Inside an air-raid shelter in World War II Germany, another battle came to a head. Brothers Adolph – also known as Adi and Rudolf Dassler – had been working together for years, selling shoes and sporting equipment, but the relationship had deteriorated. The presence of Rudolf and his family elicited a snarky remark from Adolph when they entered the bunker, and later, Rudolf was picked up by the American forces, accused of being part of the Waffen SS. He was convinced this was Adolph’s doing, and when he was released, they split their company, Dassler Schuhfabrik, with Rudolf moving across the river. The two companies that were formed are leaders in the sportswear industry today – Adidas (ADI DASsler) and Puma (Changed from Ruda, which stood for RUdi DAssler).
