Albert-Ernest Carrier-Belleuse (1824-1887) made this bust around 1863. It was made in several examplaires, of which at least one is in bronze.

Carrier-Belleuse, with whom Rodin worked in Belgium, made copies of his own works at workshops, excluding those in bronze.

Only one of these busts of Beethoven can be found in a public collection, in the museum of Ermitage at Saint-Petersburg...

Thanks to Laure de Margerie, from the Musée d'Orsay
who replied with clairty and kindness to my requests for research...

A small Beethoven sculpture at Montevideo.

It would seem that this was either crafted by Antoine Bourdelle, or inspired in his style (notably Beethoven with Big Hair)...

If you know more any details would be most welcome, thank you.
