E. T. A. Hoffmann’s novella, Mademoiselle de Scudéri. A Tale from the Times of Louis XIV [Das Fräulein von Scuderi. Erzählung aus dem Zeitalter Ludwig des Vierzehnten], was first published in 1819 and can be considered an early example of crime fiction. (Source: Wikipedia)
Ernst Theodor Amadeus Hoffmann is one of the best-known representatives of German Romanticism, and a pioneer of the fantasy genre, with a taste for the macabre combined with realism that influenced such authors as Edgar Allan Poe (1809–1849), Nikolai Gogol (1809–1852), Charles Dickens (1812–1870), Charles Baudelaire (1821–1867), George MacDonald (1824–1905), Fyodor Dostoevsky (1821–1881), Vernon Lee (1856-1935), Franz Kafka (1883–1924) and Alfred Hitchcock (1899–1980). Hoffmann’s story Das Fräulein von Scuderi is sometimes cited as the first detective story and a direct influence on Poe’s The Murders in the Rue Morgue. His stories form the basis of Jacques Offenbach’s famous opera The Tales of Hoffmann, in which Hoffmann appears (heavily fictionalized) as the hero. He 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. (Source: Wikipedia)
