"The dancer and choreographer Jean-Georges Noverre's 'Letters on dancing and ballets' were first published in 1760, and set forth his ideas for the reform of ballet, ideas which were considered revolutionary in their day and were not fully implemented until more than a century later. 'Letters on Dancing and Ballets' is one of the most important dance books ever published, and through its influence Noverre can be seen as the grandfather of ballet as we know it today. The present translation was made by the great dance historian Cyril W. Beaumont, and first published by him in book form in 1930." (from the 2004 Dance Books printing of the English language edition).
