Christine Nagel might just have the best job in the world. As the in-house perfumer for Hermès, she’s free to follow her impulses, unhampered by deadlines, market research, or focus groups. She also possesses a custom Birkin with pouches and pockets to hold all her perfume tools.

Nagel’s inspirations are wide and unexpected, from childhood memories to adult phobias. Her profound fear of horses posed certain challenges—given Hermès’s deep roots in the equestrian world—and spurred her to create several unlikely fragrances.
