Hedwig Kohn

Hedwig Kohn (5 April 1887 – 26 November 1964) was a German-American physicist who was one of only three women to obtain habilitation (the qualification for university teaching) in physics in Germany before World War II. She was forced to leave Germany during the Nazi regime because she was Jewish. She continued her academic career in the United States, where she settled for the rest of her life.
