Written in the form of a police investigation, this article examines a claim made by the first biographer of Mgr. de Laval (1623–1708) that a clergyman, whose name he did not mention, made wooden organs for churches in Quebec City and its surroundings. The author of this article formulates here a research hypothesis on the identity and life of this first Canadian organ maker based on several clues discovered in archives relating to the New France era. Ultimately, this article is a reflection on the cultural context that prevailed in Quebec City at the turn of the 18th century and an invitation to researchers to pursue this investigation, which reopens the debate on the genesis of organ making in Canada.
