American connoisseur of art and antiques, world traveller, socialite, philanthropist, curator and chairman of the Philadelphia Museum of Art. Andy Warhol claimed that McIlhenny was "the only person in Philadelphia with glamour," a sentiment echoed by the Philadelphia Art Alliance, which dubbed him the "first gentleman of Philadelphia."
His involvement with the Philadelphia Museum of Art for a half century was legendary, and he served it as a curator from 1939 to 1964 and chairman of the board in 1976.
His collections of French masterpieces, 18th and 19th century silver, furniture and other decorative arts were housed in both his Rittenhouse Square townhouse and at Glenveagh Castle, his country house in Ireland. Many acquisitions were made through his interior designers Denning & Fourcade of New York City and Paris.
He died on 11 May 1986, aged 75. McIlhenny left his entire estate to the Philadelphia Museum of Art.
