Hair entrepreneur Antoine de Paris (Antoni Cierplikowski, (1884-1976) ran 67 salons from Europe to Hollywood. He created the bob, as well as the perm, hair lacquer, blonde streaks and blue tints. He gave Claudette Colbert her famed bangs, the Duchess of Windsor her ‘Italian Madonna’ look, Greta Garbo her long bob, and Mary Martin washed that man right out of his cut in “South Pacific.”

In 1938, a famous American hold-out submitted to Antoine's shears: Eleanor Roosevelt.
