In 1921, Gabrielle Chanel asked Ernest Beaux to create "a woman's perfume with a woman's scent", rare and powerful. The nose presented her with a visionary composition that made unprecedented use of aldehydes. Mademoiselle chose the fifth sample of the fragrance, and decided to name it simply N°5. For this new fragrance, she opted for a bottle with a radical design, adorned with a white label and topped with a faceted cabochon. The unprecedented scent of the fragrance, along with its simple name and bottle, revolutionised the history of perfumery. N°5 has become a true cult fragrance.
