What caused the final split between the Guggenheim’s Tom Krens and Peter Lewis that led to Lewis leaving the museum board? “In the months before his departure, Lewis had taken to asking: ‘If franchising all these international museums is such a good idea, then why isn’t Moma doing it? Why isn’t the Whitney doing it?’ The spin coming from the Guggenheim is that the outcome of the confrontation represents the triumph of culture, in the shape of Krens, a 6ft 5in former artist with a fondness for Harley-Davidsons, over commerce in the person of Lewis, chairman of a Cleveland insurance company. But the truth is that Lewis was becoming increasingly alarmed, not just about the financial position of a museum into which he had poured so much of his own money, but also its reputation.”
