BORN 5 Jan 1762, Zell im Wisentaal, Baden-Württemberg - DIED 6 Mar 1842, Salzburg|
GRAVE LOCATION Salzburg: St. Sebastiansfriedhof
Daughter of Fridolin Weber, whose half-brother was the father of the composer Carl Maria von Weber. Their mother came from Mannheim and there Constanze and her sisters Aloisia and Sophie grew up. The girls were all good singers.
In 1777 the family was visited in Mannheim by Mozart and his mother and he fell in love with Aloisia, who rejected him. In 1779 the family moved to Vienna, but her father died there on 23 Oct. In Vienna Mozart stayed with the Webers until her mother found out that he courted Constanze, who was nineteen at the time. They married on 4 Aug 1782. They had six children, but only two survived. On 26 Aug 1783 she sang a soprano solo at the premiere of Mozarts "Mass in C Minor" that he had written for her.
When Mozart died in 1791 he left her nothing. But Constanze obtained a small pension from emperor Leopold II, organised concerts in memory of Mozart and managed to have his works published. In the mid 1790s she sang at concerts together with Aloisia and by this time Mozart's reputation was growing as fast as her financial security.
In 1797 the Danish diplomat Georg Nikolaus lived in the same house and from 1798 onwards they lived together. They married in 1809. From 1810 to 1820 they lived in Copenhagen. After travelling in Germany and Italy they settled in Salzburg in 1824. Nissen died in 1826. Both she and her husband had worked on a Mozart biography and Constanze published hers in 1828. During her last years her widowed sisters lived with her in Salzburg.
