About E. T. A. Hoffmann:
Ernst Theodor Amadeus Hoffmann is also the author of the novella The Nutcracker and the Mouse King, on which the famous ballet The Nutcracker is based. The ballet Coppélia is based on two other stories that Hoffmann wrote, while Schumann's Kreisleriana is based on Hoffmann's character Johannes Kreisler.
Is it not in the most absolute simplicity that real genius plies its pinions the most wonderfully?
