Thierry Wasser
Thierry Wasser grew up Swiss, earned his Federal Diploma of Botany at twenty, and within four years had completed the Givaudan perfumery school and earned promotion to perfumer. He joined Firmenich in 1993, where he collaborated extensively with Annick Ménardo on dozens of fragrances including Dior Addict and Lancôme Hypnôse. LVMH named Wasser Guerlain's fifth in-house perfumer in 2008, making him the first outsider to lead the house founded in 1828. He divides his time between Paris and far-flung ingredient harvests, personally visiting farmers in Bulgaria, India, and beyond to source rose, vetiver, and vanilla for Guerlain's storied palette. Wasser succeeded Jean-Paul Guerlain himself, an appointment that signaled both continuity and generational change for a house that had never looked outside the family for creative leadership. He now oversees fragrance creation from raw material to final bottle.

How Thierry composes
Wasser gravitates toward green, crispy notes and the bold florals Guerlain is known for. Bulgarian rose appears repeatedly in his work, and he travels annually to oversee the harvest in Kazanlak. Vanilla holds equal affection in his palette. His Guerlain fragrances tend toward the ambery, vanilla-lavender register of Mon Guerlain and L'Homme Ideal, though his earlier work with Annick Ménardo at Firmenich showed versatility across woody-oriental and fresh-floral territory. He cites Guerlain Mitsouko as the fragrance he wishes he had created.
Philosophy
What drives Thierry
Wasser believes perfumery cannot be rushed. He allocates twelve to eighteen months per project, allowing formulations the time a stew needs to develop its spices. He has described his own nose as a tool he can consciously switch off, insisting that creation happens in the brain rather than the nostrils. For Wasser, the perfumer's responsibility extends beyond the laboratory to the farmers and harvests that supply ingredients, relationships he considers precious and central to Guerlain's identity. He speaks of emotional perfumery, of creating scents that resonate beyond their materials, and of embracing freedom within the house's century-old traditions.
