Mead, Rebecca (January 15, 2007). "An Acquiring Eye – Ronald Lauder's Career in Collecting Art". The New Yorker. Retrieved June 23, 2016. "One afternoon, Lauder took me to a town house, on Seventieth Street between Park and Madison Avenues, that his mother bought in the sixties, and in which she lived until her death, in 2004, at ninety-seven. Estée Lauder left an empire worth ten billion dollars, and part of Ronald's inheritance was this house, which he has added to a collection that includes residences in Florida, Paris, and London; an apartment at 740 Park Avenue; and a town house on East Fifty-second Street that was designed by Philip Johnson in 1950 as a guesthouse for Blanchette Rockefeller, who was later the president of MOMA, and which Lauder bought at auction in 2000 for eleven million dollars. There is also a country house in Wainscott, Long Island, on the grounds of which sits an eighteenth-century church that Lauder bought in Massachusetts and had moved to a more convenient spot."
