What is Public administration as an art?
Some notable professionals in the field include Philippe de Montebello, curator of New York City's Metropolitan Museum of Art from 1977-2008. On his retirement, he was both the longest-serving director in the institution's history, and the longest-serving director of any major art museum in the world. Michael Maddox co-founded the Bolshoi Theatre in Moscow, home to Bolshoi Ballet and Bolshoi Opera who are amongst the oldest and grandest ballet and opera companies in the world. Another notable figure in arts administration is John Lane of John Lane's Ogunquit Playhouse in Ogunquit, Maine. Lane acquired the playhouse in 1950 and successfully ran the organization, still considered to be "America's foremost summer theatre," until his retirement in 1994.
