Anton Schindler
Beethoven is believed to have worked on this trio shortly before he left Bonn for Vienna in 1792. The precise circumstances of composition are not known and the work remained unpublished until after the composer died in 1827. When F. P. Dunst published the work in 1830, the publication included a statement to the effect that the work was Beethoven's, signed by Carl Czerny, Anton Diabelli and Ferdinand Ries. At that time the manuscript was stated to be held by Anton Schindler, but, according to Cooper it is now lost.
