George Balanchine
From a young age, I grew up in the world of ballet. When I was old enough to begin studying the works of certain choreographers, no one stuck out to me (or stuck with me) to the extent than that of George Balanchine. His choreography turned the conventions of classical ballet on its head; rewriting technique and musicality to create a new genre in the world of ballet. His original works such as Jewels, as well as his interpretations and reworked versions of classics such as The Nutcracker, Don Quixote, and many more led to a whole new generation of ballet dancers, with more freedom to explore the angles and sharpness often abandoned by classical ballet.http://balanchine.org/balanchine/01/bio.html
