Chanel Brooch Jewelry Maker. The House of Chanel (Chanel S.A.) originated in 1909 when Gabrielle Chanel opened a millinery shop at 160 Boulevard Malesherbes, the ground floor of the Parisian flat of the socialite and textile businessman Étienne Balsan, of whom she was the mistress. Because the Balsan flat also was a salon for the French hunting and sporting élite, Chanel had the opportunity to meet their demi-mondaine mistresses, who, as such, were women of fashion, upon whom the rich men displayed their wealth — as ornate clothes, jewelry, and hats.
