At a time when niche perfumery (or designer perfumery, as opposed to mainstream perfumery) is still in its early stages, with brands such as By Killian, Le Labo, Frédéric Malle, etc., Gérald Ghislain founds Histoires de Parfums.

He creates a collection of perfumes that reflect his personality, rich in temperament and distinctly romantic.
