Answer:
George Balchaline
Step-by-step explanation:
In the early twentieth century, the Russian theatre producer Serge Diaghilev brought together some of that country's most talented dancers, choreographers, composers, singers, and designers to form a group called the Ballet Russes. The Ballet Russes toured Europe and America, presenting a wide variety of ballets. Here in America, ballet grew in popularity during the 1930's when several of Diaghilev's dancers left his company to work with and settle in the U.S. Of these, George Balanchine is one of the best known artists who firmly established ballet in America by founding the New York City Ballet. Another key figure was Adolph Bolm, the first director of San Francisco Ballet School.
