Laurie A. Woodard, formerly of Dance Theater of Harlem, now teaching at NYU: “Ms. Copeland’s career, on the stage and beyond, has brought ballet into the wider culture in ways Louis XIV could not have imagined. … [Yet] the insular world of classical ballet has limited not just the number of black ballerinas; there are only a handful of black classical choreographers. And for companies other than D.T.H., black spectators are rare. The days of whiting-up are behind us, but ballet still needs to change.”
