R. Tzvi Pesach Frank

Rabbi Tzvi Pesach Frank (1873–1960) was one of the preeminent halakhic authorities of twentieth-century Jerusalem and a revered teacher of Torah. Born in Eastern Europe, he settled in the Holy Land and became known for his meticulous scholarship, penetrating logical mind, and unwavering commitment to Jewish law. He served as a posek (halakhic decisor) for Jerusalem's Jewish community and was consulted on matters of great complexity by scholars across the Diaspora. His published responsa, known as Har Tzvi (named after his surname), demonstrate his mastery of the entire Talmudic corpus and his ability to synthesize sources across generations. He was deeply respected by his students and contemporaries for his integrity, humility, and dedication to the precise application of halakha in modern circumstances.
