Feminism in Isak Dinesen's Writing

I've read a number of Isak Dinesen/Karen Blixen's works, and I am always struck by some of the feminist aspects/themes in her writing. It seems to me that she was ahead of her time. I would love to read an analysis of this. What are some feminist views she takes? How does this compare to society or the writings of other authors during the same time period? It could also be interesting to touch on her use of a male pseudonym and how this affects the perception of her works.
