Rabbi Aryeh Leib ben Shaul Loewenstamm was a leading Polish and Dutch rabbi who served as Chief Rabbi of Amsterdam from 1740 until his passing. He republished the responsa of Rabbi Moshe Isserles with his own supercommentary, Kunteres Aḥaron, which drew parallels from the responsa of the Maharshal. His work established him as a halachic authority.
