The Frick Collection

The Frick Collection is an art museum located in the Henry Clay Frick House on the Upper East Side in Manhattan. It houses the collection of industrialist Henry Clay Frick (1849–1919). The Frick is one of the pre-eminent small art museums in the United States, with a high-quality collection of old master paintings and fine furniture housed in nineteen galleries of varying size within the former residence. Frick had intended the mansion to become a museum eventually, and a few of the paintings are still arranged according to Frick's design. Besides its permanent collection, the Frick has always organized small, focused temporary exhibitions.
