[1] Among other innovations Boisselot presented for the first time at the exhibition a mechanism by which individual notes and sounds were identified as Tonhalte or sostenuto pedal today.
The geographical location offered advantages: lower costs for workers, inexpensive availability of exotic woods over the harbor, easier access to export markets in Spain, Italy and in the French colonies.
[4] In 1865 Xavier handed over the management of the company to his nephew Franz Boisselot (1845-1908), the son of Louis Constantine, named after his godfather Liszt.
Franz led the Boisselot & Fils from 1893, when it was re-established as Manufacture Marseillaise de pianos until his death in 1908,[4] having the First World War brought the company to an end.
