Horst-Wessel-Lied
In 1936 a German music critic, Alfred Weidemann, published an article in which he identified the melody of a song composed in 1865 by the Weimar composer Peter Cornelius as the "Urmelodie" (source-melody). According to Weidemann, Cornelius described the tune as a "Viennese folk tune." This appeared to him to be the ultimate origin of the melody of the Horst-Wessel-Lied.
