DANCE

Ballet School Opening: The School of American Ballet, the dance academy founded by George Balanchine and Lincoln Kirstein, christened its lavish new quarters in Lincoln Center on Wednesday. The influential school, which is affiliated with New York City Ballet and has numerous graduates in the United States and abroad, becomes one of the few ballet academies in the United States that boards students. After 56 years as a rental tenant, in three different locations, the new school, estimated to cost $20 million, will accommodate 300 students. For the first time in its history, the school’s complex will include dormitories. The school’s officials gathered Wednesday with invited guests in a studio named after Steven Spielberg, whose $850,000 donation funded the room.
