Hotel Astor was a hotel located in the Times Square area of Manhattan, New York City, in operation from 1904 through 1967. The former site of the hotel, the block bounded by Broadway, Astor Plaza, West 44th Street, and West 45th Street, is now occupied by the high-rise 54-story office tower One Astor Plaza.
With its elaborately decorated public rooms and its roof garden, the Astor Hotel was perceived as the successor to the Astor family's Waldorf-Astoria on 34th Street. William C. Muschenheim and his brother, Frederick A. Muschenheim conceived plans for the grand hotel in 1900. The area was then known as Longacre Square and stood beyond the fringe of metropolitan life, the center of New York's carriage-building trade. The Muschenheim brothers became the proprietors for absentee landlord William Waldorf Astor, from whom they leased the land. The hotel opened on September 9, 1904.
The 35,000 square feet (3,300 m2) Hotel Astor was built in two stages, in 1905 and 1909–1910, by the same architects in the same style. Upon completion, the structure occupied an entire city block at a reported total cost of $7 million. Architects Clinton & Russell had designed a number of Astor commissions; here they developed a very Parisian "Beaux Arts" style completed with green-copper mansard roof. Its eleven stories contained 1000 guest rooms, with two more levels underground for its extensive "backstage" functions, such as the wine cellar.
The Astor was an important element in the growth of Times Square and its character as an entertainment center. In 1904, New York Times publisher Adolph S. Ochs moved his newspaper's operations to a new tower on 42nd Street in the middle of Longacre Square, and Ochs persuaded Mayor George B. McClellan, Jr. to build a subway station there and rename it Times Square. The Theater District would soon occupy magnificent new auditoriums along Forty-second Street, and electric lighting transformed this strip of Broadway into the "Great White Way".
