Like​ the Wallace Collection in London, the Frick began life as a family house. In 1915, Henry Clay Frick bequeathed his Beaux-Arts limestone mansion on Fifth Avenue, along with its contents, to the city of New York. Shortly thereafter Frick acquired a set of twenty satin photogravure reproductions of paintings in Vanderbilt’s collection. Frick had the nous to insist that dealers allow him to trade back pictures he had outgrown, enabling him to upgrade his collection on a regular basis. The Frick Art Research Library (FARL), established by Helen Clay Frick in 1920 as a memorial to her father, has had a make-over, too.
