"If anything, the article probably understates her importance ..."
In the second paragraph of the first page the author subtly suggests that she is the greatest mathematician as well as the greatest physcicist (at least a bunch of her contemporaries, who are smarter than you, the reader, thought so).
Also, in my personal experience, she is quite well known.
I would add to your list of her accomplishments: I've been told that she was one of the first to push for Homology to be treated as groups and not simply just betti numbers.
