, namesake of the Seminary The first Jewish schools in New York were El Hayyim and Rabbi Elnathan's, on the
Lower East Side. In 1896, several New York and Philadelphia rabbis agreed that a rabbinical seminary based on the traditional European
yeshiva structure was needed to produce American rabbis Bernard L. Levinthal and other leading Orthodox rabbis of the day founded the school, later the "Yeshiva College of America", before finally settling simply on
Yeshiva College., which would be the undergraduate college for men of what later became Yeshiva University. In 1926, it bought a three-block site in Washington Heights, built its first building, and moved its operation there. , that building continued to house the
Yeshiva University (YU) affiliated High School for Boys, but all other operations had moved to other buildings later constructed on the expanded campus surrounding it. The high school, previously part of RIETS, became a separate entity, and RIETS became exclusively a college-level program, including granting of degrees via
semikhah (rabbinical ordination). Secular studies were added, with the RIETS
rosh yeshiva (dean) also serving as president of the college secular academic programs while
Moshe Soloveichik served as co-head of RIETS. This arrangement continued into the 1940s. However, the second
president,
Samuel Belkin, legally separated the two institutions in order to obtain
United States government funding and research grants for a variety of YU's secular departments due to the
separation of church and state in the United States. RIETS scholar
Joseph B. Soloveitchik strongly opposed the split, but Belkin prevailed and, following the split, remained both the official rosh yeshiva of RIETS and president of YU. Despite the separation, the identities have continued to be blended Both the religious seminary and the college undergraduate Talmudic department are called RIETS, and have the same faculty and students. With the 2003 appointment of
Richard Joel, a
layman, as president of YU, the dual role ended. Joel's predecessor,
Norman Lamm, continued as the official rosh yeshiva of RIETS with Richard Joel being the Chief Executive and responsible for fundraising and administrative issues.
Menachem Penner became the dean of RIETS in 2013 after
Yona Reiss resigned to take the position as head of the
Chicago Rabbinical Council. In 2023, Rabbi Penner left his position as dean in order to assume the role of executive vice president of the
Rabbinical Council of America. Following Rabbi Penner's departure, Rabbi Michael Taubes was appointed as interim dean of RIETS. Rabbi Penner currently serves as dean emeritus. In August, 2024, Rabbi
Aryeh Lebowitz was appointed as the Abraham Arbesfeld Torah Dean of RIETS, and Rabbi Yosef Kalinsky was appointed as the Max and Marion Grill Administrative Dean of RIETS.{{cite web |title=New Leadership at YU RIETS to Start the Fall Semester At the time of Reiss's appointment, RIETS absorbed the academic administration of the Undergraduate Torah Studies programs affiliated with Yeshiva College and
