Alexandre Louis Philippe Marie Berthier, 4th Prince of Wagram

Alexandre Louis Philippe Marie Berthier, 4th Prince de Wagram (20 July 1883 – 30 May 1918) was a French nobleman and an art collector.

Early life Born as the son of Alexandre Berthier, 3rd Prince of Wagram (1836–1911) and Baroness Bertha Clara von Rothschild (1862–1903), a member of the German branch of the prominent Rothschild family, Alexandre Berthier grew up at the family's ancestral home, the Château de Grosbois, a large estate in Boissy-Saint-Léger, southeast of Paris. He had two sisters, Elisabeth (1885–1960) and Marguerite (1887–1966), the latter of whom married Prince Jean Victor de Broglie. He owned works by prominent artists such as Alfred Sisley, Camille Pissarro, Claude Monet, and Pierre-Auguste Renoir. In his will, he bequeathed 17 of Renoir’s paintings to the French nation. Berthier was buried at the Château de Grosbois, alongside his father and grandfather.

Alexandre Berthier served as the model for a minor character in Marcel Proust's multi-part novel In Search of Lost Time. His mother is mentioned more frequently as Princess of Iéna.
