Aharon Kotler (February 2, 1892 – November 29, 1962) was a Haredi Jewish rabbi and a prominent leader of Orthodox Judaism in Lithuania and the United States; the latter being where he founded Beth Medrash Govoha in Lakewood Township, New Jersey.

As of 2011, Beth Medrash Govoha is run by his grandson, Malkiel Kotler, and three of his grandsons-in-law, Yerucham Olshin, Yisroel Neuman, and Dovid Schustal.

[citation needed] Following his arrival in the United States, Kotler joined the presidium of the Vaad Hatzalah, working feverishly to save rabbis and yeshiva students who were trapped in Europe.

[9] Along with Eliezer Silver, Avraham Kalmanowitz and others, he worked day and night, using both private and government channels to try and save lives.
