The New York residence of Henry Clay Frick (1849-1919), a prominent art collector and industrialist, was designed by Thomas Hastings and completed in 1914. The house, located at One East 70th Street, was opened in December 1935 as a public art gallery, The Frick Collection. Correspondence, telegrams, lists, notes and invoices document the furnishing and interior decoration of the house from 1913 to 1920.
