Who invited isn't clear in most accounts, but in most cases I expect it was a student group or an organized lecture series, probably more the latter because she got so many invites that she was very selective about where she appeared.

Most notably, her lead essay in The Virtue of Selfishness, "The Objectivist Ethics", was first delivered at an ethics symposium at the University of Wisconsin.
