کتاب دمیان (زبان اصلی)

Demian: The Story of a Boyhood is a bildungsroman by Hermann Hesse, first published in 1919; 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 tenth edition was the first to bear his name.

Hermann Karl Hesse (2 July 1877 – 9 August 1962) was a German-Swiss poet, novelist, and painter. Although Hesse was born in Germany's Black Forest region of Swabia, his father's celebrated heritage as a Baltic German and his grandmother's French-Swiss roots had an intellectual influence on him. He was a precocious, if not difficult child, who shared a passion for poetry and music with his mother, and was especially well-read and cultured, due in part to the influence of his polyglot grandfather.

As a youth, he studied briefly at a seminary, struggled with bouts of depression and even once attempted suicide, which temporarily landed him in a sanatorium. Hesse eventually completed Gymnasium and passed his examinations in 1893, when his formal education ended. However, he remained an autodidact and voraciously read theological treatises, Greek mythology, Johann Wolfgang von Goethe, Gotthold Ephraim Lessing, Friedrich Schiller, and Friedrich Nietzsche. His first works of poetry and prose were being published in the 1890s and early 1900s with his first novel, Peter Camenzind, appearing in 1904.

His interest in Eastern religious, spiritual, and philosophical traditions, combined with his involvement with Jungian analysis, helped to shape his literary work. His best-known works include: Demian, Steppenwolf, Siddhartha, Narcissus and Goldmund, and The Glass Bead Game, each of which explores an individual's search for authenticity, self-knowledge, and spirituality. In 1946, he received the Nobel Prize in Literature.
