Mozart is a controversial figure among his biographers, with the largest disagreements arising concerning his role as the parent of adult children. Mozart biographer Maynard Solomon has taken a particularly harsh view of Leopold, treating him as tyrannical,
mendacious, and possessive; Ruth Halliwell adopts a far more sympathetic view, portraying his correspondence as a sensible effort to guide the life of a grossly irresponsible Wolfgang.
Relations with Nannerl Wolfgang left home permanently in 1781 (see below), and from this time until 1784, his father lived in Salzburg with just Nannerl (now in her early 30s) and their servants. Nannerl had a number of suitors, of whom the most important was Franz Armand d'Ippold, with whom she was evidently in love. In the end she did not marry him, and the reason for this is unknown. One possibility, frequently entertained by biographers, is that the marriage was blocked by Leopold, who liked having Nannerl at home as the lady of the house. However, Halliwell observes that no written evidence on this point survives and insists that we simply do not know why Nannerl married so late. Nannerl finally did marry in August 1784, at age 33. She moved to the home of her new husband, Johann Baptist Franz von Berchtold zu Sonnenburg, in the small rural town of
St. Gilgen, roughly six hours journey east of Salzburg. During his remaining years, Mozart spent a fair amount of his time trying to help Nannerl at a distance, as her new marriage situation, involving five apparently ill-educated stepchildren, was apparently not easy. According to Halliwell, Nannerl depended on him in many ways: he did "shopping [and] the engagement of servants. ... He relayed news from Salzburg, Munich, and Vienna to divert her, did his best to organize the maintenance of her
fortepiano, paid for Wolfgang's music to be copied and arranged for her to receive it; collected musicians together when she had visited him so that she could play it with most of the parts; .. tried to look after her health; and encouraged her to stand up to her husband when he was being unreasonable." Following Leopold's death in 1787, Nannerl had to do without this support, and Halliwell asserts that "there is every reason to believe that Leopold's death was devastating" to her."
Raising Nannerl's child In July 1785, Nannerl came to Salzburg to give birth to her first child, a son. The infant stayed with his grandfather when she returned home, and with the assistance of his servants, he raised the child. He frequently sent letters to Nannerl (at least one per week) that usually began with the sentence "Leopoldl is healthy", ("Leopoldl" is "Little Leopold") and offered a full report on the child. Leopoldl stayed until his grandfather's death in May 1787. He apparently found raising his grandson a happy experience. Halliwell relates one repeated episode: Maynard Solomon suggests that in keeping his grandson in his home, Mozart may have hoped to train yet another musical prodigy. Halliwell notes a different possibility: that conditions for child-rearing in the Berchtold household were distinctly suboptimal.
Relations with Wolfgang Wolfgang left home for good in 1781, when instead of returning from a stay in Vienna with his employer
Archbishop Colloredo he remained in the city to pursue a freelance career. This effort was to a fair degree successful; Wolfgang achieved great fame and was for a time quite prosperous (though poor planning later changed this status). The move almost certainly aided Wolfgang's musical development; the great majority of his most celebrated works were composed in Vienna. As indicated by Mozart's return letters (which alone survive), his father was strongly opposed to the Vienna move, wanting Wolfgang to return to Salzburg. A fairly harsh family quarrel resulted. He was also strongly opposed to Wolfgang's marriage to
Constanze Weber in 1782, and gave his permission late, reluctantly, and under duress. Biographers differ on the extent that Constanze was later snubbed by Leopold, if at all, during her visit with Wolfgang (July – October 1783) to Salzburg; the
Grove Dictionary calls the visit "not entirely happy". In 1785, he visited Wolfgang and Constanze in Vienna, at a time when his son's career success was at its peak. He witnessed first hand his son's success as a performer, and on 12 February heard
Joseph Haydn's widely quoted words of praise, upon hearing the
string quartets Wolfgang dedicated to him, "Before God and as an honest man I tell you that your son is the greatest composer known to me either in person or by name: He has taste, and, furthermore, the most profound knowledge of composition." The visit was the last time that Leopold saw his son, though they continued to correspond, and Wolfgang sometimes sent copies of his piano concertos and string quartets for Leopold and Nannerl to perform with friends. Later in 1785, when Leopold Mozart took in Nannerl's child, Wolfgang was not informed. However, in the following year Wolfgang found this out from a mutual acquaintance in Vienna. At this time, Wolfgang wrote to Leopold to ask if he would be willing to take care of his own two children while he and Constanze went on concert tour. Leopold turned him down, probably with harsh words. His letter to Wolfgang does not survive, but his summary to Nannerl of it does (17 November 1786): For interpretations of this letter, see , which takes a viewpoint sympathetic to Leopold, and , which takes a viewpoint sympathetic to Wolfgang. Starting around the time he wrote this letter and continuing through the first part of 1787, his health was failing. He had become seriously ill by 4 April. On this day, Wolfgang wrote to him in alarm at the news, though he did not travel to Salzburg to see him. When Leopold Mozart died on 28 May (see below), Wolfgang was unable to attend the funeral since the travel time to Salzburg was too long. Little information is available on how Wolfgang took his father's death, but a postscript he included in a letter to his friend Gottfried von Jacquin suggests that, despite the quarrels and partial estrangement, his father's death was a blow to him: "I inform you that on returning home today I received the sad news of my most beloved father's death. You can imagine the state I am in." == Compositions ==
