[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.
[citation needed] Casavant organs are also found in colleges, universities and conservatories throughout the United States and Canada.
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.
