He hit headlines as a result of the disaster at the 2010 Love Parade in Duisburg, which he organized. On 21 October 2022, Schaller and his son Aaron died in a private plane crash in Costa Rica. Early life Schaller grew up in Schlüsselfeld, West Germany near Bamberg. His mother and grandfather worked in retail there. The conductor and Anton Bruckner expert, Gerd Schaller, is his brother. Business career Retail Schaller completed his training as a retail salesman in Schlüsselfeld. He supplemented this with further training to become a business and retail specialist. At the age of 22, he took over his first Edeka supermarket, and shortly afterwards three more in his home region. Fitness industry In 1997, he switched to the fitness industry and opened his first studio under the McFit brand in Würzburg, Germany. He tapped into the discount segment of the market with this brand. By mid-2006, McFit was operating 62 fitness studios in Germany with a combined 400,000 members and 1,000 permanent employees.
