From: http://en.wikipedia.org/wiki/Solow_Building The Solow Building, located at 9 West 57th Street, is a Manhattan skyscraper designed by Skidmore, Owings and Merrill's Gordon Bunshaft and built in 1974. It is located just west of Fifth Avenue, sandwiched between the 57th and 58th Street, next to such prominent buildings as the Bergdorf Goodman department store and the Plaza Hotel. Consisting of 50 stories and 689 ft. (210 m), the building's only competitor by height in the neighborhood is the GM Building, located one block north and east. Floors above the 23rd floor offer a virtually unobstructed view of northern Manhattan and a complete view of Central Park. One of the notable aesthetic attributes of the building is the concave vertical slope of its north and south facades, on 57th and 58th Street. This is similar to another of Bunshaft's creations, the W. R. Grace Building, which is no coincidence, as he had used the initial, rejected façade design for the Solow Building in his design for the Grace Building. The name of the building is attributed to Sheldon Solow, a real estate mogul who invested in the construction of the building.
