הרב אהרן מקרלין

Aharon ben Jacob Perlov of Karlin, (1736-1772), known among the Ḥasidim as Rabbi Aharon the Great, was one of the early rabbis of the Hasidic movement who significantly contributed to its rapid spread in Eastern Europe. He is recognized as the founder of the Hasidic center in Karlin, a suburb of Pinsk in the Polish–Lithuanian Commonwealth. He was distinguished for the fiery eloquence of his exhortations (sermons) and is known simply as the "Preacher" or "Censor".
