History

Designed by local architect and builder Nicholas Wyckoff in 1830, Alexander Johnston Hall served as the home of the Rutgers College Grammar School, later known as the Rutgers Preparatory School.^[4] In 1870, the Rutgers College trustees hired architect Henry Janeway Hardenbergh (1847–1918) to design a two-story addition for the building.^[4] It was the first of three commissions Hardenbergh designed for the college—the other two being Geology Hall (1872) and Kirkpatrick Chapel. The Rutgers Preparatory School used this building from 1830 to 1963. The school, which was chartered with Rutgers as "Queen's College" in 1766, is now an independent school located on a 45-acre campus on Easton Avenue in Somerset, New Jersey. In 1964, the university renamed the building to honor 1870 graduate, Alexander Johnston, a historian and classics instructor at the school. Johnston had taught future Rutgers president William H. S. Demarest here.^[4]
