In the summer of 1927, the international exhibition Music in the Life of Nations took place in Frankfurt am Main. Wilhelm Hermann Heckel received the honorary predicate of the Reich Association of German Musicians and Music Teachers for his artistic collaboration and practical presentation of the development of woodwind instruments. At that time, the honorary chairmanship of the association was led by Max von Schillings.
Wilhelm Hermann received the German Reichs-Honour Prize, the Golden State Medal, for the new instruments he exhibited. This was the highest accolade for musical instrument makers.
