The woman: The youngest granddaughter of Prada founder Mario Prada, she and her husband, Patrizio Bertelli, took over the family-owned luxury goods manufacturer in 1978. Since then, they've turned it into a fashion powerhouse, acquiring Jil Sander, Helmut Lang and shoemaker Church & Co. The fortune: Family owns 100% of the privately held group, which posted revenues of $1.4 billion last year. An initial offering is expected later this year
