Casavant Frères is a Canadian organ building company in Saint-Hyacinthe, Quebec, which has been building pipe organs since 1879. As of 2014, the company has produced more than 3,900 organs. Company history 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. Claver worked with Brodeur during 1874–1878, then went to France for a 14-month apprenticeship with the firm of John Abbey in Versailles. He and Samuel then visited many organs and workshops in western Europe before establishing their factory in 1879 on the site of their father's workshop on rue Girouard in Saint-Hyacinthe. Technical innovations Their instruments boasted many innovations unique for that time, such as concave pedalboards, balanced expression pedals, keyboard improvements, and other enhancements. Their reputation as organ builders of international status was cemented in 1891 with their construction of the organ for the Notre-Dame de Montréal Basilica, a four-manual organ of eighty-two stops. This organ features adjustable combinations and speaking pipes of thirty-two foot length in the façade. They won the Grand Prix at the International Exhibition held in Antwerp, Belgium, in 1930. They built organs around the world, including Canada, the United States, France, the West Indies, South and Central America, South Africa, and Japan. Their organs have been praised by many well-known organists over the last 100 years, including Guilmant, Vierne, Widor, Bonnet, Lemare, Dethier, Courboin, Bingham, and many others who inaugurated and played Casavant organs. Casavant organs are also found in colleges, universities and conservatories in the United States and Canada. After the death of the Casavant brothers, the company continued to add innovations to their instruments. These include a particularly reliable key contact and tracker touch mechanism, which is a feature of the Casavant playing action. During the 1960s, Casavant developed new electronic technology to the capture system of combination actions. In 1960, the company returned to mechanical action technology (while continuing to build electropneumatic action instruments as well) and has since built over two hundred tracker action instruments ranging in size from a single manual portable Continuo of four stops to two, three, and four manual organs. New technology, such as solid-state coupling and switching systems, multiplex, multi-memory combination actions and MIDI have been adopted. Other improvements, such as more effective expressive enclosures, continue to be made. The sound and style of Casavant organs has varied
