Abstract: In this contribution, I present a full-text edition of the original manuscript of Joseph Tanghe\'s 1930 article \'Le lingala, la langue du fleuve\'. An exhaustive bibliography of Tanghe\'s oeuvre is offered, as well as a comprehensive biography of this otherwise ill-known Belgian africanist of the colonial era. In this context, the influence the Minister of Colonies Louis Franck exerted on Tanghe\'s career and publications is discussed, as well as this minister\'s involvement in language matters in the Belgian Congo. Attention is also drawn to the debates around \'the linguistic question\' in the Belgian Congo. In 1944, Tanghe provided these debates with a new impetus.
