"Ernst Theodor Wilhelm Hoffmann (1776 - 1822), better known by his pen name E.T.A. Hoffmann (Ernst Theodor Amadeus Hoffmann), was a German Romantic author of fantasy and horror, a jurist, composer, music critic, draftsman and caricaturist. Hoffmann's stories were very influential during the 19th century, and he is one of the major authors of the Romantic movement.
He is the subject and hero of Jacques Offenbach's famous but fictional opera The Tales of Hoffmann, and the author of the novelette The Nutcracker and the Mouse King, on which the famous ballet The Nutcracker is based. The ballet Coppelia is based on two other stories that Hoffmann wrote. Also Schumann's Kreisleriana is based on one of Hoffmann's characters.
