Dorot professor?

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.

It is likely that the Dorot Foundation has endowed her position at Emory. Endowing a professorship (often then called a "named chair"), is a common way to contribute to a university. See "https://www.dorot.org/ Dorot Foundation: Charitable family foundation. Includes information about grants for student travel to Israel and other purposes." I would assume that the Dorot Foundation likes her work and wants to support it. See other answer for confirmation. When you see a faculty member identified, e.g., as "The John and Mary Smith Professor of XXX," it's likely a chair endowed by the Smiths.
