New York City Ballet
NYCB still has the largest repertoire by far of any American ballet company. It often stages 60 ballets or more in its winter and spring seasons at Lincoln Center each year, and 20 or more in its summer season in Saratoga Springs. City Ballet has performed "The Nutcracker", "Romeo and Juliet", "A Midsummer Night's Dream", and many more. City Ballet has trained and developed many great dancers since its formation. Many dancers with already developed reputations have also joined the ballet as principal dancers.
London Ballet
London Ballet was a short lived British ballet company founded by the British choreographer and former Ballet Rambert dancer Antony Tudor in 1938, along with Rambert members Hugh Laing, Andrée Howard, Agnes de Mille, Peggy van Praagh, Maude Lloyd and Walter Gore. With the onset of World War II, in 1940 they were invited to New York, joining Richard Pleasant's and Lucia Chase's reorganized Ballet Theater, which later became the American Ballet Theatre.
