Adolf Dassler

Verified Timeline

Lore & Background

Adi Dassler began his business by repairing shoes in town, scavenging army debris such as helmets and bread pouches for leather and parachute silk for slippers. He rigged a leather milling machine to a stationary bicycle powered by the firm's first employee to mechanize production without electricity. He produced one of the earliest spiked shoes, with spikes forged by the smithy of his friend Fritz Zehlein, and experimented with materials like shark skin and kangaroo leather. His widow later said, "Developing shoes was his hobby, not his job. He did it very scientifically."

In 1924, Rudolf joined the firm, and they registered Gebrüder Dassler, Sportschuhfabrik, Herzogenaurach on 1 July 1924. By 1925, they made leather football boots with nailed studs and track shoes with hand-forged spikes. Former Olympian Josef Waitzer became a consultant, giving Adi access to athletes at the 1936 Berlin Olympics. At the 1928 Amsterdam Games, Lina Radke won gold wearing Dassler track shoes. At the 1936 Berlin Olympics, Jesse Owens wore Dassler shoes with two leather strips on the sides and dark spikes when he defeated Luz Long in the long jump, and in his two further individual gold-winning performances in track and as a member of the United States' relay team. Both brothers joined the Nazi Party on 1 May 1933, three months after Hitler became Chancellor. During the war, the firm was partially converted to military production. By October 1942, Adi requested the use of five Soviet prisoners of war to man his production line. Wartime conditions worsened the feud between the brothers, with Rudolf blaming Adi's wife Käthe for the rift. After the war, the brothers separated and started their respective companies in 1948.
