Thierry Wasser: Carrying Guerlain Forward, from Field to Perfume Bottle

“In the world of perfumery, my relaxed attitude was what saved me.”

Thierry Wasser, from an interview with Luxury Tribune

Born on July 19, 1961, in Lausanne, Switzerland.

Safeguarding Guerlain’s perfumes involves more than writing formulas. It means visiting flower fields, speaking with growers, and checking how distillation is carried out. Wasser, the first person outside the founding family to be chosen as the house’s in-house perfumer, has taken on all of these responsibilities.

The “relaxed attitude” Wasser values does not mean taking the work lightly. It means trusting personal perception rather than overthinking in the presence of a scent. Part of what makes Wasser interesting is that someone with this freedom came to inherit such a long history.

A Life in Perfumery

Swiss Farms and the Habit Rouge That Protected a Boy

Wasser was born an only child at the Clémette maternity hospital in Lausanne. At the age of three, Wasser’s father left home, and Wasser grew up in Geneva, where the maternal grandparents of Italian descent lived. From 1970, Wasser lived with the remarried mother, Inès, in Chamby, near Montreux.

In Chamby, surrounded by forests and farmland, the boy spent much of the time on the neighboring farm. Seasonal harvests, animals, fruit, and the smell of soil: long before learning the names of perfumery materials, Wasser had absorbed the sight of plants growing and people working with them. Also fascinated by medicinal herbs, Wasser dried plants in the attic and made syrups, teas, and infused spirits.

Wasser also enjoyed rock climbing and skiing in the Alps. School life, however, did not go smoothly. Habit Rouge, encountered at thirteen, gave confidence to a boy who had been teased about body shape. Attracted by the fragrance worn by a friend of Wasser’s mother, Wasser began wearing it too. Perfume was like “armor,” protecting a still-unsettled sense of self.

Even after creating numerous perfumes, this remained the fragrance Wasser chose in private life. A creator’s tastes and a wearer’s memories live separately within Wasser.

From an Herbal Apprenticeship to Givaudan

Leaving school in 1976, Wasser began an apprenticeship with a druggist in La Tour-de-Peilz. This experience working with medicinal plants and herbal teas is described in later profiles as obtaining a qualification in botany. Rather than studying chemistry at university to become a perfumer, Wasser began with practical work involving plants.

Reading a magazine article about fragrance companies opened the next door. Intrigued, Wasser wrote to Givaudan and Firmenich and was invited to take an entrance test. Years later, Wasser recalled that period in an interview with LUXUO.

“I was nineteen and knew nothing. I took an olfactory test and was offered a place at the perfumery school. Before I knew it, I had fallen in love with that world.”

Serious training at Givaudan began in 1981. The school’s director, Jean Hadorn, was the person who discovered him. It was not just a question of knowing what a smell was, but of the words and emotions used to describe it. According to Wasser, the test valued the ability to put smells into words even when the material could not be identified.

Following school and practical training, Wasser became a junior perfumer at about twenty-four and moved to the fine-fragrance division in Paris in 1987. The resolve not to forget a debt to those who had chosen Wasser would later extend to relationships with growers and collaborators.

An Opposite Number Met in New York

In 1993, Wasser moved to Firmenich and went to New York. This was a period of testing skills acquired at Givaudan in a different market and creative environment.

Annick Ménardo was a frequent collaborator at the company. In a later interview, Wasser described theirs as a collaboration that worked because of their different personalities.

“She thought too much, and I did not think enough. She lacked the relaxed attitude needed to finish a perfume. I had it. We were a formidable duo.”

Thierry Wasser, from an interview with Luxury Tribune

One person thought everything through carefully; the other could take a decisive step forward at a certain point. Their combination produced such fragrances as Lancôme’s Hypnôse (2005), Diesel’s Fuel for Life for Her (2007), and Fendi’s Palazzo (2007).

Calvin Klein’s Truth (2000), meanwhile, was a collaboration with Jacques Cavallier Belletrud and Alberto Morillas. Wasser’s career includes many collaborations, but not every fragrance was made by the same group.

Wasser returned to Firmenich in Paris in 2002, the year Christian Dior’s Dior Addict was released. With its rich vanilla and pronounced white flowers, this fragrance became indispensable to any account of Wasser’s work before Guerlain.

