Grenville L Winthrop was “arguably the most discriminating and independent-minded of all 20th-century American collectors. Yet his collection of 4,000 paintings, drawings and objects is far less well-known than theirs.” He left his collection to Harvard’s Fogg Museum with instructions the art was not to be loaned. “Then, about five years ago, the director of the Fogg looked again at the fine print in Winthrop’s will. The document stipulated that, if the museum ever lent a work from the bequest, it would be obliged to pay to the Foundlings Hospital in New York City the sum of $100,000 – a fortune in 1937 when the will was drawn up, but not such a big deal in the late 1990s. In a coup so outrageous I smile every time I think about it, the director simply sent a cheque to the happy orphans, and, hey presto, the magic spell had been broken. The museum was free to lend any of the pictures anywhere, any time, and to anyone who asked. Art that had been immured in an ivory tower went global.”
