BFC Germania 1888
BFC Germania 1888 was founded by 17-year-old Paul Jestram, his three brothers, and a number of their schoolmates from Askanischen Gymnasium at a time when football was not yet common in Germany, the first football games having been played in Berlin and Hamburg in the winter of 1881–82 by expatriate Englishmen. No football pitches had yet been built so "BFC" played on the Tempelhofer field where an airport would later be constructed.
Sportfreunde Siegen
The club was founded in 1899 as the football department of a gymnastics club called "Turnverein Jahn von 1879 Siegen", being one of the first clubs in Western Germany to offer organized football to its members. In 1923, it merged with "Sportverein 07 Siegen" to become an independent football club called "Sportfreunde Siegen von 1899".
