Josef Jadassohn was a dermatologist who was world-renowned not only for his devoted work and numerous contributions but also for the legacy of his coworkers and followers.1,2 Born into a Jewish family on September 10, 1863, in Liegnitz, Silesia (now Poland), Jadassohn attended medical school at Göttingen, Breslau, Heidelberg, and Leipzig. During medical school, Jadassohn became fascinated by how the pathogenesis of diseases could be revealed by studying functional pathology. After medical school, he was offered a dermatology residency position at the University of Breslau by Albert Neisser (for whom Neisseria gonorrhea is named). Although he was interested in pathology, Jadassohn believed that general pathological questions could be fruitfully studied in the field of dermatology and chose to accept the position.
