Context: Gelsey Kirkland (born December 29, 1952) is an American ballerina.  Kirkland joined the New York City Ballet in 1968 at age fifteen, at the invitation of George Balanchine.  She was promoted to soloist in 1969 and principal in 1972.  She went on to create leading roles in many of the great twentieth century ballets by Balanchine, Jerome Robbins, and Antony Tudor including Balanchine's revival of "The Firebird", Robbins' "Goldberg Variations", and Tudor's "The Leaves are Fading".  Balanchine re-choreographed his version of Stravinsky's "The Firebird" specifically for her.  She left the New York City Ballet to join the American Ballet Theatre in 1974. John Clifford, born June 12th is the founder / artistic director of the original Los Angeles Ballet (1974–1985), and the chamber sized touring ensemble, Ballet of Los Angeles (1988–1991) and the creator of “CASABLANCA, THE DANCE” produced by Warner Bros.  Theatre Ventures, Inc. (which premiered in Beijing, China at the historic "Great Hall of the People" in 2005) and his Los Angeles Dance Theater.  Before that time,Clifford was a principal dancer and choreographer with George Balanchine’s New York City Ballet, (1966–1974) and guest artist from 1974–1980, and was widely considered to be Balanchine’s protégé (Saturday Review).  He choreographed his first (of 8) ballets for the NYC Ballet under Balanchine at age 20 thus making him the 2nd youngest choreographer in history ever to be attached to a major company.  The first was Balanchine himself who was 20 yrs-old when he choreographed his first ballet for Serge Diaghilev's "Ballets Russes."  During his time with Balanchine, in his early 20's, he also was a guest choreographer with co's ranging from the San Francisco Ballet, to the Royal Winnipeg Ballet, to the Deutsche Oper Ballet in Berlin.  Clifford's works were also featured in many TV shows and movies, such as "Flashdance," "The Man Who Loved Women," and TV series such as "Dynasty," "Glitter," and other shows produced by Blake Edwards and Aaron Spelling. Les Ballets 1933 was a ballet company started by Boris Kochno and George Balanchine, which Balanchine used to create new works that were completely his own, set to music that no one had yet choreographed.  The company ran for less than four weeks in 1933 and tailored itself to small, wealthy audiences in Paris (the Théâtre des Champs-Élysées) and London (Savoy Theatre), but despite its scale, it came out with works that Balanchine later used to instruct at his School of American Ballet, and in the programs of his later companies.  Outside a theatre for Les Ballets, Balanchine first met Lincoln Kirstein. Balanchine method is a commonly used alternative name for Balanchine technique, a ballet performance style invented by George Balanchine (1904-1983) during his long career as a dancer, choreographer, and teacher.  Balanchine had talked about documenting his technique but never accomplished this goal.  After his death, the George Balanchine Foundation was formed to preserve his technique and choreographic works. Patricia Wilde (born 1928 in Ottawa, Ontario) is a former principal ballerina of New York City Ballet, where she danced every major role in the repertoire, many of them created especially for her by George Balanchine.  Following her retirement from NYCB she would become a famed ballet mistress and teacher.  In 1982 she was appointed artistic director of Pittsburgh Ballet Theatre where she served until 1997.  She is a recipient of the Dance Magazine Award and the 56th Inductee into the National Museum of Dance Hall of Fame.  Her biography "Wilde Times: Patricia Wilde, George Balanchine and the Rise of New York City Ballet", by Joel Lobenthal was published in 2015 by the University Press of New England. George Balanchine to Antonio Vivaldi's "Concerto Grosso in B minor" and the first movement of his "Concerto Grosso in E major", Op. 3, nos. 10 and 12, respectively; in 1976 he added Arcangelo Corelli's "Sarabanda, Badinerie e Giga", second and third movements.  The premiere took place on November 21, 1957, at City Center of Music and Drama, New York, with lighting by Mark Stanley.  The original version placed the musicians on stage with a square dance caller calling the steps; from its 1976 revival the caller was eliminated, the orchestra placed in the pit, and a solo added for the "premier danseur" to the Corelli "Sarabanda".  The Pacific Northwest Ballet restored the caller for one performance at the 2007 Vail International Dance Festival. Balanchine technique is the ballet performance style invented by dancer, choreographer, and teacher George Balanchine (1904-1983), and a trademark of the George Balanchine Foundation.  It is used widely used today in many of Balanchine's choreographic works.  It is employed by ballet companies and taught in schools throughout North America, including the New York City Ballet and School of American Ballet, where it first emerged. Heather Watts (born September 27, 1953), was a principal ballerina with New York City Ballet.  A native of California, Ms. Watts was born as Linda Heather Watts in Long Beach on September 27, 1953.  As a little girl, she was a troublemaking child.  She had always wanted to be an actress.  An acting coach advised her taking ballet classes, seeing as she was incredibly dramatic (and clumsy).  She started dancing at the age of 10, came to New York at the age of 13 on a Ford Foundation summer scholarship to attend the School of American Ballet, the official school of the New York City Ballet.  She moved permanently to New York at age 15, again on a Ford Foundation scholarship to the School of American Ballet.  Watts joined the New York City Ballet in 1970 and was promoted to principal dancer by company founder George Balanchine in 1979.  George Balanchine took Watts into his companies "because he would not let such a talent disappear."  During Ms. Watts's tenure with the company, she had numerous principal roles created for her by George Balanchine, Jerome Robbins, and Peter Martins among others.  Mr. Balanchine gave Ms. Watts the principal roles in many of his existing masterpieces, including "Agon", Concerto Barocco, "Apollo", Symphony in C, "Theme and Variations" and "Serenade".  Ms. Watts performed around the world and starred in numerous "Dance in America" television programs, and she performed opposite frequent partner Mikhail Baryshnikov at the White House in a national televised performance of Balanchine's "Rubies" for President and Mrs. Carter.  Ms. Watts retired from the stage in a gala performance at Lincoln Center in 1995. Paul Boos (born June 2, 1958 in Sioux Falls, South Dakota) is an American dancer, balletmaster, archivist, and répétiteur.  He danced with New York City Ballet from 1977 until 1990 before becoming a guest teacher for Royal Danish Ballet.
