"John F. Kennedy’s death is still an open wound, a story we keep retelling. It thrust his young widow onto a global stage that no one can be prepared for.

McLaurin is president of the White House Historical Association (@whitehousehistory), which Jacqueline Kennedy founded in 1961 – one of the many ways the nation has "reaped the benefits of the foundation she laid," he writes. As Jackie Kennedy mourned her husband she led a nation through their collective grief, becoming "The First Lady of the World."
