Christoph von Wilhelm Dassler was a worker in a shoe factory, while his wife Pauline ran a small laundry in the Bavarian town of Herzogenaurach, 20 km (12.4 mi) from the city of Nuremberg. After leaving school, their son, Rudolf Dassler, joined his father at the shoe factory. When he returned from fighting in World War I, Rudolf received a management position at a porcelain factory, and later in a leather wholesale business in Nuremberg.
Rudolf returned to Herzogenaurach in 1924 to join his younger brother, Adolf, nicknamed "Adi", who had founded his own shoe factory. They named the new business "Gebrüder Dassler Schuhfabrik" (Dassler Brothers Shoe Factory). The pair started their venture in their mother's laundry. At the time, electricity supplies in the town were unreliable, and the brothers sometimes had to use pedal power from a stationary bicycle to run their equipment.[5]
Adolf drove from Bavaria to the 1936 Summer Olympics in Berlin with a suitcase full of spikes and persuaded United States sprinter Jesse Owens to use them, the first sponsorship for an African American. Owens won four gold medals. Business boomed; the Dasslers were selling 200,000 pairs of shoes annually before World War II.[6]
