In 1926, the Irish-born dancer Ninette de Valois founded the Academy of Choreographic Art, a dance school for girls.Her intention was to form a repertory ballet company and school, leading her to collaborate with the English theatrical producer and theatre owner Lilian Baylis.Baylis owned the Old Vic and Sadler's Wells theatres, and in 1925, she engaged de Valois to stage dance performances at both venues.These events forced the company to begin touring the country, becoming known as the Sadler's Wells Ballet.The company relocated to the opera house the same year in 1946, with their first production at the venue being Ninette de Valois' staging of The Sleeping Beauty.
