Tzvi Pesach Frank
Frank was born in Kovno, Lithuania, the son of Yehuda Leib Frank and Malka Silman. He studied in Lithuanian yeshivas, learning under Rabbi Eliezer Gordon, among others. In 1892, he emigrated to Palestine with his brother Tanhum, his sister Zippora and his first cousin, Rabbi Shmuel Hillel Shenker. His parents arrived in 1893. Tzvi Pesach continued his studies in yeshivas in Jerusalem. His father was one of the founders of Hadera.
In 1907, Frank was appointed dayan in the Beth Din of the Edah HaChareidis headed by Rabbi Shmuel Salant, the Chief Rabbi of Jerusalem. Frank served on this Beth Din for nearly 60 years, eventually becoming Av Beit Din (head of the rabbinical court) and Rav of Jerusalem.
Frank was active in establishing the office of the Chief Rabbinate of Israel and was instrumental in appointing Rabbi Abraham Isaac Kook as the first Ashkenazi Chief Rabbi. Rabbi Jacob Meir, the first Sephardic Chief Rabbi, had been in Palestine prior to the formal development of the office.
Frank was recognized for his efforts by The Pacific Club in 1917 for advancing American relationships in the region. However, although Frank was a member of the Israeli Chief Rabbinate Council from its inception in 1921, he did not attend meetings of that body for six years prior to his death. One of his last acts was to send a letter to the meeting of rabbis in Tel Aviv, supporting the boycott of elections to the Chief Rabbinate.

Death and legacy
Frank died on 10 December 1960 (21 Kislev 5721) and was buried on Har HaMenuchot. His funeral was attended by many thousands of mourners. All of Israel's Beth Dins were closed for the day and the Cabinet adjourned so that ministers could attend the funeral. Eulogies were delivered by Rabbi Yitzhak Nissim, the Sephardi Chief rabbi; Rabbi Isser Yehuda Unterman, Chief rabbi of Tel Aviv; and Rabbi R. Katz, Chief rabbi of Petah Tikva.
His son, Yaakov Frank, was a member of Israeli Knesset from Labor Party. His grandson, Zvi Pesach Frank, is a co-founder of an Israeli hi-tech startup, Interwise. His son-in-law, Rabbi Menachem Sacks, was a leader in Jewish education in Chicago for nearly six decades. Another son-in-law, Shmuel Rozovsky (1913–1979) was a Rosh Yeshiva at the Ponevezh Yeshiva located in Bnei Brak, Israel, and was counted amongst the great rabbis of his generation.
His great-grandson, Rabbi Daniel Landes, is the Rosh Yeshiva of the Pardes Institute in Jerusalem. Another great-grandson, Rabbi Yonason Sacks, is currently the Rosh Yeshiva of Beis Medresh L'Talmud/Lander College for Men, a division of Touro College in New York, as well as the rav at the Agudas Yisroel of Passaic Park in Passaic, New Jersey.

- Richard Bercuvitz, Interview with Frank's daughter Esther Rosovsky, 1994; she stated that he came with his brother Tanchum and his cousin Shmuel Hillel Shenker in 1892 (5653). They came from Odessa to Jaffa. Turkish guards refused to let them disembark, so they continued to Alexandria, Egypt, where they remained for 3 weeks. After Simchat Torah, the same boat came back from Odessa and they got on an came back to Jaffa. Shabetai Rozental, in his book on Zvi Pesach Frank, does not mention Frank's sister and states that they went to Port Said in Egypt and arrived in Jaffa in the fall of 1892. Zvi Pesach's father had been in Palestine for some time prior to this.
