Well, to make a long story short, Marcel Marceau was Jewish!
Since Marcel Marceau'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 Jewish too.
Marcel Marceau (whose full birth name was Marcel Mangel) was born on 22 March 1923 in Strasbourg, France.
He was an internationally acclaimed French actor and mime most famous for his stage persona as ''Bip the Clown.''
