Horribly written, not like an encyclopedic article 

What is this drivel?

That Hüttenbrenner neither had the work performed, nor even let the society know he had the manuscript is curious and has spawned various theories. Was he given an incomplete score by Schubert and was waiting for the rest before saying anything? If so, he waited in vain throughout the six remaining years of Schubert's life. After Schubert's premature death in 1828 (of typhus as a complication of syphilis), why didn't Hüttenbrenner then make the existence of the manuscript known? Do the torn pages suggest he had somehow damaged the piece and managed to lose, or even inadvertently destroy, the last two movements?[5] Was guilt therefore the reason he kept silent about the work's existence for 37 years after Schubert died? Could personality factors like introvertedness or jealousy have been at play here?
