A giant of the political left, Rosa Luxemburg is one of the foremost minds in the canon of revolutionary socialist thought. But she was much more than just a thinker. She made herself heard in a world inimical to the voices of strong-willed women. She overcame physical infirmity and the prejudice she faced as a Jew to become an active revolutionary whose philosophy enriched every corner of an incredibly productive and creative life--her many friendships, her sexual intimacies, and her love of science, nature and art.
