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. 
Concurrently, Bronsgeest founded in 1922 Deutsche Gast–Opera in the Netherlands, spending two years commuting between Berlin and The Hague. He led this flying Opera Society, staging singers including Anton Sistermans, Gemma Bellincioni, Emmy Bettendorf, Leo Schutzendorf, Frida Leider and Louis Morrison.
In 1933, Bronsgeest was forced by the Nazi regime to give up his position at Berlin Radio. However he continued to perform and direct the Berliner Theater der Jugend from 1935 to 1944. He provided opera performances with a small Opera troupe for German soldiers during World War II. He directed Berlin's first postwar Opera performance on August 12, 1945 (Rossini’s Barber of Seville), singing the Role of Count Almaviva. The performance was staged as a chamber opera and performed before a full house, with representatives from the American military government, Critic Christian Wrickert wrote, "the attempt was an adventure, but the success justified Bronsgeest."
