Julius Rosenwald rose to meteoric wealth at the helm of Sears, Roebuck and Co., yet his most important legacy stands on the pioneering changes he introduced to the practice of philanthropy. His passionate support of Jewish and African American causes continues to influence lives to this day, though he refused to have his name attached to the buildings, projects, or endowments he supported. Hasia R. Diner’s biography of Rosenwald explores topics of tikkun olam, philanthropy, and the importance of partnership in building a better future.
