As New York’s Museum of Modern Art prepares for its new home, a new curatorial team is chosen. “Almost immediately after being chosen as the Modern’s chief curator of painting and sculpture in March, John Elderfield, 60, decided he wanted a certain kind of team to help him shape the institution’s future. Those chosen should be young(ish), he specified, yet steeped in both classical and contemporary modern art; risk-taking but also willing to collaborate; similar in outlook but different enough to challenge one another. Bold visionaries residing in solitary genius need not apply.”
