Cynthia Kathleen Gregory (born July 8, 1946) is an American former prima ballerina. Born in Los Angeles, Gregory took up dancing when she was five, with the encouragement of her parents, who hoped exercise would stem her history of childhood illnesses. A performance by Margot Fonteyn and Rudolph Nureyev had inspired young Cynthia to study ballet. By age six, she was en pointe; and at age seven, she first appeared on the cover of Dance Magazine. She would eventually go on to dance with Nureyev in a production of Romeo and Juliet, which he had originated with Fonteyn as Juliet. He has called Gregory "America's Prima ballerina assoluta." Much of Gregory’s early training was with Carmelita Maracci. Awarded a Ford Foundation scholarship at age 14 to study with the San Francisco Ballet, she quickly rose to soloist and became shortly thereafter a principal dancer, while also dancing with the San Francisco Opera. Gregory joined American Ballet Theatre (ABT) in 1965. In 1967, when ABT was on tour in San Francisco, Gregory made an auspicious debut as Odette-Odile in Swan Lake. Her New York debut in that role later the same year marked her emergence as a major ballerina. The role is one in which her performance is still recognized as definitive. Gregory’s other lead roles include classical performances in Giselle, Sleeping Beauty, Coppélia, Don Quixote, La Sylphide, as well as contemporary works including The Eternal Idol and At Midnight. At ABT alone, Gregory danced in over eighty works, including over a dozen created for her. In 1986, Gregory was chosen to open the newly refurbished Paramount Theater in Wilkes-Barre, Pennsylvania, when it became the F.M. Kirby Center for the Performing Arts. Gregory resigned from ABT in 1991 to pursue a more varied repertoire. She continued to perform as a permanent guest artist with Cleveland San Jose Ballet, Dances...Patrelle and Connecticut Ballet Theatre until ending her public performances in 1992. Her career included guest performances with leading dance companies of the world, including National Ballet of Canada, Zurich Ballet, San Francisco Ballet, Vienna State Opera Ballet, Ballet Nacional de Cuba, and Stuttgart Ballet. She also appeared with Linda Ronstadt in Ronstadt’s music video of “When You Wish Upon a Star.” Gregory presently stages classical ballets, coaches and gives master dance classes for dance companies around the world. Her choreographic works include her solo to Bach’s “Air on the G String,” as well as a two-minute rock video for Campbell's Soup. She has been featured in advertising campaigns for American Express (“Do you know me? You know my toes!”), Raytheon, and Rolex. Gregory served as Chairman of the Board of Career Transition For Dancers (a not-for-profit organization that provides career counseling, scholarships and other vital services to dancers who, for reasons of age or injury, are making a career change) from 1991 to 2015, when Career Transition For Dancers merged with the Actors Fund of America. Since 2008, Gregory has been a member of the Board of Directors of the Isadora Duncan Dance Foundation, a non-profit organization dedicated to extending the dream, dance legacy and spirit of Isadora Duncan.In 2010, Nevada Ballet Theatre announced that Gregory will act as artistic advisor to the professional company and its affiliated academy. The Cynthia Gregory Center for Coaching was established at the company's Las Vegas studios.
