Herzogenaurach is a small town that is located in Bavaria, Germany. The nearest city is Nuremberg; roughly 14 miles away to the north west. The town is located on the Aurach river, which is a tributary of the river Regnitz. The town is famous for being the home of two sportswear companies: Adidas and Puma. The two companies were founded in 1948-1949 when the Dassler brothers (Adolf and Rudolf) fell out, dissolved their current sportswear business, and founded two new ones (Adolf (Adidas) and Rudolf (Puma)).
The two companies were located on either side of the Aurach river, and the majority of the population of Herzogenaurach were employed by one of the two companies. Due to the bitter rivalry of the brothers - who never spoke to one another - the town likewise had split loyalty, and would bend their necks to view what brand of footwear a person was wearing: Adidas or Puma. Therefore, the town became known as: "the town of bent necks".
The rivalry was at it's peak from the 1950's to the 1970's: when each company would compete against the other to poach the sponsorship of a sports star; such as Pele (who Puma poached after breaking a gentleman's agreement). When the brothers died in the 1970's so did the spark that fueled the rivalry. When production moved from Germany to the Far East (Vietnam etc) the rivalry within the population of Herzogenaurach dissipated as well.
