Scholar of Romanesque art. Deshoulières was part of the debate which took nationalistic overtones on the origin of the Romanesque. It had been launched by the American A. Kingsley Porter when he posited that pilgrimage and monastic reform explained the stylistic progress of the Romanesque, eminating not from France, but from Spain. The French academy rejected Porter's thesis in favor of their regional hierarchy. The attack was led by Paul Deschamps who published the most virulent corrections (Maxwell) to Porter's evidence. Dechamps was joined by Deshoulières, Charles Dangibeaud and Eugène Lefèvre-Pontalis who wrote essays attempting to defend the academy's classification.
