The former POB principal Nina Vyroubova died on June 25, aged 86. Unfortunately I found almost no obituary about her (just a "dépêche AFP":

She was born in Russia in 1921, and had created the role of "la belle endormie" in Roland Petit's "Les forains" in 1945 with the Ballets des Champs Elysées. She became a POB principal in 1949 and had created many roles for Lifar.
