Ekaterina Sankovskaya (1816, Moscow - 28 August 1878, Moscow) was a Russian dancer who graduated from the Moscow Bolshoi Ballet School in 1836. Revered for her celebrated performances in the title roles of such works as Giselle and La Esmeralda, Sankovskaya was among the most admired ballerinas of her time in Moscow. She taught ballroom dance in private houses after retiring in 1854. One of her pupils was the theatre director Konstantin Stanislavsky.[1]
