 Though a relative unknown, Vsevolozhsky was a vigorous and ‘enchantingly kind’ figure with ‘astonishing insight’.Vsevolovsky was responsible for who brought about the very existence of such world-famous ballets as "The Sleeping Beauty" (Tchaikovsky/Petipa) and "The Nutcracker" (Tchaikovsky/Ivanov).In 1889, he duly instructed the Imperial Balletmaster Marius Petipa to choreograph a full-length ballet to the story "The Sleeping Beauty" for a premiere at the Mariinsky Theatre.
