Yerucham Levovitz

Rabbi Yeruchem Halevi Levovitz (or Leibovitz) (Hebrew: ירוחם ליבוביץ‎‎; ca. 1873-1936), also known by his hundreds of students simply as The Mashgiach, was a famous mashgiach ruchani and baal mussar (ethicist) at the Mir yeshiva in Poland.

He was born in 1873 (5633 in the Jewish calendar) in Lyuban, Minsk Voblast, Belarus (near Slutsk) to Avraham and Chasha Levovitz. He received his education in the yeshivas of Slobodka and Kelm.

He was a disciple of Rabbi Nosson Tzvi Finkel, Simcha Zissel Ziv of Kelm as well as Rabbi Yisrael Meir Kagan (Chofetz Chaim) of Radin.

He was the spiritual leader of the Mir Yeshiva in Poland until his death in 1936. His disciples were said to have followed his every word, never doing anything that they "felt" he would not want them to do. Most of the leaders of the yeshivas of inter-war Poland were Rabbi Yeruchom's disciples. They would come on occasion to visit him and seek his advice.

After World War II, much of orthodox Jewry in Europe was wiped out, along with their many yeshivas (Jewish schools of higher learning). One of the only yeshivas to survive as a whole body was the Mir Yeshiva, which managed to escape miraculously to Shanghai, China, and then on to America. Many of the new leaders of the American and Israeli yeshivas in the post-war period were students of the Mir, and thus followers of Rabbi Leibovitz.
