Hofrat is quite correct about JM Kraus. One could also point to the scandalous case of Franz Xaver Pokorny,who at Regensburg had nearly 100 works attributed to him in the score but the same works attributed to other composers in the performance parts ! The 'Pokorny Case' is rarely discussed (being dangerous to the 'Wiener Klassik') But the same could be said of Sammartini who, early in Haydn's career was submitting sometimes 2 symphonies a month to Esterhazy and who was in huge demand. (One collector in the 1780's had around 1,000 works by this composer alone).
In the early 1780's a Haydn enthusiast at Bonn is said to have owned no less than 80 Haydn symphonies at that time ! These now vanished of course.
It was Leopold Mozart who, as late as the early 1780's was discouraging Wolfgang from performing any of Wolfgang's own symphonies at that time - so low did he himself estimate them.
In the Borde's multi volume work published in Paris in the early 1780's on contemporary music we find listed as a famous symphony writer in big demand amongst German princes a certain Herr Andrea Luchesi. We do not, however, find there either Haydn or Mozart listed as writers of symphonies.
Could this have a bearing on the fateful words written by Constanze Mozart which appear in the Nissen biography of Mozart -
'We do not want and we must not publicly show our hero, as he maybe would have described himself in the intimacy of domestic evenings. To say all the truth might do harm to his fame, to his respectability, to the success of his very music'.
