S ophie Luise Fielmann is a German heiress whose wealth is derived from her significant stake in Fielmann AG, Europe's largest optical retail chain. She is the daughter of the company's late founder, Günther Fielmann, a visionary entrepreneur who revolutionized the German eyewear market. In the 1970s, he broke the grip of expensive optometrists by offering fashionable glasses at affordable, transparent prices, a model that proved immensely popular and allowed him to build a retail empire with hundreds of stores across Europe.

Upon her father's death in 2024, his vast fortune, centered on the family's controlling stake in the publicly traded company, was passed down to his two children, Sophie and her older brother, Marc. While her brother Marc has taken over the active leadership of the company as its CEO, Sophie is not involved in the day-to-day management. Her billion-dollar fortune is based on her inherited ownership stake in the iconic and highly successful family-controlled retail business.
