Last night, there was a terrible crash on New York’s commuter rail line, Metro North, that killed six passengers. Today we learned that one of those killed was Walter Liedtke, curator of Dutch and Flemish painting at the Metropolitan Museum of Art. The museum’s official announcement on its Facebook page says, “. . . We pay homage to him with his 2011 Connections Episode, ‘Living with Vermeer.'” I will follow suit, re-sharing Liedtke’s lovely discussion of the art he studied and loved: “Living with Vermeer.”
