Moshe Aharon Poleyeff (1888 â 1966) was an American rabbi, teaching at Yeshiva University (YU) in New York where he was a Rosh Yeshiva for over 45 years, training generations of rabbis, including Mordechai Gifter.
Poleyeff was born in 1888, in Timkovitz, near Slutsk, south of Minsk, Belarus (White Russia).
He was a student of Rabbi Isser Zalman Meltzer, by whom he was ordained in 1910. He married Rochel in 1912.
Poleyeff arrived in the United States in 1920, and immediately began a teaching career at Yeshiva University in New York, where for about 46 years he was a YU/RIETS Roshei Yeshiva and had thousands of students. His "Thursday Shiur" teaching methodology incorporated a student-presented topic, followed by discussion; he helped the student prepare the prior week or two.
Poleyeff died 2 Kislev 5727 (November 1966).
