Author of numerous accomplishments in Reims and Soissons before the First World War (including the completion of the church of Sainte Clotilde, the church of Saint Benoît, and the house of Jacques Simon) he participated actively in the reconstruction of Reims in the immediate post-war period.

[1] Born in 1870 in Péronne, Max Sainsaulieu trained in architecture with Edmond Duthoit, Inspector of Historic Monuments in Algeria,[1] before joining in 1891 the École Nationale Supérieure des Beaux-Arts in Paris.

In 1898, he received his architecture degree after a study on the restoration of the Fontenelle Abbey in Saint-Wandrille-Rançon.

In 1909 he returned to Reims to gradually resume the activities of his father-in-law Alphonse Gosset.

At the declaration of war, Sainsaulieu left Reims but returned after the First Battle of the Marne.
