William H. Crosby was born in 1914 and raised in Oil City, Pennsylvania. He served the U.S. Army in many capacities but his expertise was within the medical field. Having published over 500 articles on various aspects of medicine, Crosby turned his attention to Charles Baudelaire after reading one of his “Spleen” poems in Les Fleurs du mal. Because Baudelaire used “spleen” to indicate an organ of anger and melancholy, Crosby provided his own translated quatrain from Baudelaire’s poems to introduce previous connotations attached to the spleen. He worked on Les Fleurs du Mal and Le Spleen de Paris for 14 years.
