Charles Baudelaire (1821–1867) was a French poet, essayist, art critic, and translator whose works and translations influenced the Symbolist movement in the late 19th century. His most prominent works of poetry include Les Fleurs du mal (1857) and the posthumous collection Le Spleen du Paris (1869), which were translated into English by William Crosby and published together as Flowers of Evil & Paris Spleen by BOA Editions in 1991.
