Tikkun Olam: To Repair the World explores the overwhelming contribution of Jewish artists to the creation of Modernism andsubsequently to Post-modern practices into the 21st century. The paper is predicated on the theory that Jewish artists, either secular or otherwise, entering post-war arts culture at mid-century, brought with them a deeply embodied commitment to tikkun olam. Tikkun olam is an aspect of Tzedakah, derived from the Hebrew root Tzade-Dalet-Qof, meaning righteousness, justice, or fairness. Engaging in acts of tikkun olam is a primary means of satisfying the need to create a sense of Jewish community and identity, however, this paper posits that for post-war Jews, engaging in acts of tikkun olam, was a way of repairing the world at large, healing the gaping wounds of WWII, and instantiating righteousness through art practice. Even while practicing assimilation, European émigré Jewish artists and their American born peers performed a particular kind of art making practice that engaged their Jewishness, albeit often surreptitiously, toward a more egalitarian, democratic ideology that reified the value of the individual in society as well as the healing power of art.
