Aryeh Leib Baron

Rabbi Aryeh Leib Baron was born on March 2, 1912 in the town of Horodok[lower-alpha 1] in the Minsk Region of Belarus, then part of the Russian Empire,[1] to Reuven Baranovich (his last name, Baron, is a shortened version of "Baranovich"). His Hebrew birthday was on Taanis Esther.[2] In his youth, he studied under Rabbi Avraham Kalmanowitz in Rakov and later at a yeshiva in Stowbtsy, Belarus.[3] As a younger man, he studied in the Baranovich Yeshiva under Rabbi Elchonon Wasserman and Rabbi David Rappoport. Rabbi Wasserman used the notes that he took in shiur (class) to publish his sefer, Kovetz He'aros. He also developed a close relationship with Rabbi Yisroel Yaakov Lubchansky, the mashgiach in Baranovich and ate Shabbos meals at his house for a time. In the early 1930s, Rabbi Baron went to study in the Mir Yeshiva, where he stayed until the outbreak World War II, when the yeshiva escaped to Vilnius. In 1940, with the aid of Japanese consul to Kaunas, Chiune Sugihara, the yeshiva fled Nazi Europe to Kobe, Japan, from where they were transferred to Shanghai.[4] After several years, much of the yeshiva emigrated to the United States, Rabbi Baron included. He then married the daughter of Rabbi Chaim Eliezer Samson, rosh yeshiva of Yeshivas Chofetz Chaim in Baltimore.[5]

In 1948, Rabbi Baron was appointed rosh yeshiva of Yeshiva Merkaz HaTorah in Montréal,[6] replacing Rabbi Eliyahu Simcha Chazzan who had become rosh yeshiva of Torah Vodaath in New York in 1945.[7] He stayed as rosh yeshiva for 24 years, often sending students to learn in the major yeshivos in the United States. In 1973, he founded Beis Medrash Merkaz HaTalmud which he led until his move to Israel. He also founded Yeshiva Ahavas HaTorah Baranovich in Jerusalem.[8]

On October 3, 2011, Rabbi Baron passed away,[9] a few months after his hundredth birthday. He was buried on Har HaMenuchos.[10]
