Among the collaborators of Jacques-Emile Ruhlmann (1879-1933) was his nephew Alfred Porteneuve (1896 - 1949).
The duo worked together on the Hotel du Collectionneur, which was presented at the 1925 International Exhibition of Modern Decorative and Industrial Arts in Paris. 

After Jacques-Emile Ruhlmann's death, Alfred Porteneuve opened his own workshop and completed the work in progress while taking over the models left by his master.
