Meïr Leibush ben Yehiel Michel Wisser (Russian: Меир-Лейбуш бен Йехиэл-Михл) (March 7, 1809 – September 18, 1879), better known as The Malbim (Hebrew: מלבי"ם), was a rabbi, master of Hebrew grammar, and Bible commentator. The name "Malbim" was derived from the Hebrew initials of his name. He used this acronym as his surname in all his published works, and became known by it in common usage.
Malbim was born in Volochysk, Volhynia to Yehiel Michel Wisser and his wife. His father educated in Hebrew and the Talmud. After being orphaned as a child, Meïr was cared for and educated by his stepfather, Rabbi Leib of Volochysk.
At the age of 13, he went to study in Warsaw. He was known there as "the iluy from Volhynia." He showed talent from his early childhood, and his works indicate that he had a considerable knowledge of secular sciences and history. From 1838 to 1845 he served as rabbi of Wreschen. In the latter year he was called to the rabbinate of Kempen, where he remained until 1859. He was thereafter also known as der Kempener Magid.
