A Cincinnati museum has a new director. Officials at the Lois and Richard Rosenthal Center for Contemporary Art said today they have hired Linda Shearer as director. Shearer served the past 15 years as director of the Williams College Museum of Art in Williamstown, Massachusetts. She previously was the curator of painting and sculpture at the Museum of Modern Art in New York. The Contemporary Arts Center moved into its new, 35 million-dollar home in downtown Cincinnati last May. Shearer succeeds Charles Desmarais, who was director from 1995 until early this year.
