It鈥檚 like a scene from one of Mozart鈥檚 operas 鈥� the master of the house snoops on his wayward maid and is shocked by what he learns.
The maid was Lisa Schwemmer, whom Mozart鈥檚 father, Leopold, had apparently told Mozart was in real need of a job. In a letter of December 1783, Mozart told Leopold that he and Constanze would take Schwemmer in if she wished to move to Vienna.
Schwemmer made the move. But in late May 1784, Mozart himself fomented a household drama. In a letter of May 26, 1784, Mozart wrote his father that Schwemmer had written the address on a letter to her mother in such a ridiculous way that the post would never had delivered it. He offered to address the letter correctly for Schwemmer. But, as he wrote his father, he ended up doing much more than that.
鈥淥ut of curiosity and with a view to reading some more of this amazing composition rather than with that of prying into her secrets,鈥� Mozart wrote, 鈥淚 broke the seal of the letter.鈥� (The Letters of Mozart and His Family, trans. Emily Anderson)
Mozart then wrote of Schwemmer鈥檚 litany of complaints about working in Mozart鈥檚 home. 鈥淪he complains that she gets to bed too late and has to get up too early 鈥� though I should have thought that one would get enough sleep between eleven and six, which is after all seven hours! [...] Then she complains about the food and that too in the most impertinent fashion. She says she has to starve 鈥︹€�
Not enough sleep, not enough food 鈥� Mozart reported that Schwemmer also griped about her pay. 鈥淎nd what has she to do? To clear the table, hand round the dishes and take them away and help my wife to dress and undress.鈥�
And Mozart had a few more unflattering things to say about Schwemmer. In the same letter to Leopold, Mozart called Schwemmer 鈥渢he clumsiest and stupidest creature in the world.鈥� He also recounted two drinking episodes between Schwemmer and 鈥渁 certain Herr Johannes,鈥� who, Mozart claimed, had come to their house when he and Constanza were not at home.
The first time, Mozart wrote, Schwemmer had 鈥渟willed so heavily that she couldn鈥檛 walk without support and the second time she was sick all over her bed.鈥�
Evidently Mozart鈥檚 indignation overrode any compunction he might have had about opening Schwemmer鈥檚 personal correspondence. So he leveled the boom, writing Leopold to ask Schwemmer鈥檚 mother to be looking for another job for her daughter. 鈥淲ere it not that I hate to make people unhappy I should get rid of her on the spot.鈥�
