In the 1950s, self-made businesswoman Brownie Wise transformed the fortunes of Tupperware by inspiring thousands of housewives to sell it at parties.
Her methods for motivating staff included selling the dress off her back and holding annual parties at the company's headquarters.
But as she became a star - appearing on magazine covers and chat shows - Brownie's relationship with her boss, Earl Tupper, soured.
Author Bob Kealing speaks to Vicky Farncombe about Brownie's rise and fall from grace.
