Andrea Rita Dworkin (September 26, 1946 – April 9, 2005) was an American radical feminist activist and writer. She is best known for her analysis of pornography, although her feminist writings, beginning in 1974, span 40 years. They are found in a dozen solo works: nine books of non-fiction, two novels, and a collection of short stories. Another three volumes were co-written or co-edited with US Constitutional law professor and feminist activist, Catharine A. MacKinnon.
