Dame Margaret "Peggy" van Praagh, DBE (1 September 1910 – 15 January 1990) was a British ballet dancer, choreographer, teacher, repetiteur, producer, advocate and director, who spent much of her later career in Australia.
Peggy van Praagh was born in London and educated at King Alfred School, London. She began dancing very early in London. One review stated: "At last night's concert a dainty extra was a very charming dance by little Peggy van Praagh ... Peggy is only six but she is quite a clever little artiste and is booked again for Saturday's matinee by request."
Van Praagh joined Ballet Rambert in 1933. Later she also danced with Antony Tudor's London Ballet. Van Praagh performed in some of Tudor's ballets such as Jardin aux Lilas (otherwise Lilac Garden), Dark Elegies, Gala Performance, Soirée musicale and The Planets.
In the early years of World War II, she was heavily involved in staging lunch time ballet shows called Ballet for a Bob, which attracted large audiences of civilian and military personnel. In 1941, she was employed by Ninette de Valois largely to teach company classes for Sadler's Wells Ballet, although van Praagh also danced in a number of company productions including Les Patineurs, Comus and Coppelia in which she danced the leading role of Swanilda.
In 1945, van Praagh became a teacher at the Sadler's Wells Ballet School. She worked there until 1956. During this time she maintained a long, fruitful association with choreographer Antony Tudor. From 1956 until 1960 she undertook freelance teaching and producing in Germany, Canada, Denmark, Sweden, the Netherlands and the US.
In 1959, on the recommendation of Ninette de Valois, van Praagh was appointed Artistic Director of the Borovansky Ballet in 1960. Following the demise of the Borovansky Ballet in 1961 and its subsequent reformation as Australian Ballet, she became its founding artistic director in 1962, where she remained until 1974, and was invited back again for the 1978 season. From 1965–1974, van Praagh held the position jointly with Sir Robert Helpmann.
