From 1809 to 1814, he was principal of the Viennese Theater an der Wien.

He wrote mostly librettos for Paul Wranitzky, Adalbert Gyrowetz and C. Weigl (Weisenhaus, The Orphanage), and translated many French operas into German.

In 1814, he revised the libretto of Fidelio at Ludwig van Beethoven's request.
