Bronsgeest is linked to the beginnings of radio at the beginning of the 20th century. He founded two major institutions, the Berliner Rundfunk Orchester (now the Rundfunk-SinfonieOrchester Berlin) and the Berliner Rundfunk Chor (now the Rundfunkchor Berlin). From 1924 to 1933, Bronsgeest was the Director of the Opera department of Berlin Radio. He created the concept of "ton meister" or "sound engineer" to provide the best possible audio quality. Radio opera performances were adapted by Bronsgeest to suit broadcasting requirements.
