The Brooklyn Museum announced today that Anne Pasternak will succeed Arnold Lehman as director of the institution. Pasternak will join the museum on September 1, after more than 20 years as the president and artistic director of the non-profit Creative Time, and the person responsible for the “Tribute in Light” that has appeared annually next to the site of the World Trade Center since early 2002. Lehman retires after a sometimes controversial 18-year tenure.
