The perfumer dips a tester into one of the tiny glass vials aligned on the desk in front of him. There are dozens of them, with labels identifying various dilutions of compounds such as methyl geranate, phenyl acetate, and akigalawood. He brings the paper to his nose and inhales.

“Once in a while, I try to introduce my palette to new ingredients, to see if they’re interesting enough to create something with,” Francis Kurkdjian says. “Most of the time, they’re not.” With that, he tosses the strip into the trash.

To be a perfumer is to be a lifelong learner. Science advances, ingredients run out, regulations governing what you can use (or can’t) change. But Kurkdjian’s high standards and boundless curiosity have helped the 55-year-old become one of the industry’s best-known and most prolific noses, as those in the profession are often called.

Since 2021, he has been Dior’s perfume creation director; before that, he cofounded his own house, , and spent more than 25 years helping other companies articulate their olfactive identities. His hundreds of commissions—Jean-Paul Gaultier’s Le Male, Kenzo World, and Carven Pour Homme among them—have generated many millions of dollars for luxury’s leading lifestyle companies. Along the way, his increasing renown has helped bring perfumers from behind the scenes and into the spotlight.

“It’s a profitable business when you make a name for yourself, without a doubt,” says Robert Burke, CEO of luxury consultan.
