The Philadelphia Museum of Art appointed chief operating officer Gail Harrity to serve as interim chief executive officer until a permanent successor is found for director Anne d’Harnoncourt, who died on June 1.

The museum also announced its schedule of coming exhibitions, headlined by “Cézanne and Beyond,” a retrospective of some 150 paintings, watercolors, and drawings by French artist Paul Cézanne. The show will run from February 26 to May 17, 2009, and will include works by 17 artists influenced by Cézanne, including Pablo Picasso, Henri Matisse, and Piet Mondrian.

Ms. Harrity, a former deputy director of New York’s Guggenheim Museum, will continue her current duties overseeing the Philadelphia Museum’s day-to-day operations, spokesman Charles Croce said Tuesday in an interview. Associate director of collections Alice Beamesderfer will become interim head of curatorial affairs, which d’Harnoncourt had overseen, he said.

“The most important thing we want to keep intact is her legacy,” Mr. Croce said of d’Harnoncourt, 64, who died of a heart attack at her Philadelphia home. “She put a great team in place. She hired every curator.”

Mr. Croce said the museum is in the process of setting up a selection committee to find a successor for d’Harnoncourt.

A curatorial advisory group was named, including Joseph Rishel, who was d’Harnoncourt’s husband and is currently the senior curator of pre-1900 European painting; Innis Shoemaker, senior curator of prints, drawings and photographs, and Kathleen Foster, senior curator of American art.
