Henri Jansen, who was of dutch origin opened a furniture store in rue Royale around 1880. He then installed his cabinet makers joiners, sculptors, painters, gilders, chisellers, upholsterers and bronzesmith in a small workshop rue Pergalèse in Paris too.
He made a name for himself with his restoration of the Laeken Palace in Belgium. This was the first of many realisations for the Belgian Royalty as well as for other royal european families.
By this time all the most prestigious names (Coco Chanel, Rothschild, ...) met in Jansen's, which became world famous.
Following this success Jansen opened a new store, 9, rue Royale and a larger workshop rue Saint-Sabin.�
This success continued after the First World War and even after the death of Henri Jansen in 1929 when the succession was taken over by Schwartz until 1936. By then the Jansen store were established in many cities all over the world, London, New-York, Prague, Roma, Cairo...
The last International Exhibition of the house of Jansen was in 1937 in Paris where the stand was near to that of Leleu with whom Jansen was later merge.
The visitor to the exhibition could admire the latest realisations, objects and furniture much cherised by the house of Jansen.
The research was very important to the house of Jansen and it didn't hesitate, after the First World War, to acquire many important pieces in order to protect the French Patrimony.
Following the war he was joined by the designer Albert Cazes as well as by Stéphane Boudin followed by Pierre Delbée who managed the house� after the death of Henri Jansen.
the main activity around 1945 was concentrated on the production of camouflage and the formation of decorators in the Centre of Arts and Techniques lent, to the house of Jansen by the Central Union of Decoration Arts.
In 1971 Jansen merged with Leleu-Deshays but it's style, it's tradition, quality and it's taste for excellent work stayed unchanged.
For twenty years with Pierre Delbée, the house of Jansen continued to follow all the contemporary tendencies and afterwards the expansion of Jansen was assured with the new President Pierre Deshays.
This developpement was marked by the last fantastic Jansen realisation, the lay out, in 1971, of the Persepolois site on the occasion of the 2500 year anniversary of the Persian Empire.
