F ranziska Wuerbser is a German billionaire heiress to the fortune of her late grandfather, Willy Bogner Sr., and father, Willy Bogner Jr., who built the Bogner brand into an international icon of luxury skiwear and sportswear. The company was founded by her grandfather, a German Nordic skier, in 1932. Her father, Willy Bogner Jr., a former Olympic skier and filmmaker, took over and transformed the brand into a global symbol of high-fashion sportswear, famous for its innovative designs.

Upon her father's retirement, the family's ownership of the privately held company passed to the next generation. Franziska, along with other family members, inherited a significant stake in the iconic German brand. Her wealth is derived from her ownership of this long-standing and prestigious family-controlled fashion enterprise.
