This source is a letter published by the sports club “Schild” run by the Hamburg chapter of the German-Jewish War Veterans’ Association Vaterländischer Bund jüdischer Frontsoldaten e. V.. It appeals to all male and female Jewish athletes to join the newly founded sports club “Schild.” Although sports clubs named “Schild” and linked to the Reich Association of Jewish War Veterans  Reichsbund jüdischer Frontsoldaten (RjF), the umbrella organization of the German-Jewish War Veterans’ Association  Vaterländischer Bund, had been founded as early as 1925, there was no local chapter in Hamburg. Following the introduction of the “Aryan articles”  Arierparagrafen and the resulting exclusion of Jewish athletes from sports clubs previously open to anyone, the Hamburg chapter of the Bund considered it imperative in June 1933 to establish a sports club. The letter was signed by the club’s provisional board consisting of ten persons. Among them was at least one prominent athlete, boxer Felix Friedemann. The original of the letter is kept at the State Archive Hamburg  StaHH 522-1_1083 05.
