Hermann Hesse 
Demian 

The Story of Emil Sinclair's Childhood is a historical novel by Hermann Hesse. It was published in 1919, and the introduction was added in 1960. The first edition of Demian was published under the pen name of Emil Sinclair, the name of the storyteller. However, Hesse was later revealed to be the author, and the 10th version was quickly named after him. When it was published in 1919, this transitional novel received immediate critical and popular acclaim. A masterpiece in the history of 20th-century literature, it reflects the writer's distraction with the duality of human nature and the achievement of spiritual fulfillment.
