Etienne Balsan was a French heir and socialite who was born into a family of wealthy industrialists. Coco Chanel was his mistress. It appears that he died in 1953 at age 75 of natural causes.
Gabrielle "Coco" Chanel was never in love with Etienne Balsan. She was in love with Arthur "Boy" (sorry I don't know his last name). But to answer when she met Etienne Balsan, it was in 1923 in Monaco.
Etienne Balsan and Coco Chanel ended their relationship long before his death, so I doubt that it is recorded. He died in 1953. They still remained friends throughout their lives.
Coco Chanel had several lovers throughout her life, including Etienne Balsan, Arthur "Boy" Capel, and the Duke of Westminster, Hugh Richard Arthur Grosvenor. These relationships greatly influenced her personal life and career in fashion.
