Following a Ph.D. in art history at Harvard and five years at the helm of Montreal’s Museum of Fine Arts, he came to the Philadelphia Museum (1964-78), where he created new departments for American and 20th-century art and for photography and hired several important curators (notably Anne d’Harnoncourt, who eventually became director herself). In Cleveland (1983-93), he transformed the museum from a respected but staid institution into a regional powerhouse that helped fuel cultural tourism in the then-struggling city. – The Philadelphia Inquirer
