Isaac Halevi Herzog (born November 1888, Łomża, Poland—died July 25, 1959, Jerusalem) was a scholar, author, religious philosopher, lecturer, chief rabbi of the Irish Free State (1925–36), and Ashkenazi chief rabbi of Palestine (later Israel) from 1936. Herzog made significant contributions to reconciling the necessities of modern living with the demands of the Talmud. For more than 20 years he was a leading Jewish representative to the conferences and commissions organized to find a solution to the Arab–Jewish conflict in Palestine and to attempt to find refuge and help for the victims of the Nazi persecution of Jews. His son Chaim Herzog and his grandson Isaac Herzog both served as presidents of Israel.
