Biographical/historical: New York City Ballet was founded in 1948 by George Balanchine and Lincoln Kirstein, and it quickly became known for its athletic and contemporary style. Balanchine served as Ballet Master of New York City Ballet from its inception until his death, in 1983, choreographing many works and creating a company of dancers known for their linear purity, sharpness of attack, and overall speed and musicality. In 1949, Jerome Robbins joined the Company as associate director and, with Balanchine, created a varied repertory that grew each season. In 1964 NYCB moved into its current home at Lincoln Center’s David H. Koch Theater (formerly the New York State Theater), where it currently is on stage 21 weeks of the year. Each December, the Company presents George Balanchine’s The Nutcracker®, which has been performed every year since its premiere in 1954. In 1966, New York City Ballet performed at the opening ceremony for the Saratoga Performing Arts Center, in upstate New York; the Company has had a residency there every summer since. NYCB also tours regularly, both in the U.S. and abroad. Following Balanchine’s death, in 1983, Jerome Robbins and Peter Martins were named Co-Ballet Masters in Chief. Today the company continues to bring dance to New York city and the world and is currently headed by co-directors Jonathan Stafford and Wendy Whelan.
