Well, to make a long story short, Marcel Proust was Jewish!
Since Marcel Proust's mother was Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father was not Jewish.
Marcel Proust (whose full birth name was Valentin Louis Georges Eugene Marcel Proust) was born on 10 July 1871 in Auteuil, France.
Marcel Proust was a French novelist, critic, and essayist best known for his monumental novel A la recherche du temps perdu (In Search of Lost Time; earlier translated as Remembrance of Things Past), published in seven parts between 1913 and 1927. He is considered by many to be one of the greatest authors of all time.
