Johann Rudolf Zumsteeg (10 January 1760 – 27 January 1802) was a German composer and conductor. Zumsteeg championed the operas of Mozart in Stuttgart, staging the first performances there of Die Zauberflöte, Don Giovanni, and Cosi fan tutte. He also was a prolific composer of lieder and ballads. His ballads had a great influence on the young Franz Schubert, who imitated a number of Zumsteeg's as studies (some even in exactly the same keys) while he was a teenager.
