The extraordinary true story of four women pioneers in physics during World War II and their daring escape out of Nazi Germany

In the 1930s, Germany was a hotbed of scientific thought. But after the Nazis took power, Jewish and female citizens were forced out of their academic positions. Hedwig Kohn, Lise Meitner, Hertha Sponer and Hildegard Stücklen were eminent in their fields, but they had no choice but to flee due to their Jewish ancestry or anti-Nazi sentiments.

Their harrowing journey out of Germany became a life-and-death situation that required Herculean efforts of friends and other prominent scientists. Lise fled to Sweden, where she made a groundbreaking discovery in nuclear physics, and the others fled to the United States, where they brought advanced physics to American universities. No matter their destination, each woman revolutionized the field of physics when all odds were stacked against them, galvanizing young women to do the same.

Well researched and written with cinematic prose, Sisters in Science brings these trailblazing women to life and shows us how sisterhood and scientific curiosity can transcend borders and persist--flourish, even--in the face of seemingly insurmountable odds.
