The first Chanel fragrance, Chanel No. 5, was launched in 1921, and like other early Chanel fragrances (Chanel no. 22, Bois des Iles, Gardenia and Cuir de Russie) was created by perfumer Ernest Beaux. Various apocryphal stories surround the creation of Chanel No. 5, including the well-known tale that the final formula was the result of an error on the part of Beaux's assistant, who mistakenly increased the intended amount of aldehydes. Regardless, No. 5 was a huge seller and became one of the world's best known perfumes.
