Wrote at least some brief articles for the Neue Zeitschrift für Musik as well (e.g. reporting on concerts in Brno/Brunn in 1922, p.177. Elsewhere it is mentioned that Peterka has become a conductor, also in Brno/Brunn, of the Deutsch-Akademischen Philharmonie an der hiesigen Deutschen Technischen Hochschule, the same year.)
