Born OTD in 1871, Polish Marxist, philosopher, economist, anti-war activist & revolutionary socialist, Rosa Luxemberg. A giant of the political left, 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 & the prejudice she faced as a Jew to become an active revolutionary whose philosophy enriched every corner of an incredibly productive & creative life—her many friendships, her sexual intimacies, & her love of science, nature and art.
