Sergei Lifar, a famous dancer, choreographer, premier of the Paris Opera, who headed the Grand Opera Ballet company for many years, and a close friend of the legendary founder of the Russian Ballet Sergei Diaghilev, wrote two books of memoirs about him. Serge Lifar's book about Diaghilev was first published in Paris in 1939 in Russian in the amount of 615 copies, and immediately became a bibliographic rarity. Russian Russian Ballet was born in the era of the "World of Art", the first Russian seasons in Paris, which brought world fame to the Russian Ballet and, of course, the truthful and full of revelations pages of the memoirs about Diaghilev, their personal and creative relationships.
