Physicists Hertha Sponer and Hedwig Kohn were two of only three women to meet pre-World War II Germany’s requirements to teach physics at the university level (the other being Lise Meitner). But in the 1930s, they were both removed from their teaching positions in Germany due to Antisemitism and misogyny. Years later, both Hertha Sponer and Hedwig Kohn ended up at Duke University. Hertha set up a spectroscopy lab there, and continued her research in quantum mechanics. After Hedwig Kohn’s retirement from Wellesley College, Hertha invited her to conduct research at Duke.
