I encountered the term in a passage from an article in BBC History Magazine:
In her book Denying the Holocaust: The Growing Assault on Truth and Memory, published in the UK in 1994, Lipstadt (now the Dorot professor of modern Jewish and Holocaust studies at Emory University in the US) had called Irving a Holocaust denier and a falsifier of history.
I've searched a bit, finding that a few others have this title. but couldn't find the meaning of it. I kind of have a feeling that it is something to do with her being a Jew after I compared the English and Chinese versions of her entry on Wikipedia, but can't be sure. Anyone knows what it is? Thanks.
