Johann Rudolf Zumsteeg 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. Zumsteeg was bornborn in Sachsenflur, Lauda-Königshofen, and received his early education at the Carlschule in Stuttgart. There Zumsteeg became intimate friends with Friedrich Schiller. A setting for Schiller's drama, Die Räuber, 1782, is an example of the type of close collaboration that Zumsteeg undertook with prominent poets.
