Yesterday, after New York Times art critic Michael Kimmelman took aswipe at former Metropolitan Museum director Tom Hoving in his analysis of the appointment of Thomas Campbell to that job, saying he was an unstable egomaniac who left the museum in reeling chaos, I asked Hoving how he felt about that. “I do have a huge ego (for good reason),” he replied, “and I was, thankfully, a bit unstable — that’s what revolutions do.”
