Armin Haag was born in Sonneberg (Thuringia) and was a composer and conductor from Zielona Góra, formerly Grünberg (Silesia). He studied at the Academy of Music in Munich and after graduation worked as a conductor in Sighisoara in Transylvania until 1915. After World War I, during which Hass was wounded, he worked with the German symphony orchestra in Brussels, then from 1918 as a music teacher at high schools in Grünberg. Here he composed the play opera "Die gepanzerte Braut" (performed in Coburg on Feb. 5, 1922) as well as the opera "Der zerbrochene Krug" (premiered in Grünberg in 1925). It is thanks to his efforts that musical life in Grünberg could be rebuilt after the war. Here he appeared as a conductor of large concerts. He became known as a composer and lyricist of many festive songs. He also set to music the lyrics of well-known poets from Zielona Góra (Gruenberg), including Paul Petras, from whom the text of the "Schlesierlied'' originated. Many of Haag's melodies can be found in song collections, such as "Grünberger Wein- und Heimatlieder" (1929) and "Was man in Grünberg sang" (1929).
