Puma SE is a German multinational corporation that designs and manufactures athletic and casual footwear, apparel and accessories, headquartered in Herzogenaurach, Bavaria, Germany. Puma is the third largest sportswear manufacturer in the world. The company was founded in 1948 by Rudolf Dassler (1898–1974). In 1924, Rudolf and his brother Adolf "Adi" Dassler had jointly formed the company Gebrüder Dassler Schuhfabrik ('Dassler Brothers Shoe Factory'). The relationship between the two brothers deteriorated until they agreed to split in 1948, forming two separate entities, Adidas and Puma. Following the split, Rudolf originally registered the newly established company as Ruda (derived from Rudolf Dassler, as Adidas was based on Adi Dassler), but later changed the name to Puma. Puma's earliest logo consisted of a square and beast jumping through a D, which was registered, along with the company's name, in 1948. Puma's shoe and clothing designs feature the Puma logo and the distinctive "Formstrip" which was introduced in 1958. Christoph Dassler was a worker in a shoe factory, while his wife Pauline ran a small laundry in the Franconian town of Herzogenaurach, 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 was trained as a salesman at a porcelain factory, and later in a leather trading business in Nuremberg. In 1924, Rudolf and his younger brother, Adolf, nicknamed "Adi", founded a shoe factory. They named the new business "Gebrüder Dassler Schuhfabrik" (Dassler Brothers Shoe Factory) which was the only business at the time that manufactured sports shoes. 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. In 1927, they moved into a separate building.
