Alexandre Louis Philippe Marie Berthier, 4th Prince de Wagram (20 July 1883 – 30 May 1918) was a French nobleman and an art collector.
Born as the son of Alexandre Berthier, 3rd Prince of Wagram (1836–1911) and Baroness Bertha Clara von Rothschild (1862–1903),[1] a member of the German branch of the prominent Rothschild family, Alexandre Berthier grew up in 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.[1]
Alexandre Berthier was an active collector of modern art.[2] 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.[1]
Before leaving for the French Army and serving in World War I on 1 August 1914, Berthier bequeathed the Château de Grosbois to his sister. He served as an army captain and led a company of chasseurs during the Third Battle of the Aisne. He sustained fatal wounds from shell fire at Fort de Condé-sur-Aisne and died on 30 May 1918. He had no children.[1] [3] Berthier was buried at the Château de Grosbois, alongside his father and grandfather.[4]
