Lenox Library (New York City)

The Henry Clay Frick House was the residence of the industrialist and art patron Henry Clay Frick in New York City. The mansion is located between 70th and 71st Street and Fifth Avenue on the Upper East Side of Manhattan. It was constructed in 1912–1914 by Thomas Hastings of Carrère and Hastings. It was transformed into a museum in the mid-1930s and houses the Frick Collection and the Frick Art Reference Library. The house and library were designated a National Historic Landmark in 2008 for their significance in the arts and architecture as a major repository of a Gilded Age art collection.

The Frick Art Reference Library Photoarchive is a study collection of more than one million photographic reproductions of works of art from the fourth to the mid-twentieth century by over 40,000 artists trained in the Western tradition located in the Frick Art Reference Library on the Upper East Side of Manhattan. It was founded in 1920 by Helen Clay Frick, the daughter of industrialist Henry Clay Frick, to facilitate object-oriented research. The documentation it offers records the essential elements of the biography of the work of art: the artist, title, present owner, as well as historical information such as changes of attribution, ownership and condition, all of which are essential for the study of the history of art.

The Frick Art Reference Library is the research arm of The Frick Collection. Its reference services have temporarily relocated to the Breuer building at 945 Madison Avenue, called Frick Madison, during the renovation of the Frick's historic buildings at 10 East 71st Street (between Madison and Fifth Avenue) in New York City. The library was founded in 1920 and it offers public access to materials on the study of art and art history in the Western tradition from the fourth to the mid-twentieth century. It is open to visitors 16 years of age or older and serves the greater art and art history research community through its membership in the New York Art Resources Consortium (which also includes the libraries of the Brooklyn Museum and The Museum of Modern Art). Within the library is the Center for the History of Collecting—a research organization that supports the study of the formation of collections of fine and decorative arts, both public and private, from Colonial times to the present through its fellowships, symposia, and publications.

The Frick Collection is an art museum in New York City. Its permanent collection (normally at the Henry Clay Frick House, currently at the Frick Madison) features Old Master paintings and European fine and decorative arts, including works by Bellini, Fragonard, Goya, Holbein, Rembrandt, Titian, Turner, Velázquez, Vermeer, Thomas Gainsborough, and many others. The museum was founded by the industrialist Henry Clay Frick (1849–1919), and its collection has more than doubled in size since opening to the public in 1935. The Frick also houses the Frick Art Reference Library, a premier art history research center established in 1920 by Helen Clay Frick (1888–1984).

The monument was erected in 1898 by the Art Societies of New York, a coalition of a number of municipal cultural institutions associated with Hunt: the Century Association, the Municipal Art Society (whose first president, in 1892, was Hunt), the Metropolitan Museum of Art (whose main building was designed by Hunt), the Artist Artisans of New York, the Architectural League, the National Sculpture Society, the National Academy of Design, the Society of American Artists, the American Institute of Architects (co-founded by Hunt in 1857), the American Watercolor Society, and the Society of Beaux-Arts Architects.

The C. Ledyard Blair House was a mansion on 2 East 70th Street, at the corner with Fifth Avenue, on the Upper East Side of Manhattan in New York City. It was constructed for banker C. Ledyard Blair and designed by Carrère & Hastings. The house was constructed from 1914 to 1917 and occupied almost 7,300 square feet (680 m2).

907 Fifth Avenue is a luxury residential housing cooperative in Manhattan, New York City, United States. The 12-story, limestone-faced building is located at Fifth Avenue and 72nd Street on a site once occupied by the 1893 residence of James A. Burden, which had been designed by R. H. Robertson. The apartment block, built in 1916, was the first apartment building to replace a private mansion on Fifth Avenue above 59th Street. It was converted to a cooperative in 1955. J. E. R. Carpenter was the architect; he would be called upon to design many of the luxury apartment buildings that gave a new scale to Fifth Avenue in the 'teens and twenties of the 20th century. The building won him the 1916 gold medal of the American Institute of Architects.The building has the aspect of an Italian Renaissance palazzo, built around a central court. Its first four floors are lightly rusticated; deep quoins carry the rusticated feature up the corners to the boldly projecting top cornice. A strong secondary cornice above the fourth floor once made a conciliatory nod to the cornice lines of the private houses that flanked it, whose owners had fought its construction in court. When it opened, there were two 12-room apartments on most floors.

The Herbert N. Straus House is a large town house at 9 East 71st Street, just east of Fifth Avenue, on the Upper East Side of Manhattan in New York City. The exterior was designed by Horace Trumbauer and completed in 1932. A roof extension was added in 1977. The size of the house was believed to be 21,000 square feet (2,000 m2) in the late 1980s, and by 2003 had been enlarged to 51,000 square feet (4,700 m2), spread over nine floors. A 15-foot high (4.6 m) oak door and large arched windows are distinctive features of the limestone exterior. A heated sidewalk is located in front of the house.Vicky Ward in 2003 described the house as "the crown jewel of the city's residential town houses...it sits on—or, rather, commands—the block of 71st Street between Fifth and Madison Avenues. Almost ludicrously out of proportion with its four- and five-story neighbors, it seems more like an institution than a house" and that it was believed to be the largest private residence in Manhattan. The house's 2008 property tax bill was the fourth highest for a single residence in New York City. In 2019 it was valued at $77 million by the United States Attorney for the Southern District of New York and at $56 million by the New York City Department of Finance.
