[2] Brothers Joseph-Claver (1855–1933) and Samuel-Marie (1859–1929) got their start in organ building in the shop of their father, Joseph Casavant, under his successor Eusèbe Brodeur.
[4][5] Casavant's instruments boasted many innovations unique for that time, such as concave pedalboards, balanced expression pedals, keyboard improvements, and other enhancements.
[8] New technology, such as solid-state coupling and switching systems, multiplex, multi-memory combination actions and MIDI have been adopted.
Later tonal directors, Lawrence Phelps and Gerhard Brunzema, contributed styles from the German "Organ Reform Movement".
The most recent tonal directors, Jean-Louis Coignet and Jacquelin Rochette, are rooted in but not limited to the various French organ building traditions.
