Maria Anna Walburga Ignatia "Marianne" Mozart (30 July 1751 – 29 October 1829), often nicknamed Nannerl, was a highly regarded musician from Salzburg, Austria. Already in her childhood, she established a remarkable reputation for herself across Europe as a child prodigy. However, her musical career was terminated by her parents, who forced her to stay in Salzburg and look for a future spouse. This did not stop her from utilizing her love and talent for music to teach the piano, as well as supposedly writing her own works.
