[From the New World. Louis A. Duhring and dermatitis herpetiformis].

Louis Adolphus Duhring (born December 23, 1845) died in Philadelphia, the city of his birth and life work, on May 8, 1913. After medical school, he studied for two years in dermatology departments in London, Paris and Vienna. As a student in Vienna, he was under the tutelage of Ferdinand von Hebra, when the brilliant clinician and teacher was at the zenith of his fame. Duhring's series of 18 papers--published between 1884 and 1891--gave him an important and recognized position as one of the leading dermatological thinkers of the world. These publications described the skin disease which he named "dermatitis herpetiformis" (Duhring's disease). His assertion that dermatitis herpetiformis was a distinct dermatological disease process aroused at first considerable opposition. Moriz Kaposi, at that time the doyen of the Vienna school of dermatology, attacked his views with vigor and tenacity. Louis A. Duhring--this modest, unassuming, quiet-working, gentlemanly physician--made monumental contributions to American dermatology and played a significant role in establishing Philadelphia as one of the great centers of dermatologic activity.
