He was born in Vienna, where he studied the flute at the Vienna Conservatory. While holding various conducting posts in the city, he began to compose operettas. The first was Der tote Gast, an operetta in one act, premiered in 1865 with libretto by Ludwig Harisch, after the novel by Heinrich Zschokke.
The international success of Der Bettelstudent enabled him to retire from conducting. However, he never achieved a comparable success afterward.
