<b>1865 - 1876 / Bruxelles, Rue du Persil, 6 or 4<70-75> (private)</b> Domicile of Louis Joseph from 12.12.1868. The Tarlier directory mentions this address besides that of Rue de l'Ecuyer, but we have found no trace of photographic activity here. A building, constructed in the courtyard from plans by the architect E. Janlet in 1867 and rebuilt in 1873, was used as an exhibition space. In December 1871, Ghémar opened an art gallery in it, in collaboration with Sarah Isabella Harris, widow of his half-brother Léon Louis Auverleaux (see that name), under the collective name of "Ghémar Frères". Fine art auctions were also held here. The Galerie Ghémar operated until its sale, in November 1876, by Ghémar's widow, Marie Cathérine Jadoul (° Brussels - Ixelles, 25.2.1844; + Brussels, 27.8.1882). The interior spaces were remodelled in 1877 and the building has been occupied since 1879 by the masonic lodge "Les Amis Philantropes".
