Alexandre Du Sommerard returned to Paris in 1807 after spending time in the army in Italy. At this time he began work in an audit office in Paris. His interest in archaeology led to his position at the Louvre museum as a Sunday lecture guide. He was particularly interested in Medieval monuments and the time period of François I. His collection of mainly Medieval objects was housed in l'hôtel de Cluny. His son Edmond took over the building after his death in 1842 and on July 29, 1843, the collection became property of the French government. This was later to become the Musée de Cluny. Alexandre and Edmond co-authored a five volume work, Les arts du moyan age (Paris, 1838-1846).
