A more remote origin of the Institute can be found in the work done by a variety of French Vincentian historians beginning in the mid-nineteenth century after the Congregation of the Mission's post-revolutionary restoration. The fourteenth superior general, Jean-Baptiste Étienne (1801–1874), had a lively concern for the preservation of the "primitive spirit" of the Vincentians and Daughters of Charity. He and his successors commissioned a variety of materials including the "Annales de la Congrégation de la Mission", editions of selected letters of Vincent de Paul, editions of community documents, and a multi-volume history of the Congregation of the Mission. Confreres such as Gabriel Perboyre, Jean-Baptiste Pémartin, Félix Contassot, Jean Parrang, Fernand Combaluzier, Pierre Coste, and André Dodin are representatives of this French school of Vincentian historiography. Their labors established the foundation for all contemporary work in Vincentian studies.
