Alter Chanoch Henoch Hakohen Leibowitz (June 2, 1918[1] – April 15, 2008)[2] was an Orthodox rabbi who was Rosh Yeshiva (dean) of Yeshivas Rabbeinu Yisrael Meir HaKohen, which was founded by his father Rabbi Chaim Dovid Hakohen Leibowitz in 1933.

He came to America in 1926 when his father was hired by Mesivta Torah Vodaath as a teacher.

In 1933, his father left Torah Vodaath and founded Yeshivas Rabbeinu Yisrael Meir HaKohen.

He built a network of Jewish educational institutions in the United States, Canada and Israel.

David Paterson reportedly called Leibowitz “the most honest person in the state of New York”.
