Demian: The Story of Emil Sinclair's Youth is a Bilungsroman by Hermann Hesse, first published in 1919, but a prologue was added in 1960. Demian was first published under the pseudonym "Emil Sinclair", the name of the narrator of the story, but Hesse was later revealed to be the author. The name "Emil Sinclair" was chosen because he was a friend of the poet Novalis, whom Hesse adored. The novel was written in just three weeks.
