with the 1.2-million-member denomination. In 1812, the seminary boasted three students and Archibald Alexander as its first professor. By 1815 the number of students had gradually increased and work began on a building: Alexander Hall was designed by John McComb Jr., a New York architect, and opened in 1817. The original cupola was added in 1827, but it burned in 1913 and was replaced in 1926. The building was simply called "Seminary" until 1893, when it was officially named Alexander Hall. Since its founding, Princeton Seminary has graduated approximately 14,000 men and women who have served the church in many capacities, from pastoral ministry and pastoral care to missionary work, Christian education and leadership in the academy and business. The seminary was made famous during the 19th and early 20th centuries for its defense of Calvinistic Presbyterianism, a tradition that became known as Princeton Theology and greatly influenced Evangelicalism during the period. Some of the institution's figures active in this movement included Charles Hodge, B.B. Warfield, J. Gresham Machen, and Geerhardus Vos. Liberalism and split In response to the increasing influence of theological liberalism in the 1920s and the Fundamentalist–Modernist Controversy at the institution, several theologians left to form the Westminster Theological Seminary under the leadership of J. Gresham Machen. The college was later the center of the Fundamentalist–Modernist Controversy of the 1920s and 1930s. In 1929, the seminary was reorganized along modernist lines, and in response, Machen, along with three of his colleagues: Oswald T. Allis, Robert Dick Wilson and Cornelius Van Til, resigned, with Machen, Allis and Wilson founding Westminster Theological Seminary in Glenside, Pennsylvania. In 1958, Princeton became a seminary of the United Presbyterian Church in the U.S.A., following a merger between the Presbyterian Church in the U.S.A. and the United Presbyterian Church of North America, and in 1983, it would become a seminary of the Presbyterian Church (U.S.A.) after the merger between the UPCUSA and the Presbyterian Church in the U.S. Ties to slavery In 2019, the Seminary announced that it would spend $27 million on "scholarships and other initiatives to address its historical ties to slavery". 2022 President Rev.
