With Ballets Russes since 1916 Leon Woizikovsky (1899-1975) had enjoyed prominent roles in Nijinska's "Les noces", "Les Biches", and "Le Train Bleu" (as the Golfer). In 1939 he led the Ballet Polonais to the World's Fair in New York. "The company returned to Warsaw one day before the German invasion of Poland on September 1, 1939, and was never heard from again." Woizikovsky himself found work in the Americas during the war. Much later he helped in reconstructing Nijinska's 1920s choreographies at Diaghilev's "Ballets Russes".
