Hardenbergh's great-great-grandson, architect Henry Janeway Hardenbergh (1847–1918) was hired by the trustees of Rutgers College to design three buildings for the campus—Geology Hall (1871–72), Kirkpatrick Chapel (1873), an addition to the grammar school (now Alexander Johnston Hall)—and to design Suydam Hall (demolished) on the former campus of the New Brunswick Theological Seminary, before a career designing large hotels and buildings in New York City. In Kirkpatrick Chapel, the large stained-glass window in the chancel above the altar, titled "Jesus, the Teacher of the Ages", was donated to the college by Henry Janeway Hardenbergh after the renovation of the chapel in 1916 and dedicated to his great-great-grandfather. This window is one of four in the chapel designed and crafted in the studios of Louis Comfort Tiffany (1848–1933).