Becoming Guerlain’s Fifth Perfumer

In 2007, Wasser worked with Sylvaine Delacourte, who was involved in fragrance development at Guerlain, and introduced Iris Ganache and Quand Vient La Pluie. The collaboration continued with Guerlain Homme (2008).

Then, in May 2008, the forty-six-year-old Wasser became Guerlain’s in-house perfumer. Wasser was the first successor chosen from outside the family since the house was founded in 1828, and its fifth “nose,” following Jean-Paul Guerlain.

The skills needed to create new fragrances were already there. At Guerlain, however, responsibility also extended to manufacturing and sourcing raw materials. For about two years after the appointment, Wasser learned this work while traveling with the predecessor.

A visit to Tunisia in 2009 proved particularly unforgettable. Jean-Paul, who was unwell, took the successor to an orange-blossom distillery of his that had long been unused.

“He sat on a chair in a corner of the garden, watching me look around to see what could be saved. Tears ran down his cheek. I will never forget that scene.”

Wasser subsequently resumed distilling neroli there. Each morning brought discussions with growers about flower prices and the arrival of the harvest. In the field, Wasser had inherited Guerlain’s work as a “perfumer-distiller,” the description once printed on its labels.

Perfume Has a Vocabulary, but No Grammar

Wasser sees perfume as an expression that touches emotions. In Luxury Tribune, Wasser explained the relationship between materials and creation through an analogy with language.

“Raw materials are words that you learn like a vocabulary. You tell stories with those words. But there is no grammar. So you have to combine the words until they make sense.”

Thierry Wasser, from an interview with Luxury Tribune

What matters is not adhering to fixed combinations, but what a scent makes its creator or another person feel. Morillas’s advice to stop thinking and try mixing colors reflects a similar attitude.

Of course, creating freely is not the same as being ignorant of tradition. At Guerlain, there is a continuity of scent known as the Guerlinade, centered on ingredients such as bergamot, rose, iris, jasmine, tonka bean, and vanilla. This does not mean that every fragrance has an identical formula; rather, materials and combinations carry the house’s identity forward.

Wasser has long favored rose, especially Bulgarian rose. In 2024, however, Wasser also spoke of an attraction to the contrasts of light and shade created by leather, bergamot, and vanilla. Rather than fixing a preference into a personal signature, Wasser chooses materials suited to what needs to be expressed at that moment.

Idylle: A Joyful Bouquet and 650 Trials

Idylle (2009) was the first major new fragrance after Wasser became the in-house perfumer. Centered on flowers including Bulgarian rose, it combined musk and a chypre outline to express a dream of love.

“For Idylle, I imagined a fresh, joyful bouquet that would symbolize love.”

Thierry Wasser, from remarks published by The Candy Perfume Boy

The fragrance communicates brightly, but the path to completion was not easy. In an interview with The Perfume Society, Wasser named Idylle as the fragrance that had required the most trials, putting the number at about 650.

Wasser also said that the usual Guerlinade had not been placed at the center of this fragrance. Being told within the company that it did not smell like Guerlain prompted a fresh consideration of what tradition meant. It was a fragrance that taught both how to show a new creator’s individuality and how to have the result accepted as a perfume of the house.

La Petite Robe Noire: Reaching a New Generation

The history of La Petite Robe Noire requires a distinction between the original fragrance and its worldwide release. Delphine Jelk created the original in 2009. Based on that fragrance, the 2012 version, in which Wasser was also involved, spread around the world.

Black cherry, almond, rose, black tea, vanilla, and tonka bean: beneath their approachable character lie a sweetness and shading characteristic of Guerlain. In a 2012 conversation, Wasser discussed creating a cherry impression by combining bitter almond with raspberry-type materials.

This success becomes more concrete when understood as collaborative work that included Jelk’s idea, rather than as Wasser’s invention alone. The two continued to collaborate on several subsequent fragrances.

Shalimar Parfum Initial: Exploring Inheritance through Scent

Shalimar Parfum Initial (2011) reconsidered, from a different angle, Shalimar, created by Jacques Guerlain in 1925.

The inspiration is described as a young niece’s request for a Shalimar of her own. Retaining materials connected to the original, including bergamot, iris, rose, tonka bean, and vanilla, Wasser gave it a lighter outline.

“To bring Shalimar into the present without compromising its character, changing it while preserving its magical appeal. To create the future while honoring the past. That was the challenge.”

