After his wife's death, the duke lived increasingly away from the court at Versailles, dividing his time between two of his many country residences, the Château de Rambouillet and the Château de Sceaux. He devoted the majority of the rest of his life to dispensing charity. During the French Revolution, he gave refuge in Sceaux to the poet Jean Pierre Claris de Florian, who had formerly been one of his pages and his secretary at the Château d'Anet and the Hôtel de Toulouse (seat of the Banque de France since 1811) in Paris.
