Franziska Romana Koch, née Gieraneck, Giwraneck, Giraneck, Jiránek (1748–1796) was a German ballet dancer, soprano,[1] and actress.

Anton Schweitzer composed the opera Alceste for her, and its librettist Christoph Martin Wieland celebrated her performance in the title role in a poem.

Born in Dresden, the daughter of composer Antonín Jiránek,[2][3] Franziska made her debut as a ballet dancer in 1765 at the Kochische Gesellschaft, owned by Heinrich Gottfried Koch.

[4] Duchess Anna Amalia of Saxe-Weimar-Eisenach who disliked Koch, disapproved of the opera and forbade Wieland from continuing his dramatic poetry works.

[3] She was particularly successful in the operas of the conductor and composer Georg Benda, and performed in the premieres of his Romeo und Julie (1776) and Walder (1776).
