In November 1322, Jakoba (or Jacoba) Felicie stood trial in her native Paris for the crime of practicing medicine without official sanction. Over the course of the trial, it became clear that her work as a doctor had been excellent. But Dr. Felicie was stuck in an unfortunate catch-22. She could not legally work as a doctor without first getting professional training. And she could not get professional training because she was a woman. The ScienceZest blog tells her story.
