Altonaer FC von 1893
"Altona" is one of Germany's oldest football clubs: they were part of the Altona-Hamburg football league formed in 1894, as well as one of the founding clubs of the German Football Association (Deutscher Fussball Bund or German Football Association) at Leipzig in 1900. In 1903 at their home ground, they hosted the first-ever German national championship final played between "VfB Leipzig" and "DFC Prague". The match was refereed by "AFC" player Franz Behr, who also served as the vice-chairman of the newly formed DFB until 1904. The club rescued the match by providing a new ball when the original one proved to be unsuitable for play. The hosts of the country's first title match never won or even played in a national final, being able to advance only as far as the semi-finals in 1903 and 1909, and the quarter-finals in 1914.

It was joined by "Fussball Club Union Dortmund" in 1910 and on 13 July 1913 merged with "Ballspielverein 1904 Dortmund" to become "Sportvereinigung Dortmund 1895" before first adopting the name "Dortmunder Sport Club 1895" in 1919. This combined side made an appearance in the top flight regional playoff round in 1920–21.
