How long has Tulane had a fairly large jewish population?

I was talking to a professor about this and it made me think to ask if anyone who's known the area for a long time would know. I've always found it interesting that Tulane while being non affiliated with any particular religion has seemed to have attracted a very large amount of Jewish students in one of the more Catholic dominated parts of the country for at least a few decades. What makes me ask is my professor himself is Jewish (and also probably in his 70s to help you figure out a timeline) told me that when his father applied to Medical School there he was denied because at that point they had quotas for Jewish students, indicated that they even used to discriminate against them.
