Ballet Russe de Monte Carlo
At the age of fourteen, Eglevsky joined Colonel W. de Basil's Ballet Russe de Monte Carlo, and after six months was dancing leading roles in such ballets as "Swan Lake", "Les Sylphides", and "Les Présages". In 1935 he joined Igor Youskevitch as the company's "Premier Danseur", and a year later joined René Blum's Ballet Russe de Monte Carlo.
