Adidas and Puma

German brother Adi and Rudolf Dassler founded their shoemaking firm in 1924. Twelve years later, Adi drove cross-country to Berlin, where he convinced Jesse Owens to wear his handmade running shoes in the Olympics. Owens won four gold medals, and the Dasslers’ white shoes became coveted by runners everywhere. But in 1948, after many years of feuding, the brothers split. Rudolph opened up a shop across the river and named his new enterprise Puma, while Adi renamed his company Adidas (the first three letters of his first and last names).
