Voltairine de Cleyre was an Anarchist thinker, lecturer, and writer. A contemporary of Emma Goldman's, she was known for her strength of will and commitment to the power of the individual. (Incidentally, she was also a total babe.)
I wanted to write about de Cleyre for the obvious reason that she was a totally brilliant early feminist, but also because while Goldman, her colleague and sometimes adversary, was and continues to be a hugely famous progressive hero, de Cleyre is a relatively obscure figure. This is partly because she died young and partly because she wasn't nearly as gregarious as Goldman, preferring to publish and fundraise in relative solitude. But! The work she did, though different than Goldman's, was just as important.
