Watermarks is the story of the champion women swimmers of the legendary Jewish sports club, Hakoah Vienna. Hakoah ("The Strength" in Hebrew) was founded in 1909 in response to the notorious Aryan Paragraph, which forbade Austrian sports clubs from accepting Jewish athletes. Its founders were eager to popularize sport among a community renowned for such great minds as Freud, Mahler and Zweig, but traditionally alien to physical recreation. Hakoah rapidly grew into one of Europe's biggest athletic clubs, while achieving astonishing success in many diverse sports. In the 1930s Hakoah's best-known triumphs came from its women swimmers, who dominated national competitions in Austria. After the Anschluss, the political unification of Nazi Germany and Austria in 1938, the Nazis shut down the club, but the swimmers managed to flee the country before the war broke out, thanks to an escape operation organized by Hakoah's functionaries.