Thierry Wasser, from remarks published on the perfume blog Geurengoeroe

Preserving the original as it is and creating a new fragrance from it are different jobs. Taking on that distinction is also part of what is expected of Guerlain’s perfumer.

Mon Guerlain: When Ingredients Begin to Speak

Mon Guerlain (2017), created with Jelk, centers on lavender, jasmine, sandalwood, and vanilla. For Wasser, lavender was not simply an ingredient to put in the top notes. Wasser has spoken of touching its small blue flowers and sensing humility, simplicity, and sincerity.

The order of creation matters when considering the connection with Angelina Jolie. In a 2018 interview with #legend, Wasser explained it as follows.

“When I began designing Mon Guerlain, Angelina Jolie was not yet there.”

Thierry Wasser, from an interview with #legend

The initial fragrance design came first, and Jolie then joined a collaboration that also encompassed the bottle and communications. Conversations with her reportedly led to a richer use of jasmine sambac in the subsequent floral version.

Seeing jasmine garlands used in India at weddings, in temples, and to welcome family members changed what the flower meant to Wasser. It became a material linked to love, joy, family, and wishes. Seeing raw materials where they are produced was not only a way to check quality, but also a way to gain experiences through which to speak about scent.

Returning to the Seventeenth Version of Encens Mythique d’Orient

An anecdote about Encens Mythique d’Orient (2012) illustrates the importance of working together. A member of Guerlain’s heritage team who had liked a trial later asked for another bottle, and Wasser provided a new trial with further improvements.

But the earlier scent was the one that person had liked. Wasser therefore went back through the trials and ultimately adopted the seventeenth formula. What a perfumer regards as an improvement may feel less appealing to others than an earlier version. Wasser describes the experience as demonstrating the value of listening to the people nearby.

Cologne du Parfumeur (2010) is also an important cologne for understanding the contours of Wasser’s fragrances. A bright work centered on neroli, it can be seen as connecting flower distillation with Guerlain’s history.

Protecting the Fields and the Perfumer’s Voice

Wasser has devoted about a third of each year to travel in search of raw materials: bergamot in Calabria, neroli in Tunisia, roses in Bulgaria and Grasse, lavender in Provence, ylang-ylang in the Comoros, and vanilla in Madagascar. The journeys also extend to Australian sandalwood, Indian jasmine, and Vietnamese oud.

Choosing raw materials involves not just how good they smell, but whether supplies can remain stable and whether the people producing them can continue their work. Seeing changes in the climate and poor harvests firsthand has intensified these concerns.

Wasser was appointed a Chevalier of the Légion d’honneur in 2014 and a Chevalier of the Ordre des Arts et des Lettres in 2020. In June 2025, Wasser became the fourth president of the Société internationale des parfumeurs-créateurs (SIPC).

In an interview that year, Wasser set out aims of protecting the diversity of creative materials, raising the cultural standing of perfume and its creators, and seeking regulation informed by actual use in the field. Criticism of regulation represents Wasser’s own position, but behind it lay a sense of urgency: if the work of fields and growers disappears, perfumery will lose forms of expression as well.

In Guerlain’s official profile as of 2026, Wasser is described as a master perfumer responsible for exploring rare natural ingredients and creating bespoke fragrances. Jelk, meanwhile, serves as director of fragrance creation. Having worked together for many years, the two continue to support the house’s fragrances as their roles evolve.

An Aside…

Music has been an important pleasure since childhood. An encounter with Tchaikovsky opened a listening world that expanded to Stravinsky, Prokofiev, Rachmaninoff, and others. In youth, Wasser also worked as an usher at the Montreux music festival, gaining opportunities to hear performances. It is characteristic of Wasser to say that, if not a perfumer, a conductor would have been the preferred career, then laugh that the job is so demanding it might not have been a good fit.

In painting, Wasser favors Mark Rothko. The experience of receiving emotion from color and surfaces also connects to thinking about the texture of a fragrance. In everyday life, Wasser enjoys walks with a dog and values the small pleasures of smell close at hand, such as noticing a popcorn-like scent on the pads of the dog’s paws.

Among admired fragrances, Wasser names Mitsouko (1919). A peach scent briefly emerges within a solemn chypre. Comparing it to the Mona Lisa’s enigmatic smile, Wasser describes it as a profoundly compelling perfume, even without wearing it personally.
