Pierre Louis Alphée Cazenave

Pierre Louis Alphée Cazenave (1795 to 1877) was a French dermatologist who practiced at the Hôpital Saint-Louis in Paris. Appointed interne to the Paris hospitals in 1823, he became professor agrégé to the medical faculty in 1835. At Saint-Louis he studied under Laurent-Théodore Biett, who introduced an anatomical approach to the analysis of skin disorders into French medicine, a method first developed by the English physicians Robert Willan and Thomas Bateman. In 1828 he and Henri Édouard Schedel published a practical summary of skin diseases based on Biett's lectures and observations, which became a highly influential dermatological work translated into several languages. From 1843 until 1852 he edited the Annales des Maladies de la Peau et de la Syphilis. He is credited with coining the term lupus érythémateux, lupus erythematosus, and in 1844 he first described the rare condition pemphigus foliaceus.
