The Maid of Orleans
In the Körner home Gottfried had built a small theater for family theatrical productions, which according to Siegel were good enough to attract professional theater people to the audience. Since Schiller was a close friend, this theater served as the venue for the (private) premieres of a number of his yet-unpublished plays; Siegel notes that Theodor Körner was the first to play the part of William Tell, and Stock herself was the first Joan of Arc (in The Maid of Orleans). Stock also served as "director, stage manager, and the children's coach."
