This November, the American Ballet Theatre will perform in Cuba for the first time in half a century. The company, based in New York City, has long had ties to the island: Cuba’s prima ballerina, Alicia Alonso, moved to the United States, and then joined the ballet theatre in 1940. She became one of the troupe's biggest stars. The dancer is especially acclaimed for her interpretation of the title role in "Giselle" and for founding the Alicia Alonso Ballet Company in Cuba in 1948, which reportedly became the National Ballet of Cuba. Alonso's ballet company took off after Fidel Castro came to power in 1959 and began to lend it both personal and financial support. The ABT visit is in honor of her 90th birthday, which she’ll celebrate on December 21.
