Leib Tropper

Rabbi Leib Tropper (born 1950 in New York City) is founder of the Kol Yaakov Yeshiva and Torah Center in Monsey, New York. He is a grandson of the late Rabbi Leib Forer, the "Valbolneker Iluy".

He was educated at the Rabbi Jacob Joseph School, the Talmudical Yeshiva of Philadelphia, the Telshe Yeshiva in Cleveland, and then at Yeshivas Torah Ore in Jerusalem, under the leadership of Rabbi Chaim Pinchus Scheinberg. He received four semichas: from Rabbi Serayah Deblitzky, a student of the Chazon Ish; Rabbi Ovadia Yosef, former Sephardi chief rabbi of Israel; Rabbi Betzalel Zolty, Ashkenazi chief rabbi of Jerusalem; and Rabbi Elazar Shach, a rosh yeshiva at the Ponevezh Yeshiva in Israel.

After leaving Torah Ore, Tropper accepted a position at the nascent Ohr Somayach institutions. After five years in Jerusalem teaching baalei teshuva, Tropper returned to the United States to become the educational director of Ohr Sameach, New York located in Yonkers and Monsey. In 1981, Tropper joined Rabbi Avrohom Gershon Tress zt"l in founding a new yeshiva for baalei teshuva, the Kol Yaakov Torah Center, and became its rosh yeshivah.

In 1995, Tropper founded a new outreach program called Horizons, focusing on educating and inspiring the unaffiliated to experience a Torah lifestyle. As its director, Tropper traveled the world lecturing and teaching. He has also written three books: a halachic work based on the decisions of his mentor Rabbi Scheinberg, a guide to the laws of yichud, a discussion of the prohibition of seclusion between men and women.
