Mordechai Yissachar Ber Leifer (Hebrew: מרדכי יששכר בער לייפער; 1955 – 4 October 2020) was the third Rebbe of the Pittsburgh Hasidic dynasty. Born in the United States, he joined his father, Grand Rabbi Avraham Abba Leifer, in Ashdod, Israel, to serve as rosh yeshiva of a new Pittsburgher yeshiva in that city in 1981. After succeeding his father as Rebbe, he expanded the Hasidic presence in Ashdod with new schools and institutions, and increased the number of Pittsburgher families to nearly 200 in Ashdod. He also shepherded Pittsburgher Hasidim in Jerusalem, Bnei Brak, Beit Hilkia, New York City, and California.^[1] An accomplished Torah scholar and musical composer, he led the Hasidut for three decades until his death in 2020.
