Jacques Cavallier-Belletrud is a French perfumer currently working for Louis Vuitton within the LVMH Luxury Group. He was born in Grasse, France, a city historically known for its centuries-old perfume tradition. He comes from a family of perfumers—his father and grandfather were also perfumers. He has created or contributed to more than 80 fragrances for fashion houses such as Parfums Christian Dior, Parfums Givenchy, Issey Miyake, Yves Saint Laurent, Fenty Beauty, and Lancôme.
Cavallier is credited with introducing the synthetic molecule Calone 1951 into several of his most successful fragrances, such as Aqua di Gio and L’Eau d’Issey. Calone is known for producing a marine, watery freshness often associated with melon-like nuances. His most successful creations include Giorgio Armani Acqua di Gio and Issey Miyake L’Eau d’Issey.
In 2012, he joined LVMH Luxury Group as an in-house perfumer to develop the first Louis Vuitton fragrance, launched in 2016. LVMH follows the model of dedicated in-house perfumers across its luxury brands, including Jacques Polge at Chanel, Jean-Claude Ellena at Hermès, Mathilde Laurent at Cartier, Thomas Fontaine at Jean Patou, and Thierry Wasser at Guerlain.
