HARDENBERGH, Henry Janeway (1847-1918) of New York City was an expert in hotel design, and he can be credited with two significant landmarks there including The Dakota Apartment House (1880) and The Plaza Hotel, Fifth Avenue at Central Park South (1905). Born in Brunswick, N.J., he trained in the office of Detlef Lienau from 1865 to 1870, then opened his own office in New York City. His extensive experience in the planning of large hotels in New York City, as well as hotels in Boston (The Copley Plaza Hotel, 1911-12) and in Washington (the Willard Hotel, 1901), led to his only Canadian commission, that for a major addition to the Windsor Hotel, Peel Street, MONTREAL, QUE. (1905-06; altered 1986). He collaborated with Bradford L. Gilbert of New York City, and with the Montreal firm of Hutchison & Wood on this commission, designing the eight storey wing in the Second Empire style and extensively renovating the lobby of the original hotel planned by another American architect William W. Boyington in 1878
