Arthur Marcus was an American textile businessman and philanthropist renowned for his contributions to Jewish and Israeli causes. Born in the United States, he built a successful career in the textile industry, which provided the financial foundation for his extensive charitable work. In 1979, Marcus co-founded the Central Fund of Israel with his wife, Hadassah Marcus, an organization dedicated to facilitating tax-deductible donations from American supporters to a wide array of Israeli institutions, including yeshivas, hospitals, and settlement projects. Under his leadership, the Central Fund became one of the largest conduits for U.S. philanthropy to Israel, distributing hundreds of millions of dollars over the decades. His philanthropy was deeply rooted in his commitment to Orthodox Judaism and Zionism, reflecting his personal values and family background. He and Hadassah worked tirelessly to support educational and religious initiatives in Israel, often focusing on underserved communities and frontier areas. Despite the organization's controversial associations with certain West Bank settlements, Marcus maintained a low public profile, emphasizing the importance of direct aid without political fanfare. His efforts strengthened networks between American Jewish donors and Israeli recipients, influencing the flow of funds in the global Jewish diaspora. Arthur Marcus passed away in 2019, leaving a legacy as a pivotal figure in transnational philanthropy. His work through the Central Fund continues to play a significant role in Israeli society, highlighting the intersections of business acumen, religious devotion, and geopolitical influence.
