Rabbi Moshe Hauer, the executive vice president of the Orthodox Union, died after suffering a sudden heart attack earlier this week.

Jewish communal leaders remembered Hauer as a friend, a faithful and committed leader and a source of wise counsel.

Hauer had served in his role at the OU since May 2020, acting as the organization’s professional and rabbinic leader and primary spokesperson, as well as helping to lead the organization’s outreach to U.S. administration officials and lawmakers.

“Rabbi Hauer was a true talmid chacham, a master teacher and communicator, the voice of Torah to the Orthodox community and the voice of Orthodoxy to the world. He personified what it means to be a Torah Jew and took nothing more seriously than his role of sharing the joy of Jewish life with our community and beyond,” OU President Mitchel Aeder and Chief Operating Officer Rabbi Josh Joseph said in a joint statement.

“Rabbi Hauer’s leadership was marked by unwavering dedication, deep compassion, and a vision rooted in faith in Hashem, integrity, and love for Klal Yisrael,” Aeder and Joseph continued. “Whether through his inspiring words, thoughtful counsel, powerful advocacy, or quiet acts of kindness, Rabbi Hauer uplifted those around him and made an impact on every person he encountered.”

Prior to his role at the OU, Hauer served for more than 26 years as the lead rabbi at Bnai Jacob Shaarei Zion Congregation in Baltimore.

William Daroff, the CEO of the Conference of Presidents of Major American Jewish Organizations, told Jewish Insider he was “shattered by the sudden passing of my dear friend and partner, Rabbi Moshe Hauer.”

“We just spoke this past Friday and texted on Monday, when he was overflowing with joy at the miracle of the hostages’ freedom and the unmistakable hand of Hashem in it. Rabbi Hauer was a trusted advisor, cherished colleague, and wise counselor to me, a bridge-builder whose faith, humility, and moral clarity inspired all who knew him. His loss leaves a deep void for all who loved and learned from him,” Daroff continued.

“He was a wise and thoughtful leader for so many dimensions of the OU’s activities — That included his partnership with me in advocacy,” Nathan Diament, the OU’s executive director of public policy, told JI. “Rabbi Hauer deeply believed in the imperative for the Orthodox community to be fully and proactively engaged with the world at large — not isolated from it. And for us to work to better society by advancing Torah values. In fact, the last time I was with him in person was just a couple of weeks ago — we met with senators and senior White House officials to discuss key issues and values.”

Sheila Katz, the CEO of the National Council of Jewish Women, said in a Facebook post, “Some leaders shape institutions. Others shape hearts. Rabbi Moshe Hauer did both.”

“After October 7, we found ourselves advocating side by side at the Department of Education and Department of Justice, in Congress, in the White House, and in the Knesset, determined to show what Jewish unity could look like,” Katz said. “It wasn’t unity for its own sake, but unity in service of the Jewish people, to advocate together for Jewish women, for the Orthodox community, and for all of us. Him, an Orthodox male rabbi. Me, a Reform Jewish progressive woman. Together, we were an unlikely duo that came together to advocate against antisemitism, to promote safety in Israel, and for the return of the hostages.”

“I’m grateful he lived to see all the living hostages come home. But I’m heartbroken that we won’t get to be with him for all that’s next, for the rebuilding, the hope, and the unity he modeled so powerfully,” Katz continued. “All we can do is continue to build a better world with love, and with Jewish life and wisdom, to honor the memory of our dear friend, Rabbi Hauer.”

Hauer was ordained at Ner Israel in Maryland and received a graduate degree from Johns Hopkins University. 

According to the OU, during his time at Bnai Jacob Shaarei Zion he “was active in local communal leadership in many areas, with an emphasis on education, children-at-risk, and social service organizations serving the Jewish community… led a leadership training program for rabbis and communal leaders, and was a founding editor of the online journal Klal Perspectives.”
