Siegfried Kapper was the literary pseudonym of Isaac Salomon Kapper (21 March 1821, Smíchov – 7 June 1879, Prague), a Bohemian-born Austrian writer of Jewish origin. Born in Smichow, Kapper studied medicine at Prague University, later completing a Ph.D. at the University of Vienna. Kapper wrote excellent fairy tales and poems, and was one of the leading figures of Czech-Jewish assimilation. Kapper wrote in both German and Czech. He translated Mácha's Máj into German for the first time (1844). Austrian composer Nina Stollewerk used Kapper's text for her composition "Zwei Gedichte," opus 5.
After his death, the Kapper-Society was founded; its aim was Czech-Jewish assimilation and opposition to Zionism and German-Jewish assimilation.
