Jean-Henri Jansen established his business in 1880. He relocated to 9, rue Royale, Paris, in 1885. He became Fournisseur de la Cour d'Espagne, manufacturing furniture in the old and new styles. He was awarded a Silver Medal at both the 1883 Amsterdam Exhibition and the Paris 1889 Exposition Universelle. He took over Zwiener's business renaming it Zwiener Jansen Successeur and signing pieces, as can be seen in this lot ZJ.
Joseph-Emmanuel Zwiener was born in Herdon, Germany, in 1849. He moved to Paris and established his workshop at 12, rue de la Roquette and is recorded as working from that address between 1880 and 1895.
He produced the very finest furniture replicating articles from the Garde-Meuble National of France. His work appears to be mainly in the Louis XV rococo manner, inset with fine marquetry, Vernis Martin panels and encrusted with gilt-bronze mounts, all to the highest standards of manufacture. However, the furniture that he created was in a very, florid and elaborate Louis XV style.
Exhibiting at the Exposition Universelle, Paris in 1889, he was awarded a gold medal. The jury reported 'dès ses débuts à une Exposition universelle, [il] s'est mis au premier rang par la richesse, la hardiesse et le fini de ses meubles incrustés de bronze et fort habilement marquetés'.
