About Constanze Mozart

Maria Constanze Cäcilia Josepha Johanna Aloysia Mozart was an Austrian soprano, later a businesswoman. She is best remembered as the wife of the composer Wolfgang Amadeus Mozart, who from the evidence of his letters was deeply in love with her throughout their nine-year marriage. Following her husband's sudden death in 1791, Constanze Mozart escaped poverty and supported her family through concertizing and promotion of her husband's memory; she was responsible in part for the extensive posthumous publication of her husband's works. Constanze is also regarded, less positively, as a source of mythology concerning her husband's life, deriving in part from the biography she jointly wrote with her second husband, Georg Nikolaus von Nissen.
