Joseph Herman Hertz (25 September 1872 – 14 January 1946) was a Jewish Hungarian-born rabbi and biblical scholar. He is most notable for holding the position of Chief Rabbi of the United Kingdom from 1913 until his death in 1946, in a period encompassing both world wars and the Holocaust. Hertz edited a notable commentary on the Torah (1929–36, one volume edition 1937). Popularly known as the Hertz Chumash, this classic Hebrew-English edition of the Five Books of Moses, with corresponding Haftorahs, is used in synagogues and classrooms throughout the English-speaking world. He also edited a Hebrew-English edition of the Jewish Prayer Book or Siddur (1946), and contributed to the Jewish Encyclopedia and the Encyclopædia Britannica.
