Born in Grasse in the cradle of perfumery, Jacques Cavallier Belletrud recalls that when he was a child, his father placed three sniff stickers on his bedside table every evening for him to smell and write down his impressions in a notebook when he woke up. This daily exercise, which he continues in his laboratory at the Fontaines Parfumées, has enabled him to be attentive to odors from an early age and develop a solid olfactory memory.
