Leo Jung

Rabbi Leo Jung (June 20, 1892 in Uherský Brod, Moravia – December 19, 1987 in New York City, United States) was one of the major architects of American Orthodox Judaism.

His father, Rabbi Dr. Meir Tzvi Jung held rabbinic post in Mannheim then was elected Rabbi of Uherský Brod in 1890. Rabbi Meir Tzvi Jung believed in the Torah im Derekh Eretz (Torah combined with worldly activity) philosophy of Rabbi Samson Raphael Hirsch. Later he moved to London. Rabbi Leo Jung's father founded schools in Uherský Brod, Cracow and London, where both religious and secular learning took place. In London, Rabbi Meir Tzvi Jung was a leader in Agudat Yisrael, and the Sinai Movement. The Sinai Movement was a movement in which young men would meet for the purpose of studying Talmud and socializing. At his death in June 1921, Rabbi Jung was the Chief Minister of the Federation of Synagogues in England, an appointment he had held since 1912.

In 1916, Rabbi Leo Jung became the director general of the Sinai League of which his father was founder and president. Rabbi Meir Tsevi founded the journal, "The Sinaist", based on the Torah im derekh eretz philosophy. Leo Jung became the editor of this bi-monthly journal, which he claimed expressed his father’s philosophy, "study is great, for it leads to (right) action".

Rabbi Jung, like his father, received a secular and Talmudic education. He attended Cambridge University and he received his doctorate from the University of London. In 1910 he attended the Yeshiva of Eperies and in 1911 he went to study in Galanta, Hungary. He also attended the Hildesheimer Rabbinical Seminary in Berlin. Jung claimed that he received three rabbinic ordinations, from Rabbi Mordechai Zevi Schwartz, Rabbi Abraham Isaac Kook and Rabbi David Zvi Hoffmann of Berlin. He regarded his semikhah from David Hoffman as, "his last and most cherished semikhah"
