Aristide Cavaillé-Coll

Aristide Cavaillé-Coll was a French organ builder. He has the reputation of being the most distinguished organ builder of the 19th century. He pioneered innovations in the art and science of organ building that permeated throughout the profession and influenced the course of organ building, composing and improvising through the early 20th century. As the author of scientific journal articles about the organ construction details, he published the results of his research and experiments. He was the inventor of the symphonic organ being able to follow smooth and immediate dynamic changes like a symphonic orchestra. This goal was reached by: a) invention of harmonic flue and reed stops, such as the flûte harmonique, trompette harmonique, clairon harmonique, b) invention of divided windchest with 2-3 different wind pressure sections, c) creation of groups of stops allowing for fast dynamics changes without taking hands out of the keyboards by the organist, d) organ specification planning on the base of 'orchestral quartet". His most famous organs were built in Paris in Saint-Denis Basilica (1841), Église de la Madeleine, Sainte-Clotilde Basilica (1859), Saint-Sulpice church, Notre-Dame Cathedral, baron Albert de L'Espée's residence in Biarritz, and many others. After Cavaillé-Coll's death, Charles Mutin maintained the business into the beginning of the 20th century. The organ reform movement in the 20th century sought to return organ building to a more Baroque style; but since the 1980s, Cavaillé-Coll's designs have come back into fashion.
