French novelist and art critic Joris-Karl Huysmans (1848-1907) is most known for his contributions to the literature of the Decadent movement. Huysmans, who was born and reared in Paris, first worked as a civil servant before deciding to become a writer. His best-known book, " rebours" (Against Nature), examined the life of a rich and eccentric nobleman who isolates himself from society and engages in hedonistic activities. This book brought him recognition. Together with "Là-bas," this piece elevated Huysmans to the position of a key player in the Decadent movement, which praised artifice, sensuality, and decadence. Huysmans converted to Catholicism later in life, and this spiritual transformation is reflected in his later works. He has had a lasting impact on French literature and culture.
