donated $30,000 for the construction of a building to be named "Peter Hertzog Theological Hall" in memory of her husband. Hertzog Hall (built 1855–1856) became a dominant feature on the hill, which became known locally as "Holy Hill". In November 1776, during the American Revolution, the hill was the site of a British artillery redoubt during the occupation of New Brunswick. Throughout the nineteenth century, the institution became known because of the efforts of missionaries serving throughout the world. In the 1870s, the campus was expanded with the construction of two buildings—one housing a gymnasium and additional lecture space; the second, a library. The seminary desired to build a library first, citing the need to house its expanding collection of books. However, local businessman and seminary benefactor James Suydam donated funds to build the gymnasium, to be named Suydam Hall, because he was extremely concerned with student health. Suydam Hall was built in 1873 and was designed by architect Henry Janeway Hardenbergh. Hardenbergh had finished completing the design for Kirkpatrick Chapel and Geology Hall on the Rutgers campus and later would become known for buildings in New York City, including the Plaza Hotel and Dakota Apartments. After receiving a donation from Gardner A. Sage earmarked for the construction of a library, the trustees commissioned Hardenbergh's former teacher, German-American architect Detlef Lienau, to design it. The Sage Library was completed in 1875. Lienau designed the library to complement Hardenbergh's (style) design for Suydam Hall. In the 1960s, Suydam Hall and Hertzog Hall were deemed to be inadequate for the administrative and instructional needs of the seminary. The trustees voted in 1966 to demolish both buildings and replace it with a modern one-story all-purpose building, Zwemer Hall, containing the seminary's chapel, faculty offices, and classroom facilities. In the late 1970s, during the tenure of seminary president Howard Hageman, the seminary revised its academic programs to focus on serving the needs of second career and bi-vocational students. This was intended to make theological education more accessible as the seminary transitioned from the 1980s to 2010s from "a predominantly residential school to one that is more than 90 percent commuter based." This transition meant that the seminary would serve an increasing number of second-career pastors who would study part-time. Another result of this transition was that the seminary's student body became the "most richly diverse" seminary in North America. Today, the New Brunswick Theological
