René Blum (13 March 1878 – September 1942) was a French Jewish theatrical impresario. He was the founder of the Ballet de l'Opéra at Monte Carlo and was the younger brother of the Socialist Prime Minister of France, Léon Blum. A Jew, he was interned in various camps from 1941 until he was murdered by the Nazis at the Auschwitz concentration camp in late September 1942. While at the camps, he was known for keeping up the spirits of his fellow prisoners with tales of his life in the arts.
