She briefly served as a nurse in World War II. Nazi occupation meant the fashion business in Paris was cut off for some years; Chanel's affair during World War II with a Nazi officer also resulted in some years of diminished popularity and an exile of sorts to Switzerland. In 1954 her comeback restored her to the first ranks of haute couture. Her natural, casual clothing including the Chanel suit once again caught the eye -- and purses -- of women. She introduced pea jackets and bell bottom pants for women. She was still working in 1971 when she died. Karl Lagerfeld has been chief designer of Chanel's fashion house since 1983.
