Hermann Karl Hesse (German: [ˈhɛʁman ˈhɛsə] ; 2 July 1877 – 9 August 1962) was a German-Swiss poet and novelist, and winner of the 1946 Nobel Prize in Literature. His interest in Eastern religious, spiritual, and philosophical traditions, combined with his involvement with Jungian analysis, helped shape his literary work. His best-known novels 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. Hesse was a widely-read author in German-speaking countries during his lifetime, but his more enduring international fame did not come until a few years after his death, when, in the mid-1960s, his works became enormously popular with post-World War II generation readers in the United States, Europe, and elsewhere.
