Yeshivas Kol Torah was founded in 1939 by Yechiel Michel Schlesinger (1898–1948), born in Hamburg, Germany and Boruch Kunstadt, a dayan from Fulda, Germany. It was the first mainstream Haredi yeshiva to teach in Hebrew, as opposed to Yiddish, as was accepted at the time. This innovation had the crucial support of the Chazon Ish.
Tombstone of Rabbi Shlomo Zalman Auerbach; the inscription reads in part: "From a young age he spread Torah among the public, and had many students in Yeshivas Kol Torah".
After Schlesinger's death in 1949, Kol Torah was headed by Shlomo Zalman Auerbach, until his death in 1995.
Moshe Yehuda Schlesinger, eldest son of the founder, is currently serving as rosh yeshiva. Kol Torah is separated into two parts, the rabbinical college and the high school. The number of students in both combined reaches around 1000 students.
