Antoine Courtois’ father creates the first family-run worship for manufacturing instruments during the french revolution in Paris rue Mazarine. Located in what is know how as the Latin quarter of Saint-Germain-des-Prés. A natural horn exhibited in Berlin and a cavalery trumpet in the museum of Paris conservatory bear witness by their engravings to this early period. The trumpet was once the property of the parliamentary officer sent by Napoleon Bonaparte to the siege of St John d’Acre in 1799.
Antoine Courtois (1770-1855) moves his workshops to 21 rue du Caire. Included among his instruments of this era , semi circular trumpets sounding similar to the horn, slide trombones, flugelhorns with keys, horns and few ophicleides were found.
On the 21st of February 1851, Denis A. Courtois’ son and successor of Antoine Courtois in 1844, patents his invention at the Seine Department Prefecture for improvements in the manufacturing of brass instruments and in particular for making valves.
Denis A. Courtois moves the manufacturing plant to 88 rue du Marais, where he works on improving instruments in partnership with renowned artists such as Jean-Baptiste Arban, a collaboration that would bring us the Arban valve.
