Maria Anna Mozart, Austrian pianist (died 1829)

Maria Anna Walburga Ignatia "Marianne" Mozart, nicknamed Nannerl, was a highly regarded musician from Salzburg, Austria. In her childhood, she developed into an outstanding keyboard player under the tutelage of her father Leopold. She became a celebrated child prodigy and went on concert tours through much of Europe with her parents and her younger brother Wolfgang Amadeus Mozart. At age 17, her career as a touring musician came to an end, though she continued to work at home teaching piano and performing on occasion. At age 33 she married, moved to a village six hours by carriage from Salzburg, and there raised her own and her husband's children. On her widowhood in 1801, she returned to Salzburg and resumed teaching and performance. She is known to have composed works of music, though no manuscripts survive. In her later years she contributed to the biographical study of her late brother.
