Ninette de Valois
'Madame', as she was called by everyone, attracted great talents to the company. She engaged Frederick Ashton as Principal Choreographer and Constant Lambert as Musical Director, in 1935. Tamara Karsavina was a dance advisor. Eventually the company included many of the most famous ballet dancers in the world, including Margot Fonteyn, Svetlana Beriosova, and, most sensationally, Rudolf Nureyev.
