In 1872, Édouard André had repurchased the Gazette of the Art schools and taken the direction of the central Union of decorative arts. It conceived the project then to constitute a collection of tables, sculptures, tapestries and objets d'art of the XVIIIe century. In 1881, Édouard married Nélie Jacquemart, a young painter. This one joined the projects of her husband. Together, they constituted their collection, Nélie methodically also being interested in the Rebirth, in particular Italian, like with primitive of XVe century. In parallel, they arranged their residence to emphasize best possible their acquisitions. In 1894, Édouard died, leaving in Nélie completion future museum.
