|Beethoven's Funeral as painted by Franz Stöber (notice the trombones in the front of the procession)|
|Jean Francois Bellon|
Below is Bellon's biography from From Classical Plus:
Jean-François Bellon was a Paris-based violinist and composer. As a result of the Waterloo War in 1815, his training at the Paris Conservatoire was delayed, so it was at the advanced age of 28 that he won the violin prize there. While at the Conservatoire he also composed pieces for fellow students.
Bellon went on to play in many popular Paris orchestras of his day, and was also the inventor of a type of mute for the violin and cello, which he patented, and examples of which are still kept in the Paris Conservatoire Museum. He became the leader of the Musard Orchestra in Paris and it was probably drawing on the brass section of this orchestra that he was able to form an ensemble to perform his Quintets.
