Princess Norodom Buppha Devi, granddaughter of the late King Sihanouk and half-sister of the current king, toured the world in the 1950s and ’60s as one of the leading dancers of the Royal Ballet of Cambodia. In the 1990s, after the years of the Khmer Rouge and the later Vietnamese invasion, she located surviving dancers and musicians and refounded the company, and she’s now training a new generation.
