The BBC has a story on the death of Marcel Marceau. You can read it here http://news.bbc.co.uk/2/hi/entertainment/7009040.stm
Well, Marcel, you should know was Jewish. Yes, he was one of the tribe. Family name was Mangel.
As the Wikipedia notes - and you'd think someone at the BBC knows all about Wiki - "At 15, his Jewish family was forced to flee their home when France entered the Second World War."
Why would the BBC hide his identity?
A mistake? Something overlooked? It's their policy not to mention religious/cultural/national identities?
Odd that, as my British friends would say.
