Anne d'Harnoncourt: Discerning Enthusiasm for Art.

By any measure, Anne d'Harnoncourt's tenure as director of the Philadelphia Museum of Art, cut short by her sudden death on Sunday at 64, was distinguished. It shone forth in major acquisitions, successful fund drives, vast gallery renovations, a marvelous rehang of the collection and, above all, her refusal to let the museum become a three-ring circus. Having seen the Philadelphia museum -- or at least its steps -- become a destination after the 1976 film ''Rocky,'' she did not succumb to showy architecture; the new wing being planned at the time of her death has been designed by Frank Gehry, yet will go underground.
