HEBRA, FERDINAND VON

born Sept. 7, 1816, Brnn, Moravia [now Brno, Czech Republic] died Aug. 5, 1880, Vienna, Austria physician who founded the New Vienna school of dermatology, which became a basis for modern dermatology. A graduate in medicine (1841) of the University of Vienna, von Hebra was influenced by Karl Rokitansky, one of the founders of modern pathological anatomy. He applied his training in pathology to a classification of skin diseases, first published in 1845. Von Hebra held that diseases of the skin were related to local irritation, disputing the previously held humoral doctrine that related them to a disease-producing condition of body fluids.
