# Isaac Breuer

Isaac Breuer (Hebrew: יצחק ברויאר; 1883–1946) was a rabbi in the German Neo-Orthodoxy movement of his maternal grandfather Samson Raphael Hirsch, and was the first president of Poalei Agudat Yisrael.

## Biography

Isaac Breuer was born in Pápa, Austria-Hungary to Salomon Breuer, and lived most of his years in Frankfurt. His brother was Rabbi Joseph Breuer. He attended Hirsch's Realschule school, and received rabbinical ordination at age 20 from his father's yeshivah. He studied law, jurisprudence, and philosophy at Marburg University, and until 1936 practiced law in Frankfurt.
In 1936 Breuer immigrated to Jerusalem, where he led Poalei Agudat Yisrael and represented it before the Peel and Anglo American Commissions. He married Jenny Eisenmann, a granddaughter of Eliezer Liepman Philip Prins. His five children were Jacob (Bub), a lawyer who played a role in the Eichmann trial (1915–2008), Mordechai (1918–2007), Ursula (1919–2006, married Hermann Merkin), Tzipora (Tzip) Breuer Schneller Meir (1926–2020) and Simeon Breuer (1922–1943). His son-in-law Hermann Merkin helped to establish the Isaac Breuer College of Hebraic Studies (IBC program) at Yeshiva University in his memory.
Breuer died in Jerusalem, Mandatory Palestine in 1946. Michal Lupolianski, the wife of former mayor of Jerusalem Uri Lupolianski, is one of his grandchildren.

## Views on Zionism

Although Hirsch's neo-Orthodoxy movement had defined itself from the start largely as an opposition to the German Reform movement, Isaac Breuer already regarded the Reform movement of his day as essentially the impotent and dying remnant of the Haskalah (Biemann 2000). Breuer saw the real enemy of Orthodoxy in both political Zionism and Religious Zionism, which he considered especially dangerous because it possessed an authentic Jewish instinct and impulse. The goals of the Zionists paralleled the goals of his own Agudah organization in many areas ("reunification of land and nation"), but without the stress which Agudah laid on adherence to halachah and tradition (Biemann 2000). Indeed, Breuer envisioned a Messianic Torah state in the land of Israel, and could not abide the idea of "reunification of land and nation" coming to pass through the agency of secular Zionist forces in the form of a secular state.
