Nannerl Mozart Square Sticker

Anonymous portrait, 18th c. Maria Anna Walburga Ignatia Mozart (30 July 1751 – 29 October 1829), called "Marianne" and nicknamed Nannerl, was a musician, the older sister of Wolfgang Amadeus Mozart (1756–1791) and daughter of Leopold (1719–1787) and Anna Maria Mozart (1720–1778). There is evidence that Marianne wrote musical compositions, as there are letters from Wolfgang praising her work. When Wolfgang was a toddler, Nannerl (four and a half years older) was his idol. According to Maynard Solomon, "at three, Mozart was inspired to study music by observing his father's instruction of Marianne; he wanted to be like her." The two children were very close, and they invented a secret language and an imaginary "Kingdom of Back" of which they were king and queen.
