The Vincentiana Collection of the Archives and Special Collections Department of DePaul University has acquired a carte-de-visite of Jean-Baptiste Etienne (1801-1874) the 14th superior general of the Congregation of the Mission and the Company of the Daughters of Charity. The image shows an elderly Etienne. It is estimated to have bee taken c. 1870 when Monsieur Etienne celebrated the 50th anniversary of his entrance into the Congregation. Cartes-de-visite were tremendously popular in mid to late 19th century France, and photography studios sprung up throughout Paris and the rest of France.

The photographer August Coudret had his studio on the boulevard Saint-Jacques. He began his professional work in 1867, thus supporting the dating of this photograph as c. 1870.
