Victor Charles Paul Dourlen (3 November 1780 – 8 January 1864) was a French composer and music teacher at the Conservatoire de Paris during the first half of the nineteenth century. He is primarily known as a theorist on account of his treatises on harmony, based on the methods of Charles Simon Catel,[1] which were widely used as reference works, especially his Traité d'harmonie (c. 1838), the Traité d'accompagnement pratique (c. 1840), and his Méthode élémentaire pour le pianoforte (c. 1820).
