Lavrovsky was born in 1905 in St. Petersburg, the son of an industrial worker named Ivanov. Leonid Ivanov changed his surname to Lavrovsky and graduated in 1922 from the
Petrograd Ballet Academy, where he had studied under V.I. Ponomaryov. He danced with the former
Mariinsky Theatre, performing such roles as Siegfried in
Swan Lake, Jean de Brienne in
Raymonda, and the lead in
Chopiniana. During the same period, Lavrovsky was also a member of the Molodoy Ballet (Young Ballet), an experimental dance collective whose members included the young
George Balanchine. Lavrovsky performed in
Fyodor Lopukhov's
Dance Symphony along with Balanchine,
Alexandra Danilova, and Lidia Ivanova. Lavrovsky's first major work as a choreographer was the ballet
Katerina, which he created for a graduation performance. The ballet told the story of a serf theater, and was choreographed to music by
Anton Rubinstein and
Adolphe Adam. In the late 1930s, Lavrovsky was made the artistic director of the ballet troupe of the
Kirov Theatre. ==Romeo and Juliet==
