Chanel No. 5 is the first perfume launched by French couturier Gabrielle "Coco" Chanel in 1921. The scent formula for the fragrance was compounded by French-Russian chemist and perfumer Ernest Beaux. The design of its bottle has been an important part of the product's branding. Coco Chanel was the first face of the fragrance, appearing in the advertisement published by Harper's Bazaar in 1937.
