Jonathan Steiner Wolf
December 22, 1951 – May 4, 2026

Jonathan Steiner Wolf devoted his life to the work of community—creating it, challenging it, and expanding what it could mean.

For more than half a century, he stood at the intersection of Jewish learning, social activism, and lived experience, refusing to separate the ethical from the spiritual, or the political from the personal. He was not simply a participant in Jewish communal life; he was one of its architects—often working outside formal structures, sometimes ahead of them, and frequently pushing them to become more inclusive, more just, and more alive.

As President and CEO of YASHAR: The Institute for Jewish Activism, a role he held for over two decades, Jonathan dedicated himself to equipping others with the tools of organizing, grounded in Torah and directed toward real-world impact. Through teaching, organizing, writing, speaking, and funding, he helped seed and sustain a wide constellation of initiatives—supporting movements for human rights, environmental responsibility, interfaith understanding, and Jewish pluralism.

Over the course of his life, he played a formative role in creating, strengthening, or guiding dozens of organizations, including the Beyond Shelter Coalition, Jewish Vegetarians of North America, the Jewish environmental network later known as Hazon, Limmud communities in multiple cities, and interfaith and human rights initiatives in both the United States and Israel. He moved fluidly between New York, Chicago, Washington, and Jerusalem, carrying ideas, relationships, and energy from one place to another—often before others recognized the connections were needed.

He was, at heart, an educator.

For nearly five decades, Jonathan taught adults in synagogues, conferences, and informal settings across North America and the United Kingdom. His subjects ranged widely—feminism and halacha, pluralism, political ethics, environmental responsibility, vegetarianism, and the evolving moral questions of Jewish life. He believed learning was not only about the transmission of knowledge, but about awakening responsibility. He added a joyous sense of humor and a quick wit to the profound substance of what he taught and wrote. His students, family and friends have countless stories of his hilarious jokes, skits and songs.

In a sprawling Upper West Side apartment, he created something akin to a living laboratory of Jewish life. As director of the West Side Center for Jewish Life, he hosted Shabbatot, study sessions, holiday celebrations, and political conversations that blurred the boundaries between home, synagogue, and movement. It was messy, alive, and deeply generative—an experiment in what community could be when people showed up and fully engaged with each other.

He carried that same spirit into his earlier work at Lincoln Square Synagogue, where he built one of the most ambitious lay-led community action programs in North American Jewish life—engaging volunteers in everything from social services to political advocacy to direct aid for those in need.

Jonathan’s path began in Evanston, Illinois, where even as a student he was already creating—editing a major high school newspaper, launching publications, and bringing people together around ideas. At Columbia University and the Jewish Theological Seminary, he continued that trajectory, combining intellectual inquiry with activism, including organizing protests against the Vietnam War and working with marginalized populations. Later, he founded and led the Orthodox Jews for Obama.

He often described his education as a “Yeshiva of Hard Knocks,” a phrase that captured both his humility and his conviction that learning happens through engagement with the real world.

Throughout his life, Jonathan resisted narrow definitions—of Judaism, of politics, of identity. He believed in a Judaism that could hold complexity: tradition and change, particularism and universalism, devotion and dissent. He saw activism not as opposition, but as obligation.

Those who knew him experienced a person of intensity, conviction, and generativity—someone who could convene, provoke, support, and inspire, often all at once.

He was the beloved father of Mengistab Tesfemariam Wolf, and the devoted son of Rabbi Arnold Jacob Wolf z”l and Margery Steiner Wolf z”l and beloved step-son of Grace Wolf. He was a brother of Benjamin (Donna) Wolf and a step-brother to Sara Berger, Justine (Anthony Scott) Henning, Sarah-Anne (John) Schumann and Dara Henning, along with many nieces and nephews. In an act of both scholarship and love, he edited and brought forward a collection of his father’s writings, The Unfinished Rabbi, helping to ensure that a generation’s voice and vision would continue to be heard.

Jonathan Steiner Wolf’s legacy lives not in any single institution, but in the countless communities he helped bring into being, and in the people who continue the work he set in motion.
