You can see the tombstone of Constanze Mozart, the wife of Wolfgang Amadeus Mozart, in the cemetery of the Sebastian Church. She died on March 6 1842. There is a very peculiar story described by Eric Weiner in his Geography of Genius related to Constanze and Mozart. On the night when Constanze was giving birth to their first child (17 June 1783), Mozart wrote the "Haydn Quartets". And that didn't happen before or after the labor but during! Mozart first summoned a midwife before sitting down at the piano. Constanze later confirmed that the quartet contained several passages that reflected her distress, especially the minuet. Unfortunately, the child only lived a couple of months and died on 19 August 1783.
