In the 1920s the two brothers Adolf and Rudolf Dassler start manufacturing sport shoes. Adolf is a talented craftsman and his dream is that one day all the best sportsmen in the world will wear his shoes. Rudolf on the other hand is the economical brain of their business, handling sales and marketing. After World War II, they continue producing shoes but the relationship between the two brothers starts to deteriorate. Both of them claim the company to be theirs, leading to an ever growing rivalry. A rivalry still existing today, represented by two of the most popular sports brands.—Wallwatcher
