Josef Jadassohn

Joseph (Josef) Jadassohn (10 September 1863, Liegnitz – 24 March 1936, Zurich) was a German dermatologist.

Biography[edit]

He was an assistant to Albert Neisser at the Allerheiligen Hospital in Breslau until 1892, the director of the university skin clinic in Bern (1896-1917), and later a professor of dermatology at Breslau University (1917-1932).

Jadassohn was among the first to take an immunological approach in research of dermatological disorders, and contributed to the understanding of the immunopathology of tuberculosis and trichophytosis. He was a pioneer in the field of allergology, and is credited for introducing patch testing for diagnosis of contact dermatitis.[1] In 1901 he described a rare childhood dermatological disorder known as granulosis rubra nasi.

Conditions[edit]

Two dermatological disorders that are named after him are: "Jadassohn's disease I" (a skin disorder originating at the elbow) and "Jadassohn's disease II" (a natal skin disorder affecting the face and scalp). Together with his assistants, Walter Dössekker (1868-1962), Max Tièche (1878-1938) and Felix Lewandowsky (1879-1921), he shares the following eponymous medical conditions:
