Constanze, the wife of Wolfgang Amadé Mozart, was not the foolish and self-interested individual of popular opinion, much of which is based on the views of Mozart's father, who believed that his son had chosen an inappropriate partner. This strong-minded woman was, however, to be of critical support to her beloved husband. From a family of accomplished musicians, she was possessed of a fine voice and sang in public performances of a number of Mozart's works, both before and after his death. She bore him six children, of whom two survived childhood. Her business acumen was such that after his death she was largely responsible for keeping his music before the public, organising concerts, securing the accurate publication of many of his works, including the Requiem, and acquiring patronage from the aristocracy. Her second marriage to the Dane, Georg Nikolaus Nissen, continued a life story which is a rich example of self-sufficiency and competence in an era when a woman in business was a rarity. Importantly, this book restores the reputation of a woman much maligned by history.
